introduction Public, affordable and subsidized housing, is a topic that has been thoroughly studied and examined. Experiments in Public Housing focuses on the architecture of housing projects over time. In addition, this publication recognizes other associated realities of public housing and their potential influence on design. Through the careful analysis of mostly local precedents, this study searches for points of departure for innovation within the typology. This book is not an outright biased critique, nor is it a detached survey. Where warranted, a position is taken to provoke new ideas and possibilities. The main objective is the identification of themes, issues and patterns that could possibly bear fruit in terms of generating new ideas for public and subsidized housing.

Research Methodology & Scope Experiments in Public Housing is a two volume product of a semester-long period of research. The first volume contains the research and analysis of subsidized housing as a whole. The class has referenced books and articles in addition to conducting interviews covering housing history, policy, code, and financing. These books and articles span multiple generations of discourse on public housing. Sources ranged from classics such as, The Death and Life of Great American Cities by Jane Jacobs to an interview on current uses of a pro-forma. To synthesize and analyze the large amount of information regarding this topic, the publication is divided into separate, but relatable chapters, each covering an important feature related to the examination of public housing.

politics, policy & Pattern What was affordable housing like before public housing?
A brief history of public housing
Housing was not a policy issue until the 1850’s, when industrialization and job creation flooded urban centers and created a critical housing shortage. The demand for housing was dealt with by private landowners who turned single family homes into dense, subdivided housing tenements, cramming up to five families in a single home. The New York state government attempted to ameliorate this with a Housing Act in 1879, meant to improve conditions with fresh air, fire protection and indoor plumbing. Crammed tenements and slums continued to be the norm for decades, while local governments provided various laws to improve conditions without much success. The Depression sparked discussion about federally funded housing. Catherine Bauer, author of Modern Housing (1934), predicted the pitfalls of concentrated poverty and argued for a non-profit, mixed-income family housing that would allow for differences in wealth to be invisible, with shared amenities and an efficiency of construction that would bring affordability. She argued against the growing trend in affordable housing to visually stigmatize the poor by relegating them to aesthetically distinct, stark modernist housing blocks, arguing that concentrated poverty would only worsen conditions for the impoverished.
The 1937 Housing Act was the first federal program for low-cost, publicly-managed and owned multi-family developments, modeled after initiatives started by other cities, most notably, New York City’s “First Houses” built in 1935, the first state-funded public housing in the US. The original intent of the building projects started by the Housing Act was “to alleviate present and recurring unemployment and to remedy the unsafe and insanitary housing conditions and the acute shortage of decent, safe and sanitary dwellings for families of low income” (US 1937). The New Deal in 1940 subsidized middle-class housing. Until the 1970’s, public housing was largely middle class and white, and seen as modern and sleek. Popular belief in the 40’s was that high rises in the style of modernism could improve living conditions with better light and ventilation. Radical ideas of clearance were also being enacted in legislation, as in the Housing Act of 1949, which emphasized slum clearance for new housing developments. The 60’s saw the emergence of class strife and the Civil Rights Act of 1964 in addition to government funded interstate highway projects marked the beginning of the flight of whites from racially integrated projects and into the suburbs. Federally funded housing got bigger and denser, and a trend for the
Political Engagement lower class to remain in the city while the middle and upper classes moved out emerged. Income limits that gave preference for the poor and disadvantaged were set, reinforcing the tendency for affordable housing to be homogeneously poor. In the late 1960’s the negative effects of concentrated poverty had surfaced. The US Department of Housing and Urban Development (HUD) was formed in 1965, and prohibited the construction of high-rises for families. This failure manifest itself in 1972 with the demolition of the Pruitt-Igoe high rises. In 1978, President Nixon froze new federal housing projects, and HUD devised Section 8 subsidy vouchers to encourage the private sector to build affordable homes, shifting the burden from the government. In 1981 rent ceilings were eliminated and then reintroduced in 1987, this time with preferences for those who were involuntarily displaced by slum clearance. In 1992, federal housing preferences were largely eliminated and flexibility was restored to local authorities and the private sector. In 1993, HUD formed HOPE VI, a plan to revitalize public housing by converting projects into mixed-income developments, in the hope that smaller developments would lead to more personal investment in the property, better upkeep and thus a higher quality of living. Today, HOPE VI is being phased out in favor of Choice Neighborhoods, a similar program that builds on the successes of HOPE VI by situating smaller, mixed-income developments in close proximity to good infrastructure like schools to improve chances for the long term success of the neighborhood.
Rental housing is heavily influenced by government rules and fees. Most lending institutions require larger down payments and charge a higher interest rate for rental property mortgages, and insurance companies charge higher premiums for rentals. For example, in Michigan it costs $200 more per month to provide a typical 3 bedroom rental home than it would for a homeowner. Political participation is the best way for tenants to keep housing affordable. More importantly, political action is sometimes necessary to getting affordable housing projects built in the first place. For example, in 1965, the US Department of Housing and Urban Development designated part of Boston’s South End as an “urban renewal area”, planning to replace low-income communities with upper class residences. A Puerto Rican community banded together to form an “Emergency Tenants Council”, allied with an architect to re-asses the condition of the area to be demolished, and fought for mixed-income housing, on-site relocation and the establishment of a more visible ethnic landmark. By receiving support from local organizations and Puerto Rican groups in other cities, local and federal representatives and civic leaders, the Boston Redevelopment Authority granted their request, after a long battle.

1. Crowding and Slums pre-1930’s
This period was marked by overcrowding and slum conditions. Many rooms in tenements had no or few windows and very poor light. Air quality was poor and there was little ventilation. The monotony of tenement design only worsened conditions.
“Dumb-bell Tenement” designed to bring light and air via light shafts - still not enough to combat hyperdensity. In some tenements, whole families lived in single rooms.
2. Livable Housing 30’s - 60’s
State-funded projects like NYC’s First Houses and, later, the federal government’s 1937 Housing Act were the responses to slum conditions. These projects were designed as low rise neighborhoods, often with narrow, snaking floor plans that maximized surface area and window space in order to bring in better air and light.
Bromley-Heath is an example of a “livable” low-rise constructed after the 1937 Housing Act, meant to improve light and air conditions. Movements | History 14
3. Concentrated Poverty Post-war, 50’s - 70’s
As a result of the success of the projects made after the 1937 Housing Act, popular opinion was that public housing should be done on an even larger scale to replace the enormous number of slums and fulfill the need for low-income housing. This meant the construction of multi-acre projects, many with several high rises in efficient layouts. Some architects designed these projects with the belief that towers with modern aesthetics on “super blocks” would give tenants a feeling of well-being and individuality (relative to the existing city). The decisions to concentrate ethnically homogeneous and uniformly poor populations in high rises would prove to have negative consequences.
Pruitt-Igoe in St. Louis (above right, and opposite page) and Cabrini Green in Chicago (right) were some of the largest housing projects built during this era and examples of concentrated poverty.

4. Reaction to Failure 70’s - 90’s
By the 70’s, some federally funded projects had fallen apart; problems included crime, disrepair and vacancy. The demolition of the vacant Pruitt-Igoe in 1972 was a public, televised symbol of this failure. President Nixon froze federally funded housing, and Section 8 subsidies began. These were an attempt to reward private developers for building their own affordable housing. In response to the many people involuntarily displaced by slum clearance in prior decades, preference was given to these people for new housing developments. In 1992, HOPE VI began revilitalizing the worst public housing projects into mixed-income developments, based on ideas of new urbanism and defensible space. The aim was to address the problems of the prior era - hyperdensity, monotony, homogeneity of race and income, and funding issues.

5. The Present Day 90’s - ? 1,000’
In 2010, HUD began to phase out HOPE VI, and in 2011 announced “Choice Neighborhoods”, an initiative that builds on the success of HOPE VI projects (mixed-income, small-scale) while addressing their issues (disconnection from key services). Choice neighborhoods awards grants to developers who plan affordable, mixed-income housing projects in close proximity to key services like public schools, transportation and parks. This improves chances of success for future generations and the longevity of the project in general.

a closer look at policy Housing Policy Policy relating to housing has spanned many decades and impacted countless housing projects across the United States. Several noteworthy policies and programs have had a monumental effect, specifically on the development of public housing. Everything from the New Deal to the creation of HOPE VI further added to what the institution of public housing is today. Beginning with the Housing Act of 1937, government involvement in housing began. The 1937 Act was the first program that focused on low-cost, publicly-managed and owned multi-family developments. The creation and importance of civic housing projects began here. Only adding to the proliferation of public housing was the 1949 act that allowed the use of slum clearance as a means to new housing developments. The formation of the US Department of Housing and Urban Development (HUD) in 1965 resulted in a designated body responsible for the conditions of the country’s housing projects. All future programs and policies were created and governed by this Department. The creation of the Section 8 voucher program also has had a great deal of impact on the affordable, public and subsidized housing. The program allows for residents to have their rent supplemented by HUD, which makes housing more affordable for them. The biggest and most notable policy to come
from HUD was the HOPE VI program created in 1993. This program took stock of the current conditions and set out to fix them with the aim to re-invent the image of public housing. It established the new bar for the design, construction and operation of public housing. As a result, numerous housing authorities across the country applied to the program in order to address their failed housing projects. Lasting for more than 15 years, this program has definitely left its mark as an influential policy trend in the public housing sector. Replacing the HOPE VI program is a relativity new initiative, Choice Neighborhoods, created in 2010 by HUD. This is the newest in the long history of housing policy that aims to further develop and address the issues surrounding public housing. As suggested at with its name, the current program adds a new focus on the role of community. Identifying a larger community for new housing projects to be a part of is stressed, something that has not been of central focus in previous policies.
A Policy Case Study: The HOPe vI Policy
A Housing Case Study: Orchard Gardens
The housing policy that emerged at the beginning of the 1990s was HOPE VI, a program focused on transforming the worst public housing projects into mixed-income developments. It has been referred to by the Secretary of Housing & Urban Development at the time, Henry Cisneros, as “the last grasp for public housing.” HOPE VI was initiated by the observation of poor public housing options. As a result, Congress created a commission to investigate the issue. The aim was to identify “severely distressed” public housing developments, assess strategies to improve conditions and prepare a national action plan for dealing with the problem. In 1992 the findings of the Commission concluded that roughly 86,000 of the 1.3 million public housing units nationwide qualified as severely distressed and that a new and comprehensive approach would be required to address the range of problems existing at these developments. As a result, the HOPE VI program was enacted in October of 1992. Beginning in 1993, any public housing authority that had severely distressed public housing units in its inventory were eligible to apply to federal funds under the new program. As of 2010, 132 housing authorities were awarded funds under HOPE VI totaling $6.1 billion. 96,200 public housing units were demolished and 107,800 new or renovated housing units were created. The demise of the HOPE VI policy came in 2010 when no funds were allocated for the program. Instead, the new “Choice Neighborhoods” initiative was allocated a $250 million budget.
Orchard Gardens is the perfect project to use as an example of the influence by many trends in policy. The Housing Act of 1937 allowed for Orchard Park to be created from sixteen acres of traditional housing and developed into twenty-eight brick buildings in a superblock configuration. The project was intended as a means of last resort for those in need of housing. As a result, Orchard Park was designed to provide just that, housing, and not much more. Forty years after the creation of Orchard Park, the condition of the development was in such disrepair that crime & violence had overtaken. The development had a high vacancy rate due to no one wanting to live in such horrible conditions. Hearing the voices of the community, the Boston Housing Authority (BHA) stepped in and initiated plans to modernize the buildings. This phase of “Comprehensive Modernization” can be seen in many housing developments across the country spanning the 1980s to 2000. Seeing the shift from simply a last resort for housing to actual homes filled with possessions, the new plan aimed at expanding the units and creating defensible space. However, the “CompMod” proved to be very expensive and the BHA was forced to look elsewhere to address Orchard Park. Realizing something else needed to be done, the BHA applied for the HOPE VI program in 1993. Several phases of intervention were planned and resulted in 205 new units in the on-site phases. Offsite phases were completed afterwards, ending with the Homeownership Phase in 2010 which resulted in 20 new units and included compliance with LEED standards. A Closer Look at Policy | History 20

RESPONSE TO MODERNISM Themes of the Twentieth Century Modernism The Moratorium Pause and Preservation HOPE VI & New Urbanism
26
Themes of the Twentieth Century The architecture of public housing is a reflection of societal values. By examining the design techniques and principles used in public housing design, reflections of a period’s ideals begin to emerge. Before those ideals materialize into common practice, there are contextual influences such as policy, publications, economic standing, and forwardthinking projects that shape the physicality of innovation. The Modernist era of public housing saw the integration of innovative design with the need for low-income housing. The efficiency of the standardized potential of Modernism made public housing financially possible. Coinciding with the arrival of Modernism was the rejection of slums, reinforced by slum-clearance policies. After forty years of Modernist public housing design, the style faced the same fate as the slums. HOPE VI is the form of policy through which the government recognized the failure of Modernism in public housing. The innovation that shifted public housing design away from Modernism wasn’t as direct as the arrival of the Modernist style. This is perhaps a result of the idea that the New Urbanist perspectives involve the subjective nature of human interaction whereas Modernism focused on the objective terms of standardized, universal design. The period of “Pause and Preservation” witnessed a change
in mindset when architects took to drafting plans. Designers considered the inhabitant’s perspective, prioritizing the street level as Jane Jacobs suggested. Policy reflected this shift in 1990 when the government mandated public participation in the design process. As the perspective shifted to the desires of its inhabitants, an idealistic insight surfaced in public housing design. Urban dwellers craved suburban elements, characteristics from the very movement that caused the decline of city centers starting in the 1950s. New Urbanism implementation into public housing design is a relatively new development. What remains to be seen is how these principles will be able to weather potential shifts in demographics, such as those that Modernism experienced with suburbanization and white flight from urban centers. The suburban vernacular in most HOPE VI projects presents other inquiries, such as whether or not contemporary architecture could be both efficient and conform to its inhabitant’s ideals. What is the next innovation in public housing design?

Themes of the Twentieth Century | Response to Modernism 30
The Arrival of Modernism and the Birth of Public Housing The emergence of Modernism in public housing and the advent of public housing itself was a symbiotic relationship intended to resolve the housing crisis that followed the Great Depression. At first, Franklin D. Roosevelt passed the National Housing Act of 1934 as part of the New Deal to in part stall the heavy volume of bank forclosures on family homes. With this act, he also created the Federal Housing Administration (FHA). The Housing Act of 1937 established the Public Housing Administration (PHA) and thus was the first legislation that funded public housing in the United States. The PHA’s role was to grant subsidies to local Public Housing Authorities and to establish maximum income requirements. The intent was to at once alleviate the nation’s housing crisis while providing jobs through public works projects. In addtion, the bill encouraged using the projects as a means for slum clearance, mandating that for every one housing unit demolished one unit must be built. In the same year, both Walter Gropius and Marcel Breuer moved to America, bringing with them new ideas in Modernist design. Gropius demonstrated in Aluminum City Terrace, a public housing project for defense workers in Kensington, Pennsylvania, that Modern architecture could efficiently enhance the lives of its dwellers.
Catherine Bauer, protegé and lover to urban critic Lewis Mumford, traveled to Europe and approved of the Modernist designs that she observed. She published her book Modern Housing in 1934 detailing her findings. She believed that modern public housing should be planned, built slowly, and contain few amenities. She went on to co-author the Housing Act of 1937 and advised five presidents on housing policy. While architects like Gropius and Breuer experimented with the implications of Modern design on public housing, Le Corbusier idealized the efficiency that could penetrate every scale, from unit to master plan, in his project La Ville Radieuse. Le Corbusier had begun working on the ideals of La Ville Radieuse in the 1920s, but it wasn’t until after convening with the Congrés International d’Architecture Moderne (CIAM) that he published the project in the Athens Charter in 1943. Inspired by the human anatomy and centered along a linear spine, the project supported superblocks and celebrated the automobile. At its heart, standardized cruciform high-rises were spaced out on large blocks of expansive green space, an ideal that generated an era of skyscraper-in-the-park designs in public housing. The principles of La Ville Radieuse seemed like an apt design for maximum efficiency in solving the United States’ housing crisis.

Le Corbusier’s La Ville Radieuse (Radiant City). Le Corbusier’s design initiated the “skyscraperin-the park” ideals in public housing during the 1940s and 1950s.
Modernist housing projects were at first successful. Up until World War II, public housing projects only permitted predominately white, working class families to inhabit the units. Those on welfare were seldom selected. As a result of its initial success, the government passed the Housing Act of 1949. The legislation encouraged further slum clearance, in which the government would pay for 2/3 of the site acquisition costs. The demolition of the slums in Boston’s West End for a Modernist project was exemplary of the Act’s intent. The government was also anticipating a sharp increase in housing needs as soldiers returned home from the battlegrounds of World War II. The bill authorized the funds for 800,000 units. While the government correctly predicted the influx of soldiers and the subsequent swelling of housing needs, it couldn’t have predicted the massive demographic shift that would alter the contextual environment the Modernist projects were reacting to. The 1950s marked a period of affordable suburban living and declining city centers that changed the demographic landscape of public housing. The Modernist principles that guided the design of public housing began to reflect this shift in the form of crime and poverty. What followed was the descent of public housing and the development of a stigma that remains today.

The Moratorium: Why Modernism Failed By the 1960s, the garden communities that Catherine Bauer had envisioned were in reality “warehouses for the poor.” Levittown, New York was constructed between 1947 and 1951, demonstrating that the single-family home in the suburbs was within reach for the 16 million returning soldiers. Levittown set the stage for modern suburbia, sparking the white flight from urban America. Government policy supported this with home loans geared toward suburban single-family homes and the Eisenhower Interstate System. As the white, working class families moved to the suburbs, predominantly black families on welfare moved into public housing. Inhabitants of public housing became predominantly black in the 1950s and 1960s. In 1964, the families of Boston’s six large housing projects were 80% white and only six years later in 1970 the families were 70% black. The severe demographic shift that urban housing projects experienced was also external. A changing average family size influenced the type of desired unit plan. The urban environments in which public housing was built was decaying and hemorrhaging economic activity. The physical conditions of the buildings deteriored to the point where some units were deemed uninhabitable. Politicians were using slum-clearance and public housing policy to uproot black communities and relocate them further from the city center.
Designers responed to the changing inhabitant makeup with more Modernism. The units remained standardized in three story brick walk-up buildings. The superblocks remained and courts wove around the non-contextual buildings. Architects began placing the repeating forms at an angle to the street, attempting to visually separate the project from the surrounding neighborhoods, isolated on their own superblock. The results exacerbated the state of public housing. The crime, poverty, and blight that developed in housing projects was spreading to the surrounding areas. In 1961, Jane Jacobs published The Death and Life of Great American Cities. She offered a glaring and influential critique of the slum-clearance programs and neighborhoods designed using Modernist principles. She stressed that successful neighborhoods were designed with the inhabitants in mind, not efficiency. Design alone could not solve the deep-seated social issues that families of public housing projects faced, issues that Modernist architecture induced from the start. Critic Charles Jencks noted that the demolition of the Pruitt-Igoe project in St. Louis, Missouri on July 15, 1972 marked the end of Modern Architecture. About six months later on January 8, 1973, George Romney, then director of the Department of Housing and Urban Development under Nixon, declared a moratorium on funding for all new public housing projects.
Charles Jencks:
“Modern Architecture died in St. Louis, Missouri on July 15, 1972 at 3:32pm, when the infamous Pruitt-Igoe scheme, or rather several of its slab blocks, were given the final coup de grace by dynamite.”

The Moratorium | Response to Modernism 34
A Period of Pause and Preservation In the year after the Moratorium, Congress passed the Housing and Community Development Act of 1974. The legislation acknowledged the distress of the nation’s public housing stock and the blight spreading around urban centers. The bill also provided funds for the rehabilitation of housing projects and initiated the Community Development Block Grants (CDBG). This policy set the mood for the rest of the seventies. Architects and planners reexamined the principles of public housing design and suggested mainly cosmetic solutions for existing projects. In rehabilitating housing projects, designers couldn’t address the underlying issues of site, form, and building placement. Only new construction could incorporate the ideas from Kevin Lynch’s The Image of the City and Oscar Newman’s Defensible Space. Once Reagan was elected, his administration passed the Housing and Urban Recovery Act of 1983. This act stripped away the rehabilitation program and expanded the Section 8 voucher program. The administration implemented a fiscally conservative national housing policy, cutting the Department of Housing and Urban Development’s funding in half. The policy of the two decades after the Moritorium accounts for the drop in growth of the public housing stock.
Between the 1970s and 1980s, a combination of projects, publications, and events altered the perspective from which architects and planners designed public housing projects. The ideology of public housing evolved from a tool of social reform to an active participant in community building. Architects abandoned the idea that design alone could solve social ills and turned to the works of Jacobs, Lynch, and Newman for guidelines for successful housing solutions. Lynch detailed how the human mind mapped out urban infrastructure. His study suggested a return to the small blocks that Jacobs would argue for a year later. The superblock and its monotonous structure were deemed counterintuitive to the mind’s natural mapping function. Newman suggested that less public space generated less crime. This idea contributed to the ideals of a home that people held in that they would have more private outdoor space. Finally in 1977, a group of designers from California published A Pattern Language, visually diagramming and setting standards for Jane Jacobs’ principles. In addition to the influential publications of the time, Hugh Stubbins and John Sharratt designed Warren Gardens and Villa Victoria, respectively, both townhouse-style developments. Both architects showed that the vernacular ideal that the public desired could be achieved in public housing. The townhouse style Villa Victoria followed some of Jane Jacobs’ preferences, such as being low housing, positioned close to the street, having private front porches or stoops, and including a mix of building heights, types, and uses.
Design Guidelines: 3-story height limit Units facing the street Private exterior-unit entries Parking in small lots Secure common outdoor spaces Non-stigmatizing project image Local design that considers context

HOPE VI Counts on New Urbanism for Success The 1970s and 1980s marked the period of pause where planners and architects shifted their perspective of public housing to the ideals of community. It wasn’t until 1990 that the National Affordable Housing Act (NAHA) initated the early HOPE programs and mandated public participation. NAHA maintained the one-for-one condition, where for every unit of housing demolished, one unit had to be built. The early HOPE programs included a Comprehensive Modernization program (CompMod). In terms of policy, developers could use funds from the Comprehensive Grant Program (CGP) to renovate existing, distressed housing projects. The one-for-one policy kept the housing stock nearly even for the three years after NAHA was passed. When the government established HOPE VI funds, they eliminated the one-for-one condition, encouraging the demolition of Modernist-style housing projects and the construction of lower-density communities. This policy accounts for the steady decrease in the housing stock following the implementation of HOPE VI. While HOPE VI was signed into law in 1993, it wasn’t until 1998 that it was formally recognized, the same year that HUD met with the Congress for the New Urbanism in Baltimore. At the convention, the two organizations determined a set of New Urbansim guidelines for successful public housing design.
The mandate for public participation altered the design process and the aesthetic product of public housing. The inclusion of the public was a cognizant influence of Jane Jacobs, who argued that the community should be involved in community development. The public’s input, however, revealed a trend that permeated public housing designs across the nation. Vinyl siding, gables, dormers, and porches became commonplace among HOPE VI housing projects. Low-income urban inhabitants were yearning for the suburban elements that their wealthier counterparts left the city for beginning in the 1950s. Jane Jacobs argued for local, contextual design, but similar suburban attributes were used in HOPE VI projects across the nation. Public housing design appears to be falling back into the same kind of universalism that Modernist design championed, only the ideals are different as reflected by the public’s participation in the design process. Jane Jacobs started the process of influence that shifted designers’ perspective to that of the inhabitant. While this has greatly improved the fundamental site design of today’s public housing, the architectural aesthetic needs to be addressed once again. Addressing this issue is perhaps best done by looking toward the past. Public housing’s response to Modernism demonstrates how contextual environments influence its evolution, and how innovation can be a culmination of works that is perfected through materializing iterations.
Design Guidelines: Design neighborhoods around 5-min. walk Mixed building types Small blocks and connected streets Include community-building amenities Mixed-income Hide parking in small lots Streetside units with private entrances Mandated public participation in design

The lower Roxbury area of Boston was studied in an effort to examine the factors and circumstances that have resulted in the highest concentration of subsidized housing in Boston. The area has a dense and complex history of development over time as the city of Boston expanded, but in particular in regards to the urban renewal efforts done by the city to revitalize the area. Some of these housing projects precede the post-war era while others were realized as a result of policy and changes to the urban morphology of the area. In this case study, an in depth analysis was made on the evolution of the urban fabric dating back to a over century in an effort to identify forces that might have precipitated the density of subsidized housing in the area. The area at large over the decades seems to have been under the influence and control of broader city planning issues having to do with connecting the different areas of the city as it progressively expanded outwards. As a result, the area is characteristic of the effects of the different policies and changes to the urban fabric put in place over the decades that have changed the make up of the neighborhood as a result, some of which influenced the placement of a significant number of the city’s subsidized housing projects in this area.

Public housing in the United States started out with a bang, and no other city exemplified this housing explosion more than Boston. In the first twenty years after the Boston Housing Authority was founded in 1935, the city’s twenty-five largest projects were built. This large-scale housing implementation was focused on the ideas of slum clearance and job creation. After 1955 there was a sharp drop in the number of new BHA-funded housing projects.

From the 1960s through the 1980s most of the BHA’s projects were targeted at elderly housing instead of family units. As the model of financing and implementation of affordable housing changed forms, the scale of projects shrank drastically. Today, a project including 100 units of affordable housing would be considered extremely large - a far cry from the 1,000 unit developments of the past.
Public housing construction in Boston, and in the United States
In Boston, the vast majority of public housing was created in two distinct waves. The first was between 1938 and 1942, and the second between 1949 and 1954. Until the 50s, this chronological distribution of publicly funded dwellings closely mirrors the public housing booms of the United States as a whole.

density The need for concentration? During the first half of the 20th century, the established line of thinking in the planning community was that density was something to avoid. From Ebenezer Howard’s Garden Cities to Le Corbusier’s Ville Radieuse the idea of separating out housing and freeing up wide swaths of open space for singular uses prevailed. In the 1960s Jane Jacobs was a huge influence in turning these notions around. The premise that density is in fact a healthy characteristic of an urban neighborhood was detailed in her seminal work, “The Death And Life of Great American Cities.” Condition 4 in her recipe for vibrant city life states, “The district must have a sufficiently dense concentration of people, for whatever purpose they may be there. This includes people because of residence.” The supposed link between high density and slums or “troubled” areas was shown to be a faulty one based partly on the confusion between density and overcrowding. Overcrowding being the condition of too many people living in a room or dwelling, while density is simply a high concentration of dwellings. It is difficult to identify a “perfect” density when applying this to public housing, as it is just one of many factors contributing to the success or failure of a project or neighborhood. Jacobs pointed out that she had discovered only one city district with urban vitality (by her definition) where density was below 100 dwellings per net residential acre. Most housing projects we have looked at in this
book have considerably lower densities, and many would certainly not be considered failures. Another factor relating to density is the ground coverage of a residential project. This ratio between built-upon land and open land varies noticeably from project to project and the possible permutations are quite numerous. It is possible for a project with low ground coverage to have a high density and the inverse relationship can be found as well.

Density | Site & Building Design 74
Landscape Lessons learned Paradoxically, one of the most important factors in the success or failure of a housing project is not the housing itself, but the quality of the space around it - the landscape. Looking at projects built in the early part of the 20th century, you will notice a priority put on the creation of large, open communal spaces between buildings. What was thought of as an immeasurable resource, in reality, became an affliction upon the community and contributed to the decay of many housing developments. Simply providing a pleasant landscape, it was discovered, does not assure a healthy and successful environment. Closer study into how residents use the space around them has led to better strategies for landscaping and the delineation of space. Architect and planner Oscar Newman was a pioneer in this area, conceiving the now well-established theory of defensible space in the 70s. The theory relies on the correct combination of good design and social attitudes.
As these new ideas and theories took hold, housing authorities began to take a second look at their projects. In Boston, the BHA redeveloped a large portion of its housing, which was seen as a significant improvement to an ailing housing stock. The photos below show Boston’s West Broadway project before and after redevelopment. The figures on the opposite page detail the changes implemented at BHA’s Commonwealth project. Before it was redeveloped, Vale (2002) remarked that Commonwealth’s buildings “had no connection to the outdoor realm, which remained wholly public and alien. After redevelopment, many buildings...carefully considered interrelation with adjacent yards, terraces, and walkways.” New landscaping and re-grading was able to create more clearly defined spaces by which residents could establish a sense of belonging.

Building entry The way in which building entries are addressed is an important part of landscape design whether it is fifty people using a single entry or fifty families using fifty separate entries. Much of this design involves what is called transitional space - the zone that transitions a person between the fully public street or sidewalk and the private dwelling. Symbolic barriers can be used here to inform the user that he/she is moving from a public to a private space and vice versa. Hedges, low fences, changes in ground texture, lighting and open gateways are all useful in creating a perceptible progression from one type of space to another. Individualized entries are often addressed with a change in elevation such as a few steps or a larger stoop. If a change in grade is not possible, other physical barriers can be used to achieve the same effect of creating defensible and well-delineated spaces.
Single, global entry way
Individualized, raised entry ways
Individualized, at-grade entry ways with semi-private zone
In relation to ground-level units Units on the first floor or ground level of a building are usually the most exposed and most susceptible to problems commonly associated with housing projects such as drug activity and other types of crime. When there are no barriers of any kind between the dwelling unit and the exterior public realm, there can be serious psychological and physical consequences leading to deterioration of a residential community. The photo (top right) shows a typical â&#x20AC;&#x153;no mans landâ&#x20AC;? that provides no defensible space and is completely accessible to anyone who would choose to go there. The only landscape is a continuous layer of asphalt. In contrast, the photo below shows a redeveloped project where ground level units have been carefully individualized. There are clear transitions between the public walkway and the private yards created by railings and planters. In a mixed-use project containing both housing and retail, the positioning of shops and restaurants can alleviate the problem of abrupt transitions between the public and private realms. This is especially helpful if the project is located on a street that has limited space for landscape transitions.
Landscape | Site & Building Design 80
Outdoor common spaces Common outdoor spaces have the potential to be great amenities for housing residents. The execution of these spaces has a lot to do with their success or failure. When an outdoor area is completely public with no boundaries or transition zones, it can become an unsafe zone that no one wishes to occupy. Installing transitional zones and symbolic barriers just as you would at a building entry works in the same way to create semi-public or semi-private zones that have an implied sense of ownership attached to them. Well-defined common space Poorly-defined common space
Outdoor private spaces Outdoor spaces that are meant to function as fully private zones need the most physical protection through landscape elements. These zones most frequently take the form of back yards or patios, but can also manifest themselves as front yards or porches. When residents are given control over their own entrances, they will often take the initiative to privatize and personalize them as seen in the bottom photo. The sense of ownership and personal investment in their â&#x20AC;&#x153;stakeâ&#x20AC;? of a larger community is an important factor in a successful project. Landscape | Site & Building Design 82
SITE TyPoLoGIES Examining the housing project at the macro level Many housing projects are of a scale that they become a separate neighborhood unto themselves. This is especially true for developments built in the earlier part of the 20th century. This section is about taking a step back and looking at groupings of public housing at a greater scale. Five different site typologies will be explored and are listed as followed: 1) 2) 3) 4) 5)
Superblock: low-rise Superblock: high-rise Small block: row house Urban infill Small-scale scattered-site
Site Typologies | Site & Building Design 84
Superblock: Low-rise The superblock was a typical site configuration during the first big public housing booms of the 30s, 40s and 50s. Characterized by clusters of zig-zagging low rise buildings, the resulting spatial environment has been called “urban swiss cheese” because of the large gaps in the built fabric. Often times, these projects were first built with very little attention paid to the space between the buildings. These areas were often completely barren, save for a few trees and the occasional piece of playground equipment.

Superblock: High-rise The high rise superblock typology is quite different in that it has not suffered from the same stigma as its low-rise counterpart. While some infamous projects fall into this category (like Pruit-Igoe), success stories like Starrett City in Brooklyn, NY are not uncommon. The efficiency of space created by high rise towers allows for large swaths of open space below. Many times there are no units on the ground floor of the buildings, so different landscaping strategies are used. 6%

Small Block - Row House Consequently, the row house typology as conceived today emphasizes the importance of streets. Dwellings typically face directly toward a public or semi-public street in the classic urban manner. Open spaces are generally narrower and the large blocks of the past are divided into smaller units by more frequent streets.
The row house as a dwelling type has existed for hundreds of years. However, it was not commonly found in public housing until the latter part of the 20th century. When it did start to appear more frequently, it was after the consensus in the architecture/planning community that public housing should generally look the same as private housing. Many public/affordable row house developments today are influenced considerably by the tenants of new urbanism as well as certain ideas from Jane Jacobs’ writing. % 66

Scattered-site housing gained popularity in the latter half of the 20th century and has been tried by most housing authorities. Developed several units at a time, this affordable housing typology has the ability to function in a more strategic manner and is more versatile. The density of the surrounding neighborhood can vary significantly, depending on the context of its placement.

public/private relationships Effects on ownership and units access The way we traditionally look at public and private spatial relationships is to determine whether it has ownership or not. To say that someone is encroaching on one’s property is to imply ownership of a space; to say that someone does not own property is to imply the space is openly accessible to the public. .In regards to housing, “public” spaces are outside the unit and completely accessible to general visitors, while “private” spaces are those inside the unit and access is limited to and controlled by residents. However, aside from these two extremes, there are varying levels or degrees of public and private space depending on the context and specific spatial definers. Here there are six generic ways to look at how spaces are defined based on varying degrees of accessibility, which can be further divided by the perceived or actual barriers to create thresholds between spaces.

Public space surrounds the building, but once past the point of entry, public access is greatly limited. Surveillance from private areas to public areas is generally low. This building type often has actual security in its lobby, as opposed to perceived security created by threshold elements. The site is often limited, but can create higher resident densities on a limited parcel. This limited site, however, affords little outdoor public space, does not create family-friendly space, making it more ideal for elderly or singles housing. The lack of personal defensible space -- inside or out -- often inviting criminal activity. The single entry and lobby space allows for greater security, but once past the point of the lobby, the visitor is allowed contact with nearly every unit in the building.

This relatively efficient type of building has very little security from general public access, and unit access is directly off the point of vertical circulation, allowing no interior community space. Multiple entries serve only a small number of units, allowing closer surveillance over each unit than a tower. However, this also isolates residents from daily interactions within the larger development community. The single entry and lobby space allows for greater security, but once past the point of the lobby, the visitor is allowed contact with nearly every unit in the building. Building layout creates a perceived private-ness through the creation of courtyards between buildings in the development. This, combined with a low structure, creates a minimal amount of defensible space. This community space has only slight implied ownership edged by the surrounding buildings and minimal fencing in the development, but has no true ownership within the development, often allowing the space to go unmaintained. It can be used by any number of people, both residents and non-residents.

With each townhouse having its own unit entry, this provides the most defensible space and control over who has access to the unit. This also creates a unique sense of ownership to each unit and fosters ownership, pride, and respect in one’s space. Townhouse units are stacked for urban efficiency, but share only a “front yard” space, making each unit highly individualized. Open space around the unit is treated as front and back yards, creating both perceived and actual limits to access, using fences and other landscape elements to create thresholds within the entry sequence as well as private and limited-access community/neighborhood space behind the units. Despite having fewer layers of space between the public and private spaces, the subtle thresholds, created by fencing and landscape elements, establish clear owndership of each unit. This building type has a lower density, making it less efficient and less ideal for an urban setting, but also creates a sense of community and neighborliness often not found in the city.

Space & Access Synthesis This diagram shows the distribution of varying types of public and private spaces across the three specific types of public housing developments. It is intended to establish the majority of gradient (in terms of public and private) to better define which types of spaces are used more often, and the effects this has on varying types of social and functional scenarios. For example, the single and/or double loaded corridor type has fewer instances of thresholds and greater expanses of interior public space that serve as a longer transition of public to private. Conversely the individual access building type has more frequent instances of thresholds that serve to buffer the private realm of the unit from the public realm of the street and pedestrian traffic. The point loaded access type essentially incorporates a mix of the two previous types in that the thresholds that define the public and private spaces are more uniformly divided throughout the development.

Point Loaded 1930-1960 Interlocking L In this plan type there are a series of “L” shaped units that interlock with one another. In most cases, two “L” shaped units are paired together, which then share a circulation core with another pair or singular larger unit. These four units per floor share a singular central core which was allowable by code standards in the 30’s. The aggregation of these interlocking “L” shapes created the very popular zigzag pattern associated with housing designed directly following the Great Depression.

Point Loaded 1930-1960 Cross and Bar In the cross scheme, four rectangular units are attached to a central core. In this unique configuration, each unit has three facades that are exposed. This condition allows each room to have at least one wall of windows, and two rooms to occur in corners with two walls of windows. In this configuration even the bathrooms and kitchens have windows, and ample amounts of light. Even in the bar configuration, the units are fairly shallow and allow ample amounts of light and air to circulation through the unit.

Corridor Access 1960-1980 Double Loaded Corridor In the typical double loaded corridor strategy, the floors will have between six and twelve units organized along a central corridor. This plan is the most typical, and is the most widely used plan in low income housing because of its high efficiency. However, the corridor becomes a long and narrow space with no windows and no natural light. The units themselves only have one exterior facing wall and leave several of the rooms against the interior facing wall. As a result, in most double loaded corridor plans the living room and two bedrooms are placed to the exterior and the kitchen, while bathrooms are tucked between those spaces and the corridor.

With an exterior corridor, the rooms which were previously tucked into the space between the living room and the corridor now have the capability of having natural light with the exterior corridor facing wall.

The skip stop is a unique take on the double loaded corridor configuration where units become duplexes, that occupy two floors, allowing one floor to span the entire width of the building. This allows some floors to be free of public circulation. It also allows units to have more than one exterior facing wall. However, it means that most unit plans have internal circulation which subtract from usable space.

With the overall goal of keeping tenants in these units for a longer time, they have become more singular and identifiable. This gives the tenants ownership and pride. Most units have their own private entry and circulation, and if they do not, they typically only share vertical circulation with one other unit.

Although townhouses are most popular today in the individual access phase, the efficiency of the double loaded corridor type cannot be ignored. It is one of few types still common today, and has found ways to cater to the needs of the individual. In some cases, units actually have their own private door, and the indoor corridor ciruclation becomes a secondary circulation. Second floor units are then allowed to have exterior balconies that give the tenant their own private space and sense of ownership.

Bathrooms Generally, bathrooms don’t significantly increase in size, but they do increase in quantity. We can see that there was a slight increase in size from the earliest phase to the second phase, but both average to be about 42 SF. However, when we reach the last phase, the square footages of individual bathrooms jump to 50 SF. When there are two bathrooms in one unit they tend to be smaller, and when there is one bathroom they tend to be larger.

Overview This section will compare and contrast the efficiency of four projects, located in the precedents section, that cover four separate time periods in public housing history. The analysis uses three different scales, site, building, and unit. Collection of data is compiled into a series of spreadsheets and then presented through charts and diagrams. What will these findings tell us about public housing building efficiency and how it has evolved for better or worse over time? A percentage for “poche” space is added to the total NASF. Poche space is the area needed for walls, mechanical, electrical and telephone equipment, wall thickness, and public toilets at the building level. Building efficiency is the ratio of NASF to gross square feet (GSF), the total area including the NASF and poche areas. Building efficiency equals NASF/GSF.
When calculating individual unit efficiency, the four surveyed plans are all two-bedroom and one bath units. You will notice that some space within an unit is considered circulation, even though it is not delineated with walls. We call this circulation “implied corridor.” Each section has an accompanying graph with its key shaded across the array and highlighted in green for the focused scale. The project is placed on the graph according to a ‘baseline’ derived from the averages of the selected projects plus two others from the precedent section in this book.

An architect can plan for either a single-story building consuming the entire allowable area in one floor, or a multi-story building that rises higher above the plane of the land, but which must consequently result in a smaller footprint than would a single-story building of the same total floor area. By combining the horizontal and vertical limits into a single figure, some flexibility is permitted in building design, while achieving a hard limit on at least one measure of overall size. One advantage to fixing this parameter, as opposed to others such as height, width, or length, is that floor area correlates well with other considerations relevant to zoning regulation, such as total parking that would be required for an office building, total number of units that might be available for residential use, total load on municipal services, etc. The amounts of these things tend to be constant for a given total floor area, regardless of how that area is distributed horizontally and vertically. Thus, many jurisdictions have found it unnecessary to include hard height limitations when using floor area ratio calculations. To determine the efficiency ratio of an existing plan this equation is used when the amount of affordable gross area, based on available funds, is known, and it is necessary to determine the maximum amount of net assignable area affordable. This is especially important in public housing and must be consistent with successful models. These buildings should be as efficient as possible, therefore the ratio should be higher than the typical market-rate housing development.

Site Efficiency It should be noted that no two projects are ever BASELINE alike, even if the density or FAR are identical. NO CORRIDOR LIVEABLE DOOR-SWINGS Buildings of equal FAR, for example, can have significant differences in appearance depending on the site, landscaping and architecture. The same is true of projects with an equal number of dwelling units per acre. ‘Building Coverage’ is simply all building footprints divided by the gross site SF.

Unit Efficiency At this scale, efficiency is measured through a series of subtractions from the overall internal Net/ Gross calculation. The ‘no corridors’ F.A.R. BLDG COVER NET/ GROSS SURFACE : FLR WIN : UNIT UNIT/ ACRE measurement subtracts the implied and actual corridors from all of the ‘leasable’ space. The ‘liveable’ space percentage is simply all bedrooms, kitchen and baths Net/ Gross, without storage. The final calculation, ‘door swings,’ subtracts the square footage of any door swing into livable space. This net is then divided to the internal gross.

Conclusion Its has been noted that the allowable FAR has a major impact on the value of the land. So in turn, higher allowable FAR yields higher land value. We can see that Starrett City has the highest FAR because it consists of mostly 15-20 story buildings while the other projects are much smaller in scale at 3-7 stories. FAR, a poor predictor of physical form, should not be used when the objective is to conserve and enhance neighborhood character. Whereas traditional design standards (height, lot coverage and setbacks or build-to lines) enable anyone to make reasonably accurate predictions, recognize violations, and feel secure in their investment decisions. Assembled lots have a considerable advantage over individual lots, which has a negative effect on fine grained cities and the diversity of ownership. At the building scale we can see a clear delineation based on building type. The two double-loaded corridor building floors yielded a lower Net/Gross ratio and happen to have a higher surface area to floor area ratio. Does this finding prove it to be a less efficient design? It might. Maverick Landing also offers the least amount of windows per gross floor area. Bromley yielded the highest Net/ Gross on the unit scale. The actual corridor in this project is central to the plan with livable spaces surrounding it.

Building Operations and management The management of affordable housing encompasses a variety of tasks initializing with design development and continuing through the long-term habitation of the building. As the Boston Housing Authority suggests, a managing party must: â&#x20AC;&#x153;Provide stable, quality affordable housing for low and moderate income persons; Deliver these services with integrity and mutual accountability. Create living environments which serve as a catalysts for the transformation from dependency to economic self-sufficiency.â&#x20AC;? These requirements are provided through a variety of management types including: . - Self management . - Fee management . - Cooperative management When commencing the design process, the designer must address the management type, as it will inform the allowable costs as well as the programmatic necessity for additional office and/or maintenance program on-site. Fee-management is the most frequently used management style; as it allows large companies to run efficiently, do to a higher volume of housing units and properties. Through a consolidation of management activities, private companies are able to provide cost-effective management of housing infrastructure. This being said, some residents prefer to be self managed [i.e. Tent City, Boston], as it gives the residents more control within the decision-making process while also localizing social program opportunities. Although this type of management tends to be
less cost effective then private management, this approach is valuable in its ability to appease large groups of residents in a democratic way. Regardless of management type, managed properties require the same attentiveness to detail and prompt service. Another key aspect of building management is frequent maintenance, which keeps the building functioning and performing the way it did when it was originally constructed. Maintenance requires attention to detail in the initial design phases as well as rapid response during building habitation. During the design process frequent meetings are held between the contractor, architect and management staff to flesh out problematic areas of the design and come to functional design solutions. Since maintenance is a continual process over the lifetime of the project, it is advantageous to plan long term to save additional costs in the future. Building maintenance is of the utmost importance, as it must happen before management can provide additional services to residents. Although some maintenance issues are not perceived until after the building is completed, the fewer problems the better. The design team and management staff have the ability to prevent the majority of building issues, if they thoroughly understand them. Within this section the following building operations issues will be discussed: . - Curb Appeal . - Chronic Issues . - Winter, Water and Teenagers . - Expert Interviews Verbatim
curb Appeal as catalyst Positive design outcomes are not just about financial stability or housing the largest number of people, but are also about providing a positive and stable quality of life. Catalysts for these types of outcomes are primarily shaped by the buildings designer and thus lie in the realm of architecture. To design affordable housing that is easily managed, the most emphasis should be applied to curb appeal. Curb appeal is the first priority of the designer and developer at the onset of a project, as it produces a property that is easier to maintain over the long term. By designing a building that incorporates interesting and varied public greenscapes, various urban implementations and localized community spaces, public and affordable housing can effectively blend with current housing stock. This blending creates an environment that is no different than its surrounding context, thus preventing negative stigmas and localized crime. A property that has lower crime and is not perceived as public or affordable housing becomes one that is easier to maintain and allows those managing to focus more on improving the resident experience. The upfront cost of architectural and landscape implementations has the ability to improve the properties value, while also improving its ability to serve as a catalyst for improved social cohesiveness. Curb appeal is important in any project, especially in family housing, and can be improved though the addition of park space, playgrounds, landscaping, community centers and visual vistas.

chronic issues Through conversations with various subject experts, a series of chronic issues were brought forward; that have plagued public and affordable housing durability in the past. Due to their detrimental impact these chronic issues should be addressed in all current and future public and affordable housing developments to prevent compromised construction. These chronic issues are primarily due to the tight budget constraints associated with these types of projects, stemming from designer and contractor cost cutting. Although not all chronic issues are related to poor design and construction techniques, the vast majority of them fall within this realm. Through a thorough understanding of buildings materials and past chronic issues, a designer can make educated decisions on the implementation of particular materials. To remedy some of these concerns, public and affordable housing projects, within the Boston context, have been employing particular materials consistently. Affordable housing frequently employs vinyl, modern brick veneer or hardi-plank siding to solve envelope and moisture concerns; As well as wood or aluminum frame construction for interior partitions and exterior structural conditions to maximize future adaptability. Although each material has various positive and negative attributes, it is important to balance the overall performance of a material with its cost and aesthetic desirability. The following chronic issues discussed are: - Brick Veneer Construction - Concrete Masonry Unit Construction - Cavity Structural Brick Construction
chronic issue: Brick Veneer Exterior envelopes in mid-rise buildings built before the 1980â&#x20AC;&#x2122;s utilized brick veneer that was not fully understood at the time, leading to chronic moisture issues. Although the majority of these buildings were built codecompliant, the reality was that many of the requirements were improbable to meet. Brick veneer construction acts in a similar way to the exterior brick face of structural brick construction, in that it sheds precipitation on the exterior. Moisture that makes it through the brick veneer, reaches a one-inch minimum cavity condition, which under optimal conditions would allow moisture to evacuate the cavity through weep holes at the base. Various brick ties bridge the one-inch gap to attach the veneer to the wall sheathing that is often exposure-one plywood infrequently covered in a weather resistant membrane. It turns out that this code required one-inch gap is difficult to acquire due to the accumulation of mortar droppings on top of the brick ties, as well as the accumulation of construction debris within the cavity. This compromised gap produces liquid water bridging to the interior face, which by code is only required to prevent water vapor, not standing water from passing through. This transmission of precipitation from exterior to interior causes various interior wall cavity issues, including but not limited to: - Mold - Structural Damage - Wall Tie Corrosion - Interior Gypsum Damage - Veneer Separation Building operations & Management i Management 182
chronic issue: concrete Masonry unit Concrete masonry unit [CMU] construction is often utilized in residential foundations and frequently in above ground applications in southern climates. CMU construction when used in structural applications is limited by its seismic and wind intolerance, as well as its approximately 35 foot height constraints. Bearing walls are also required to be at a minimum, six-inch solid CMU or eight-inch hollow CMU construction, and when above a single story, vertical rebar is required every 32 inches on center. These limitations are also coupled with frequent CMU cracking and the difficulty of moisture and acoustic control. These issues have the potential to cause expensive and time-consuming management considerations over the long term. Although original construction costs are often much lower then other building types, many issues during building modernization renovations and/or reconfiguration arise, causing increased costs. When renovating a CMU constructed building that utilizes vertical rebar, extra time and care must be used to remove and redistribute partitions. Interior partitions also require additional furring strips or narrow stud walls to provide gypsum surfaces [and electrical and service connections], bringing the total wall thickness far above that of a typical wood framed structure. Issues associated with CMU construction include but not limited to: - Large Wall Thickness - Moisture and Acoustic Transmission - Difficulty of Renovation
chronic issue: cavity Structural Brick Brick construction has been used by builders for thousands of years, but in the last few hundred a switch has been made to cavity wall brick construction that under ideal circumstances provides a watertight building envelope. Unlike conventional brick construction, cavity brick construction provides two parallel brick structural walls with a one-inch minimum cavity condition, which under optimal conditions would allow moisture to evacuate the cavity through weep holes at the base. Various brick ties bridge the one-inch gap to attach the exterior brick wall condition to the interior brick wall condition. Much like the brick veneer wall condition [mentioned previously], this water evacuation gap is difficult to acquire due to the accumulation of mortar droppings on top of the brick ties, as well as the accumulation of construction debris within the cavity. Standing water created by these obstructions is allowed to penetrate into the interior causing similar brick veneer problems [i.e. mold and rot]. This water penetration also causes the expulsion of mortar efflorescence, which is the release of mineral compounds onto the face of the brick. Brick efflorescence, although aesthetically displeasing isnâ&#x20AC;&#x2122;t damaging itself, but is the precursor to greater problems such as Brick spalling or cracking. Brick spalling is the destruction of a bricks surface via freeze/ thaw cycles, which compromises its structural integrity.

Maintenance: Winter When the temperature dips below freezing, there are many dangerous and problematic issues that face a building manager. The most important issues to focus on are: - Shoveling of Walkways - Frozen Pipes and Utilities - Roof Ice Damming - Icicles and Roof Avalanches
Maintenance: Water Water damage is perhaps the most damaging of any maintenance issue. Moisture and standing water can ruin interior finishes, wall components and occupant belongings. The most important issues to focus on are: - Proper Site Drainage - Adequate Gutter System - Parking Lot and Plaza Drainage
Maintenance: teenagers Most affordable housing is designated for family use, and thus is more expensive to maintain then typical housing. This additional expense is due to higher maintenance costs within households with one or more teenagers. The most important issues to focus on are: - Gypsum Damage - Door Stops or Bumpers
Expert Interviews Verbatim “What do you think is the most important focus of designing affordable housing?” - “Quality design with the intended user in mind, and long-range focus on the quality of the asset.” - “Understanding the needs of residents and management staff.” “What issues pose the most concern when managing a project?” - “This depends greatly on the project and the location. In general, energy efficiency, security, marketability, and curb appeal.” - “Understanding conditions of the project. Personal safety, building deficiencies for example. The things that affect the day-to-day lives of the tenants.” “What role does maintenance play in day-to-day management?” .- “Maintenance issues are central to providing stable, quality housing.” - “It is the first thing that must happen, before anything else can be done properly.” - “Winter. Water. Teenagers.” “How much does damage or neglect play into future material choices?” .- “Central to our process, we meet with maintenance staff and often do a review of work orders to better understand how and where materials have failed in earlier design efforts.” - “I think the industry has been through enough cycles now to consistently incorporate durable and energy efficient materials to the greatest extent possible.”
“Are there particular strategies that have proven to be unsuccessful?” - “Typically the desire to rush toward a design solution, as in developing plans in response to ‘shovel ready’ initiatives, have been less successful than those which have had time to be thoughtfully considered.” - “Self-management. The subsidized housing world is too regulated to have a small management company succeed and be efficient, particularly in Boston.” “What role does unit occupant type play in building durability?” .- “Rental housing, particularly family subsidized housing, is subjected to considerable heavy use, sometimes abuse, and it must be factored into the design and material replacement reserves.” “Are there chronic problems that face maintenance and durability?” - “Exterior envelopes of mid-rise buildings typically constructed before 1980, when veneer masonry design was less well understood. Before 1950 for low-rise buildings when solid masonry was used. Both have been problematic.” “Is Public or private management more or less efficient?” .- “Privately managed projects have different labor costs than our publicly managed projects, so many efficiencies may be possible.” - “There seems to remain quite a bit of waste in the public housing operations system.”
“What role does durability play in initial design?” .- “For family housing, it is extremely important. Materials are selected for their durability whenever possible, although sometimes we can’t afford the best.” - “It’s very important. These issues are built into our design contracts as requirements for building specifications.” “How do tasks such as trash collection or laundry influence design decisions?” .- “These are very influential for our modernization projects and less influential for more modest capital improvement projects.” “Are there any management strategies that prove more helpful then others?” - “Private ownership coupled with HOPE VI status, provides some relief from public housing tenant selection procedures and income qualifying levels resulting in a somewhat more economically diverse community.” “How much does cost factor into management strategies?” .- “Affordable housing projects are resource constrained, so cost matters both in terms of initial costs and operational cost down the line post occupancy.” - “Overall management costs are very, very important, from maintenance to utilities.”

Occupant Type Considerations Occupant type plays a large role in overall building durability, maintenance and management; due to the heavy use [and abuse] of family subsidized housing. Within the realm of affordable housing, the majority of the demand is for family housing [i.e. units larger then one bedroom], causing a disagreement between market demand and ideal developer supply. This discrepancy in market supply and market demand, relates directly to the relationship between the two primary entities in affordable housing: - The Funder [government entity] - The Developer [private entity] The entity funding a project wants to provide the needs of the low to moderate income residents, which in most cases [including Boston] suggests a higher rate of family housing. Larger three and four-bedroom units are necessary to meet the demands of housing large families, and thus funders often require these within a project. Although these needs are not always the most cost effective solution, they are a necessity. Housing for families with children, tend to require the most unit maintenance. Thus buildings with large family rental units should provide additional funds within a projects replacement reserve. This fact deters project developers, as larger units create fund deficiencies in relation to other unit types. Smaller units with no children require the least maintenance, and are the most cost effective. With these ideas in mind, unit diversity is not only a way to satisfy market demand, but also a way to subsidies large family unit maintenance requirements.

Cost and Assessment In order to provide a sufficient quantity of affordable housing units, while at the same time providing quality unit environments, building cost assessments must be made to maximize the overall project success. Before building design commences, a site must be picked that acknowledges cost restraints, while also balancing the need to provide easy access to locations of commerce, employment and education. Access to these programs, provides the ability for residents of affordable housing to easily access the citiesâ&#x20AC;&#x2122; amenities. Along with these adjacent programs, the site must provide easy access to transportation infrastructure, such as subway stations, bus stops or automobile parking. An ease of transportation will allow residents to find work, and thus elevate low-income residents from poverty. After a site has been picked acknowledging location and transportation, density must be assessed to provide a balance of unit quantity with unit size and access to green and public space. These three topics must be addressed, before the designer can even begin designing a physical building. If possible, the designer should be involved at the site selection phase, to guarantee the best possible location for a future affordable housing project. Although many inner cities have few sites that are within the reach of low budget affordable housing projects, investigating all possible locations will assure a projects success. These evaluations although not specific to affordable housing impact this residential type to a greater
degree, due to opposing forces within the selection of a site. Even though overall cost plays a large part in site selection, a lower cost building placed in a more expensive and ideal site can harbor greater socioeconomic outcomes for its residents. This rational is the complete opposite of past affordable housing procedures, in that old sites were often chosen for their cheapness rather then their ability to empower residents. The quantity versus quality argument is one that plagues the ideology of affordable housing, and is best noted in past affordable housing high-rise units. Although a large number of units were supplied, there overall effectiveness on stability and/or upward mobility was non-existent. These inhospitable buildings were eventually torn down, representing not only failed policies and design, but also an utter lack of location, transportation or density assessments. Contemporary solutions to affordable housing although more expensive in hard construction costs, are much more successful in aiding their residents to become stable and provide needed services. A balance must be struck between cost, location, transportation and density, which harbor a positive and stable environment for its residents. Due to funding deficiencies, affordable housing needs proper cost assessments, which will be discussed in depth. The most important issues to focus on are: . -Location Assessments . -Transportation Assessments . -Density Assessments

Location poses an extremely problematic issue, as affordable housing by nature wants to be located near urban centers, commercial [c] employment [e] and academic amenities [a]. Due to the high cost of land it is often difficult to find a quality site within a projects budget restraints. Finding a site that falls within these cost constraints, while also providing easy access to amenities and employment opportunities is the most difficult portion of the pre-design phase. Successful projects should find equilibrium between the least costly site, and best possible location. Building location is also problematic in urban context where land is often only available under three pretenses: - City-Owned Disposition - “Un” Developable - Inclusionary Zoning Land owned by the municipality has potential depending on the properties location. A developer, at lower then market rate, can acquire City land as long as affordable housing is maintained. Land with no market value, although typically the largest quantity of available land, is generally unfit for affordable housing developments. This land with no market rate is typically located on the fringe away from job and urban centers putting residents in a state of perpetual poverty. Land acquired with the intent of mixed income development is typically located in ideal locations, as market rate units “subsidize” the overall cost. Proximity to employment and amenity hubs often depends on a balance of market-rate and affordable housing stock.

Transportation is also an extremely important concept when discussing affordable housing. With the need to travel to employment opportunities, public transportation or automobile infrastructure becomes necessary to provide a catalyst for residents to change from dependency to self-sufficiency. Through the development of a site, automobile parking [p], bus transit [b] and subway transit [s] should be utilized to provide maximum mobility to residents. Although vacant sites located adjacent to transit corridors do not appear in many urban contexts, projects that due locate such a property should anticipate extra land costs. Public transit adjacent properties may have additional costs, but compared to the cost of building and maintaining parking infrastructure, itâ&#x20AC;&#x2122;s comparatively minor. When analyzing transportation with regards to site selection, it is extremly important to address the following transportation topics: - Overall Convenience - Variety of service - Variety of destinations Affordable housing that only utilize automobile infrastructure has a tendency of burdening residents, as automobile ownership adds additional costs to residents already marginalized by economic hardship. If property with transit connectivity is unavailable, consider the potential of rerouting existing transit routes to tie into the project. When selecting a site, adjacent transportation infrastructure increases the overall success of the project, regardless of added costs.
density Assessment Density within neighborhood contexts has been linked to the creation of tight knit communities within affordable housing. Density has also been viewed in a negative light, in previous affordable housing conditions where density lead to concentrated poverty and the decline of neighborhoods. Striking the precise balance of density, allows the designer to create a safe and comfortable environment for the residents, while maintaining cost efficiency standards for the developer. Maintaining public space and utilizing low-density [l], medium-density [m] and high-density [h] buildings, creates a varied and comfortable neighborhood that serves as a catalyst for increases socioeconomic status. A mixture of greenscape and hardscape also aids generally in the other missions of affordable housing, through a combination of varied exterior spaces. Although oversized units and expanses of open exterior spaces do produce comfortable living environments, unit inefficiency, due to low-density, also has negative attributes as this adds to overall project costs. When analyzing density, it is important to apply emphasis to: - Variety of Density - Variety of Exterior Spaces - Respect Existing Density When designing affordable housing, proper density can provide a cohesive and communal environment that instills residents with a sense of place and neighborhood. Affordable housing that encourages communal activities and sense of community leads to a successful and easily maintained housing development.

Crime prevention and security Security is one of the primary problems for public housing. For many years, policy makers and architects have tried to find solutions to these problems. However, these problems are very hard to eradicate this situation, but architects have found some ways to reduce crime. These ways which emphasize the proper design and effective use of a created environment are called â&#x20AC;&#x153;Crime Prevention through Environmental Designâ&#x20AC;? (CPTED).
Where are the crime prone areas?

Crime Prevent through Environmental Design There are many places in public housing communities that crime event will occur. However, most places, where crime events occur, can be transformed into safety areas through the environmental design. The cause of public housing crime is separated into two parts, social and physical feature. For physical part, this is the part that we architects can improve. The lack of surveillance, the lack of access control, the lack of clearly defined access and physical facilities, etc, these things will be better if we make a better environmental design.

Tent City and Camfield Gardens which are using all three strategies did have fewer crime report than the other two examples. However, Tent City is mixedincome public housing. So, the resident who lives in public housing also can be a factor that influence the crime rate.

CPTED in Parking Area The major place where has most crime reports is the parking place. Here are two examples, Lenox and Camfield Gardens. They are neighboring communities. But the number of crime reports are completely different. The different is that Lenoxâ&#x20AC;&#x2122;s parking area is a public place, and none of CPTED strategies are used for design its parking place. However, Camfield Gardens uses CPTED strategies to make parking place to be a semi-private place. That reduces the likelihood of crime. However, for some parking places only using the CPTED strategies as a passive system is

FINANCING Pro-formas and Prediction
pro-formas and prediction Learning From a Pro-Forma Financing a housing project begins with a pro-forma, a budget that tries to predict costs and funds during the development of a project, as well as incomes and expenses after the project is built. It is a way to anticipate how big a project can be and what the major obstacles are. We will look at subsidized housing (privately owned) since it is more common than public housing today. Subsidized housing begins with a land and sometimes building acquisition. The bank offers to loan a certain amount of cash up front to acquire land and cover construction costs, and in exchange the developer pays interest on the loan. Once the development phase is completed and the project is occupied, the loan converts to a permanent amortizing loan. More funding for the project is acquired via equity, tax credits and government subsidies. Investors can pay cash up front for a long term tax credit (an incentive from the government for investing in affordable housing) and the developer gets cash up front to help cover development costs. After land acquisition and funding, the pro-forma looks at all the hard costs (construction) and soft costs (everything else) involved in the project. Hard costs include calculations for materials and construction labor and generally comprise the bulk of expenses (outside of acquisition) in a new development. Soft costs include fees for
various parties. Architects and engineers typically are paid 4-6% of total hard costs. Surveyors, environmental engineers, and clerk of the works are other important costs on the design side. Legal fees, taxes, marketing, insurance, appraisals, construction loan interest and loan fees are other important soft costs. Finally, a contingency must be set in place for each of these parties, to prepare for any unforeseen costs (to cover a margin of error). The pro-forma also tries to predict the financing that comes after a project is built, the operating costs and incomes. Sources of income include tenant rent, parking fees and any commercial rent that may be in a project. Expenses include utilities, maintenance, janitors and other operating costs. Net Operating Income (NOI) is the final calculation of these costs and determines how much the owner may be able to borrow.
