GIVING BACK

• HOUSING THE OTHER HALF • DIY meets the LIVING BUILDING CHALLENGE • TRANSITION TO PRACTICE Graduate concentration application: Sustainable Design

HOUSING THE OTHER HALF

50% of the world population lives in villages. The world population is predicted to stabilize at 9 billion. At least 4/5ths of these people are poorer than you. They will never afford architects for their housing. Let’s apply design thinking for the economic bottom 1/5. Much attention has been placed on the process of urbanization, but an equal and relatively unaddressed need is in the rural settlements where the poorest people still live. As resources are stressed in the 21st century with 9 billion inhabitants, and having passed “peak oil,” predictions are that urbanization will be partially reversed as people need to grow more food locally.

DIY meets the LIVING BUILDING CHALLENGE (beyond LEED)

Most people on the planet build their own houses. What if architects created systems for self-building that were beautiful, frugal, and environmentally effective? What if instead of a single building you could design a way of building that people themselves could replicate thousands of times? The Living Building Challenge is the new standard in sustainable design that embraces “regional solutions and respond to a number of variables, including climate factors and cultural characteristics.” It is more radical than the more commercialized LEED, “no points, all pre- requisites” with “nature as the ultimate measuring stick of performance.”

Transition to Practice

This includes two themes: “developing the whole architect” and “buildable ideals.” Developing the whole architect means addressing the current practice realities of collaboration and communication skills, along with working in different cultural contexts. We will work via digital exchange with design students in four “countries” for projects set in the four situations: China, India, Mexico, and Mississippi. Buildable ideals means creating a transition to practice by grounding the idealism of design school (in this case housing for the poor) with the groundedness of design carried out through to the details and verified structurally, materially, and with computer energy models and other quantitative tools of practice--just like in the “real” world. Good ideas are easy; good buildable ideas, difficult. This class should appeal to those who are committed to making a contribution with their craft and to those who can see themselves as young architects ready for the world, no longer mere students.

Phase 1: Research and Analysis

Phase 1: Research and Analysis

International Studio Phases Explained

Team Structure: Teams formed within each studio to research precedents and develop site analysis for the local site.

Adam + Forrest + Sam

The studio was quickly divided into four teams at the beginning of the semester to head up semester management, communication, seismic research, and demographic research. The semester management team was tasked with laying out the semester calendar to coordinate work among India, Mexico, and USA. The plan divided the semester into three (3) phases. The first phase would be used by each studio in each country to establish research and analysis of local precedent and possible sites. For the second phase, each selected site in each country would have two teams of approximately six (6) students each (two [2] students from each country). This phase would be for creating a foundation of moves and research for the project culminating in a schematic test of the ideas. Upon completion of the second phase, the teams would then swap projects with another team in another country. Whereby, each team is now working with another team’s project in a new country/site.

The remainder of the semester would be the third phase. The teams would then fully investigate, develop and detail the schemes given to them. The intent of this three phase process is to create the ability to work on multiple sites and projects while also having teammates from that country to easily answer questions. Team TIM (Tennessee India Mexico), as we began to call our international studio, had to shift plans when Mexico was given a great opportunity to work on a project they might actually construct. Therefore, by the end of phase one, the teams were created between India and the USA only. After the second phase, it was determined that most students did not what to switch projects and thought it would be most beneficial to continue investigating what had already been started. This is how the phasing of the semester was imagined and alternatively carried out.

Phase Objectives: Each studio provide local research and information for the site located in their country Each studio provide 3 domestic and 3 international precedent studies

Much effort was put forth to establish effective and timely communications with the other studios. Knoxville [USA EST] is 10.5 hours behind India Standard Time [IST] when not on daylight savings time. This proved a legistical challenge but a great learning experience.

Phase 1

We planned to use technology and programs we had in common to best communicate. Skype was used for conferences and reviews. We created three Tumblr blogs as a way of posting culturally relevant activities that were taking place as well as our work in process. We used it as a platform to post work, in different media forms, to ask questions that could be viewed and answered at India’s convenience. A YouTube channel allowed for initial introductions by each student and faculty apart of team TIM. Google Calendar held our multi-studio schedule. Each studio posted review dates, holidays, video conferences, and other important timing events. Box and Dropbox are online data

storage and sharing sites that we used extensively to share information, documents, and important files. Even with this spectrum of communicating technology, much, if not most, communication happened via email. Every team emailed their foreign counterparts to attempt collaboration and streamline understanding cultural differences and architectural practices. Some teams also used the iPhone application WhatsApp as a mode of texting internationally, which is very popular in India. While this was a full studio for the students in the USA, it was only an elective for students in India. This course and collaboration took place in addition to their studio coursework. As a result not all groups had successful communication with their teammates abroad. However, there we learned a lot about their cultural background from the interaction we had with those students who fully participated.

Seismic Research

Therefore it is advisable to enlarge the section at this corner, shown in Figs. 6-8 and 6-9. Fig. 612 shows different proposals for plans utilizing angular elements.

Emily Dent + Sarah Howell + Tyler Puryear

When it comes to seismic design, materials are one of the first things to be considered. With masonry, there are some general strategies (as seen in the diagrams on the right) that are used to help reinforce the walls. The main focus of this research thus became how to design the shape of the building in such a way that the masonry could provide stabilization on its own. A simple solution for stabilizing masonry (including rammed earth or adobe brick) walls of a lesser thickness is to design them in the shapes seen in figures 6-8 and 6-9. These types of corner solutions provide a more stabilized wall system. If the wall is 30 cm thick, for example, then the free ends of the elements should not be longer than 3/4 and not shorter than 1/3 of their height, as seen in figure 6-6. This minimal length is necessary to transfer the loads diagonally to the foundation. If the angle is well fixed on the bottom to the foundation and on the top to a ring beam, it can be larger or higher. Regardless, the height should not be more than 8 times the width of the wall.

To improve lateral stability the joint of two elements should be formed with tongue and groove, see Fig. 6-10. However, in order to obtain a more flexible structure, elements with shorter length and no tongue and groove joint should be used (Fig. 6-11), if the elements are well linked to a ring beam above and to a plinth below. This kind of solution is used in the project described in chapter 6.4.

The forces perpendicular to the wall are transferred into the angle of the corner. This means it is transferred instead of creating a stress concentration at the inner corner of the angle (figure 6-8). Therefore, it is advisable to enlarge the section at this corner, shown in figure 6-8 and 6-9. To improve lateral stability, the joint of two elements should be formed with tongue and groove. However in order to obtain a more flexible structure, el6-5 shorter Wall elements by their shape ements with length stabilized and no tongue and groove joint can be used. These can only be used though if the elements are well linked to a ring beam above and to a foundation below.

Another factor to consider is the where the center of mass and the center of resistance are located, as can be seen in figure 6-18. The closer the center of resistance is to the center of mass, then the less impact the earthquake will have on the building. In figure 6-18, the center of resistance is not close to the center of mass, thus the dotted lines shows the torque response.

Luckily, all three sites were located in the low to mid range of the scales. This led us to conclude that a construction method that is widely used (masonry and adobe block construction) would be acceptable for each of the sites.

The following are a series of seismic maps of the United States, India, and Mexico. Each map indicates which seismic zone each of the sites is located in.

In the United States, the Tennessee site is located in one of the lower seismic areas, which means any form of construction (masonry, wood, etc.) would be acceptable. In Mexico and India, the sites are slightly more active. In addition to this, these two countries have very limited resources, which means that masonry (and adobe blocks) may be the better choice for construction since they can be locally produced.

Analysis Contents History City Context Local Context Site Drawings

As early as 1800, settlers inhabited the area south of the river near the growing city of Knoxville. The area remained sparsely populated until after the Civil War when multiple bridges were established to provide better access to areas of Knoxville and promote an increase in industrial development. The place named “Vestal” was created by the Vestal Lumber and Manufacturing Company, which was established in the 1880s. With railroad connecting to its lumber yards, the company created hundreds of jobs, resulting in a rapid expansion of the area’s population. A “company town,” based upon the operations of the lumber mill developed near Maryville Pike and Ogle Avenue, and became the focus of commercial and church development. The lumber company became one of the South’s largest, but declined in the mid-20th century and closed in 1963. As the population of Vestal was rapidly growing at the end of the 19th century, Vestal was briefly incorporated as the City of South Knoxville. As bridges and rail lines opened access to Vestal, more commercial and industrial activities were

Much of Vestal was eventually added to the city of Knoxville in 1917 as larger industries became established in the area. One of those industries was the Candoro Marble Company. Founded in 1914 by John J. Craig, III and three business partners, the Candoro Marble Company Showroom and Garage was built in 1923. It was designed by Charles Barber, a prominent Knoxville architect and is listed on the National Register of Historic Places. The company provided Tennessee marble for the construction of many monumental buildings in the eastern United States.

Phase 1

John J. Craig, III led Candoro Marble Company to emerge as the country’s leading producer ofTennessee pink marble and one of the largest importers of marble in the United States. Marble carvings produced by Candoro Marble Company appear in prominent buildings of Washington D.C., New York City, and locally in the downtown Post Office building. The town of Vestal served as a self-contained community with an ice cream shop, grocery, dry cleaners, and many other businesses that provided employment and services for the area’s residents through much of the beginning of the 20th century. Since the 1960s, as key industrial and commercial businesses closed or moved out of the area, Vestal has experienced a slow and steady decline in population and new investments in the community.

City Context

City Information

City Context

Vestal is a small community/neighborhood in South Knoxville. Vestal has an area of only 1.5 square miles; Knoxville’s overall area is 98 square miles. Vestal’s population is approximately 3,000; Knoxville’s total population is around 180,000. Vestal (and South Knoxville) are separated from the rest of Knoxville by the Tennessee River. However, it is just a short drive (5 minutes) from Vestal to downtown Knoxville. The Vestal community is located off of Chapman Highway, a busy main road that goes through South Knoxville; the highway connects Knoxville to the city of Sevierville and the Great Smoky Mountains National Park. Located nearby is Fort Dickerson, a fort that was used to protect Knoxville during the American Civil War in the 1860s. In addition to cars, the Vestal community has a connection to the rest of Knoxville through the use of the Knoxville Area Transit (KAT) buses. Most of the residents’ amenities are found along Chapman Highway or are in downtown Knoxville; there are not many within Vestal.

Local Context

There are two sites chosen for development in Vestal’s local community. Each of these sites provides their own challenges yet they each have the potential to provide back to the local community. The first site (130 Ogle Avenue) is located within the Vestal town center just Southwest of the town’s main intersection. It has direct access to local shops and creeks. There is a local restaurant within immediate walking distance of the site as well as a church across the road. The second site (311 West Young High) is located only a few minutes walking distance East from the town center. It is a little more isolated than the first site but it has an advantage by being located directly between Vestal’s center and a major grocery market further East of the site.

Site Information

130 Ogle Avenue and 311 West Young High Pike are the addresses of the two potential sites in Vestal. Each site lies within a 5 minute walking distance from the Vestal town center and the public bus line to Knoxville.

Primarily three building types are seen in the area of Vestal with variances in scale, material palette, and layout. These three building types use materials and techniques that relate to the landscape, climate, and tradition of east Tennessee. These building types are typically single family residences and employ a material palette that uses both local and imported materials. The most common materials used are stone and wood with some metal and vinyl used for roofing and siding. These materials are seen throughout residential parts of Knoxville and east Tennessee as well. This sections shows the basic construction techniques use skills and construction knowledge of local craftsmen and builders. Wooden framing, pitched roof and vinyl, brick or stone siding are all typical of the architecture of Vestal.

Wood Framed Construction

Masonary + Composite

Knoxville and the surrounding area is populated with trees that can provide a substantial amount of wood. There is a saw mill (for processing trees into lumber for construction) right outside of the Knoxville region. Wood is used throughout Knoxville, primarily for residential projects. Is is easily accessible and relatively cheap to build with. Most of the housing in Knoxville is constructed using wood because of its reasonable cost and its reliability in strength. For the community of Vestal, using wood as a construction material

28|

Phase 1

could be a cost efficient method to use, simply because it is one of the quicker and easier forms of construction found within the surrounding area. However, other materials could potentially be more efficient and would need to be considered. Using wood has its advantages, but it typically requires more skill to build with. In order to use wood in a residential house, particularly in the structure, it takes a trained person. The residents of Vestal could potentially learn to construct with wood, if someone was helping guide them.

Masonry and concrete are easily accessible to the region surrounding Knoxville. There are a few concrete plants within a 20 mile radius of Vestal and there is a large masonry (brick/block) factory outside of the city that produces an abundant amount of bricks. Concrete is primarily used in larger construction projects, such as commercial (office) buildings. Concrete is intended to be implemented for structural uses more so than for looks. Brick is mostly used in residential homes as cladding (for looks/aesthetics) rather than for structure. Using bricks as structure is possible, but it is more expensive and complicated. Therefore, the construction technique of using brick for structure was fazed out many years ago.

For the people of Vestal, some may have a job that has provided them with the skills necessary to use these materials in a residential setting, but it is unlikely. For instance, concrete typically requires very little skill if it is going to be used for something basic. However if it is going to be used for structural purposes, it will take someone who has more experience to handle the material. While there are proper ways to lay brick that require a skilled hand, a local resident could be taught how to use the material. This would allow them to help aid in the construction of a low-tech, low budget project that incorporates masonry and concrete, whether it was their own house or a community project.

Expansion and Phasing: Holding House “With a common desire to remain on the street despite the urgent need to repair their homes, residents were hesitant to move forward with any plans that would displace them, even temporarily. The challenge was how to redevelop without relying upon relocation or incurring steep financial burden. bcWORKSHOP and the residents began by exploring alternative solutions. Through neighborhood meetings, the idea emerged to build a new residence on the street that would serve as a temporary home for each family during the evaluation and renovation/ rebuilding of their homes. The Holding House model delivered a new value to this community by rebuilding it while retaining its social cohesion.” -buildingcommunityWORKSHOP

Construction: De-constructing and re-constructing 5 family homes “Next, one by one, each family moved into the Holding House and was closely involved in the design and construction of the rebuilding of their homes. As the original structures measured 625 square feet each, larger contemporary homes would have been inappropriate for the scale of the street. Thoughtful design driven by resident input resulted in functional, energy efficient homes with small footprints. The largest rebuilt home measures just 975 square feet distributed on two stories, accommodating a large, multigenerational household.” -buildingcommunityWORKSHOP

Life-Cycle: “Instead of conventional demolition, each existing home was carefully deconstructed to preserve the materials. The incorporation of those reclaimed materials in the new home preserve the memory of the old home and the familial connections to each place... Construction: The new Green street design features a system that maximizes the filtration of rainfall and other runoff. The street width for traffic is reduced, limiting the use of impervious concrete and improving pedestrian safety. All aspects if the initiative were optimized for multiple dimensions of performance... The addition of solar power and solar thermal systems to the homes and educating the residents on the systems assist in reducing their energy consumption and utility costs.” -buildingcommunityWORKSHOP

Demographic: “Many Congo Street residents are the children and grandchildren of former renters and witness to multiple generations of its tight-knit community. The area continues to struggle with poverty, language barriers, low educational attainment, lack of job skills and vocational opportunities, and other challenges of lower-income communities...

Precedent Analysis: Quinta Monroy in Iquique, Chile Elemental

Existing Infrastructure: The city of Iquique, Chile has a population of around 200,000 and the urban fabric is highly dense. The site, which is 5,000 square meters, is located roughly in the center of the city, near the downtown area. The location allows residents to have access to the city’s opportunities.

Context 58|

Phase 1

Climate: Iquique lies just west of the Atacama Desert, along the Pacific coast. The climate conditions are mild desert-like with an average high of 71.7°F and an average low of 61.5°F. There is hardly any rainfall throughout the year.

Social: The entire site consists of 93 low-income households. The units are arranged so that they form four clusters, each with their own courtyard area. The courtyards are intended to be public community spaces that are shared by the approximately 20 families who live in the surrounding units. Each courtyard has restricted access to those living in the cluster.

Community Precedent Analysis: Quinta Monroy in Iquique, Chile

|59


Expansion: Within the voids between each unit, there is enough space for the residents of both the upper and lower levels to expand (double) their living spaces. The lower picture illustrates this expansion.

Construction: The construction used reinforced concrete framing and concrete blocks as the infill to the main structure. The secondary structure is wooden framing and panels, so residents may easily expand without harming the home’s structural integrity.

Phasing: There were two phases to the project. The first phase included building half of the building. This served as the base structure. The second phase is an ongoing process. It occurs when the residents have enough money and the ability to expand on their own.

Adaptability 60|

Phase 1

COST: The budget was $7,500 (US currency) per unit. This included everything involved in the first phase of the building (the land, the infrastructure, etc.).

Materials Precedent Analysis: Quinta Monroy in Iquique, Chile

|61


SKILLS: The building was designed so that when the residents had the capability to expand, it would require little skill to increase their living space. PASSIVE SYSTEMS: The passive system found within this project is natual ventilation through both the doors and windows. These openings provide cross ventilation within the home.

Materials 62|

Phase 1

DEMOGRAPHICS: The amount of people living in each unit is determined by the residents themselves. The size of their unit will help determine that amount. As a whole, their income average is very low. Prior to construction, the area had developed into a community that had a low quality of living. BUILDING PROGRAM: Each one of the units was initially built to be approximately 350 square feet. When fully expanded, the units have the potential to be 750 square feet.The base design included structure, access stairs, doorways and plumbing. The rest of the programming was left up to the residents.

Analysis:

To help revitalize Vestal through the development of an affordable, sustainable housing community.

The site presents the initial challenge of how to fit ten to twelve housing units on only .8 of an acre. The site also has steep topography, which slopes down to a creek that runs through the middle of the site. This results in even less area to work with. Another initial concern is how to incorporate outdoor community space within the site that everyone will be able to use. Our response to the steep topography is to create a stepping terrace on the northern side of the site. This terrace will help to organize both the individual lots and the community space. The common house and the parking will be located to the south of the creek. The common house will sit on grade, while the parking will be located on a built platform. In order to provide equal amounts of space to each of the families, there will

need to be six lots, each with two houses, on the northern part of the site. Each lot (30’ x 45’) will be divided into six (15’ x 15’) blocks. The family will build on two of these blocks, while the last block will serve as their private outdoor space. Housing design patterns are developed to help guide the arrangement of the housing prototypes. Each house begins as a 15’ x 30’ space with the potential to later expand vertically. Expansion will allow for additional bedrooms and/or a home office to be added, as the family sees fit. For the construction system, we propose using pole barn construction, with Hempcrete as the insulation material. These materials and construction methods should allow for the house to easily expand vertically in the future.

Abstract: The project focuses on providing affordable housing for low-income families, specifically in the Vestal community of South Knoxville. The chosen site has unique conditions, which include steep topography and a creek running through the middle of the site. The vision for the project is to develop a sense of community throughout. This is accomplished on the site level through the use of a common house, as well as a large community garden running through the central corridor. Parking also contributes by being placed away from the houses and therefore encouraging residents to interact as they walk home. Within the site we have designated five lots, with each lot

Phase 3

containing two houses. On the lot level, community is explored through the use of a shared front porch. As for the actual houses, six different prototypes were developed. Each house starts off as a one-bedroom 450 sq. ft. home, with the potential for later (vertical) expansion. Each house has an open floor plan that encourages community within the family. Due to affordability and expandability, construction was very important in this project. We chose to use a pole barn system that would allow for vertical expansion to easily take place. We explored using Hempcrete as our insulation. This allowed for the construction system to become innovative.

Pedestrian Circulation

This site is currently an overgrown mess. There are very few living trees worth saving on the site. Most of the greenery is composed of weeds and wild shrubs. This thick growth has created a place where people dump trash, and perform other illegal activities. We wanted to clean up to space and provide clear site lines to establish a sense of safety for whoever lives on the site.

nated. For these reasons, we decided to have a large portion of our site become a community farm, and another large portion become a semi-private garden way.

A large amount over water runoff passes through the site on its way to the creek southwest of our site. This made a large garden/ farm on our site more fathomable. As the water runs through the site, the plants are watered and the need for expensive irrigation systems is elimi-

The houses line the southwest side of the site and are separate from one another. This separation, along with southward orientation opens up many possibilities for passive heating and cooling. Most of the winds come from the south, so passive ventilation techniques can easily be used. The slight skewing of the house from true south actually provides more opportunity for passive heating before bedtime in the winter. The outdoor spaces, along with passive strategies, were our biggest drivers in planning the site.

Abstract:

Daylighting

Passive Heating

This project seeks to provide an affordable housing option for low-income individuals looking for ways to supplement their income; and to create a strong community presence in the fragmented suburban-rural townscape of Vestal, Tennessee. We explored the possibility of how food production could find its way into the suburban environment as a public amenity, an economic catalyst, and as a service to the community.

Because this development is intended to be affordable to individuals with low incomes, among our primary goals was to create efficient, passive, and low-cost housing. Our design of these housing units is based on passive heating and cooling strategies, as well as day-lighting strategies, in order to redefine the basic guidelines of an American archetype— the farmhouse.

Our site program includes ten singlefamily housing units that, together, take up less than half an acre of a four-acre development, while the remaining space is used for a highly productive communal micro-farm and farmer’s market.

Through this project we hope to encourage high-thought, low-tech design as well as demonstrate the social impact that architecture can have—not only at the scale of the building, but also at the scale of the site, community, and its greater context.

Vision:

Analysis:

To provide an integrated environment that establishes a positive direction for the redevelopment of the Vestal community through sustainable design.

To create an effective housing community, we designed a variety of housing sizes with a combination of row houses and detached single family homes to allow for a wide variety of options for expansion. These houese were designed with expansion in mind. As the family grew or ones budget increased, certain additions to the home could be purchased and added without disrupting the current resident. These expansions were designed to fit the existing module of each home. (4x8). The idea behind this growing home, is to promote variation in housing which would in tern promote ownership. The expansions work in a two step process. Within this process, smaller steps can be taken to stretch a budget, or allow the family to test a variety of space types before adding a permanet addition to their home. The major steps are a “soft expansion”, a space such as an

80|

Phase 2

outdoor room or covered patio. These spaces would not be thermally enclosed, or have a breathable skin that provides some protection from the elements. The second phase would be a “hard expansion”. This expansion type would involve making a direct connection the the interior of the home and enclosing the new space with a thermal envelope. These new rooms can become bedrooms, dining rooms, offices or any other needed extra space. We developed a one bedroom housing prototype with a few variations in footprint to allow for different kinds of expansions. In the prototype home, we have specified guidelines for percentage of floor space devoted to certain program. This in part was to more easily explain how spaces related to one another in a typical American home. This phase of the project was carried out in tandem wtih Darpan Aroroa of Vasad, India.

Adam Bates + Sarah Howell

|81


Analysis: BEDROOMS 40% of Total Space_Adjacency of bedrooms to other spaces of the home with consideration of noise and privacy is important. Also allow for adequate natural light. BATHROOMS 10% of Total Space_At least one bath or shower along with a toilet is needed. As a home would expand into a two or three bedroom home, generally there would need to be two full bathrooms for bathing privacy, but one bathroom should be available to be used by guests in the home. KITCHEN 20% of Total Space_The kitchen and dining space should be a very versatile and

flexible space in the home. Some families may choose to build a separate dining room adjacent to the kitchen once they are able to expand, but for the prototype home, these will all be one integrated space. Basic appliance needs would consist of a stove, sink and fridge for the kitchen. LIVING 25% of Total Space_Living space should flow into the adjacent kitchen and dining space. It should also be close to the main entrance to the home. As the main entertainment space, it should be one of the largest and be spacious enough for the entire family as well as guests.

Abstract: After the foundry, the project began to move into a slightly different direction. We learned from our presentation that our concept was solid and interesting, but the biggest concern of our critics was the feasability of the expansions. The next step was to take the idea and make it real. Using the same idea, as far as floor space percentages, I began to redraw the housing plans. Rather than having a wide range of beginning options, I started with the smallest cheapest space I could imagine. This resulted in a 315

84|

Phase 3

square foot home. After modifying the interior layout and eliminating hallways or small wated spaces, the base floor plan was set at 400 square feet and became “Model_1�. After reassing the plans, the home began to reflect it original modular design that had been intended. Each 12 foot section of the home became its own individual piece within the framework of the house. These pieces could potentially be arrange in any desired order, with minor adjustments to some interior walls. The arrangement I represent was just one path that could be taken with this design.

Adam Bates

Model_1 The first home in the progression is a 410 sqf 1 BR/Bath lofted home. The loft space, accessed by ladder, is a generous seven feet clear for 140 sqf then reduces to 6 feet for the remaining 55 sqf. The area can be divided in a number of ways. Featured, is a double bed with home office and two twin beds with ample storage.This housing model is designed for a single individual or a married couple.

Model_2 The second home in the series features a master bed and bath. This model, as well as any of the expanded homes can be purchased up front rather than upgrading. The size of this home enables the owners to open a private porch to the outdoors. This interpretation of the dogtrot brings many passive benefits to the home. Rather than simply adding another bedroom, a second lofted room can be added with a bonus room or sun room below.

Model_4

The patio on the rear of the home is a very flexible space once the slab has been expanded. The owners can choose to leave the slab exposed to have an open patio facing the public yard, or they can elect to cover the space and finish the exterior with screens or glass. Again, this space could become enclosed, but would benefit more from a full 12 foot slab expansion.

The final phase of this series, is a full 3 bedroom with two and a half baths. The home could expand more, but the farther enclosed spaces are from the breeze way, the less effective the passive benefits become. Additional indoor/outdoor spaces can exist, but lot size may become an issue. The owner can elect to continue extending the wrap around porch, or enclose the space and create a hallway between rooms.

Abstract: In this rural site, we wanted to create an integrated community that is tied together through orienting the homes toward a shared community space. Each house connects to a smaller shared outdoor entry space which is oriented to the central courtyard space. This shared space provides entry to each individual house while emphasizing each houses orientation to the central courtyard space. Three homes are connected rhough each shared space that connects directly to the larger central courtyard space. The rainwater collected from the three adjacent houses combine within this shared space, and water is directed into a cistern. The community orientation takes advantage of prevailing winds by opening up towards the southern ocean breeze. This allows wind to move through the site alleys and between buildings to cool and ventilate the interior courtyard.

98|

Phase 3

Through studies of pattern language, we focused on creating lots of outdoor space and different types of courtyards. Each home has a front porch condition adjacent to the shared space where people can spend time. There are separate main courtyard and service courtyard spaces. The roof terrace is an important element of any Indian home due to the hot climate. Main courtyard spaces always have multiple rooms connecting toward them, as well as opportunities for the walls of these rooms to open up further and create breezeways. Surrounding the central community space, an arcade acts as an aqueduct to carry rainwater to the cistern. The arcade has an integrated system of fabric above for shading this space to create a more pleasant space to spend time.

It should give importance to the practices of the culture. 03. Be flexible. Building should adapt to people, not people to building. 04. Is not iconic. 05. Incremental. Should provide a strategy to develop in affordable, responsible phases. Predictable expansion, allows expansion without encouraging sprawl. 06. Easily maintainable. Front-end investment prevents long-term problems. Use local materials. Passive systems.

Vaghnagar, India

During phase 2 of the project we focused on developing a master plan. The site is in Vaghnagar, India a small village on the west coast of India. The goal was to develop a master plan for the chosen area of the village presented to us by our Indian teammates that would take into account the design problems present in the village, but also be able to transform to address alternate contexts within India. In order to accomplish this we created a series of 3 videos that communicate our intentions and questions to our Indian counterparts in Ahmedabad. Because of the time difference and lack of resources to communicate directly, we found that this was the most effective way to present our design process to our teammates. At the end of phase 2, we presented at a public forum deemed the foundry. The site model illustrated the progression of the site plan from top to bottom. Each cluster shows a different level of resolution of the master plan.

Site Site Division_ The site is divided into lots ranging from 2000 sq. ft. to 2600 sq. ft. Each lot perimeter is claimed and marked before construction. This division throughout the entire site allows for public spaces to be claimed and not overwhelmed by the incremental building that is commonplace in India. Shared Courtyard_ Shared courtyards and public outdoor spaces already exist in the village. But creating three new courtyards the project is simply continuing the contextual tradition. Each courtyard is located within the center of the block and is connected to the interior streets. These courtyards define at least one edge of each housing lot. Interior Streets_ Interior streets are created to retain the existing connections within the village. These streets spilt the site, keeping the scale contextual, as well as providing a locater for the shared courtyards. Three streets are added to the site. Fifty Percent_ Within each lot, fifty percent of the given area will be built. This built percentage is made of a combination of enclosed and partially enclosed spaces. The remaining fifty percent of the lot is purposed for future expansion and private courtyards.

Clusters Organization_ A cluster organization, as opposed to a row house organization, allows the units to be situated around public space. Amenities_ The courtyard holds amenities for each cluster. A percolating well is placed in each courtyard for the use of the cluster grouping. Any future sewage options would be located within the courtyard as well. Extra work space or cattle space would have the option to expand into this shared courtyard. Access to Shared Courtyard_ Each shared courtyard is connected to each cluster housing. Every unit has one access point to the shared courtyard. The private courtyard in each lots acts as the transition space from the housing enclosure to the shared courtyard. Street Edge_ Every unit within the site is situated along the existing street. Every unit must hold the street edge. This can be done either through use of a property-defining wall or through the use of part of the house. One entrance should be on the street edge.

Housing Unit Courtyard House_ The initial organization of the programmatic elements was based on the concept of a courtyard house. The courtyard house allows the project to use the strategies from of: “Locating of Outdoor Rooms”, “Permeable Buildings”, and “Shady Courtyards”. Expansion_ Every housing unit is designed to have the ability to further expand. The piece of the house containing the bedrooms and bathrooms has the ability to add a secondary floor. This second floor would be connected by the addition of a staircase on the front stoop. Traditional Organization_ Typical Indian homes follow a set of organizational traditions. These traditions include: the patriarchal bedroom in the southwest, Puja in the north section of the house, and for the center of the house to remain open (Brahmasthan). Program_ Each housing units will be made up of the same set of program: Three bedrooms (100 sq. ft. each) Kitchen (150 sq. ft.) Living/Dining (350 sq. ft.) Bathroom (70 sq. ft.) Puja and Stoop

Rural Indian Housing Vaghnagar, India

Abstract: After the development of the master plan and cluster organization in Phase Two, the individual housing units were designed. Two different housing units are used in the master plan. Each unit follows the same principles as the other, only varying in organization and adjacencies. All courtyards within individual lots have access to the cluster courtyard as defined in the master planning stage in Phase One. Each unit is comprised of two programmatic pieces: living and social. These two pieces are organized around a central courtyard within each housing lot. This central courtyard is connected to the remaining open space with in the lot. Brick is the primary material used in the construction. Stone is also used for the foundation and plinth as well as concrete in very limited places. Vaulting and arching is used to create the spans within the houses. Each vault is part of the water collection system within the house. The rainwater that hits a vault is then funneled

into a small drain that feeds to a scupper. These scuppers flow into the central courtyard of each house. The slope of the courtyard allows the water to flow into an underground cistern. Because the masonry walls and vaulting is repeated in the proportion and dimension, the housing units can be easily expanded upon. All expansion would have to remain in the established lot, but each unit is able to become two stories in India height.

Construct Prosperity through integrated community for the other half.

As a team, our vision was to construct prosperity through integrated community for the other half and our intent was to preserve form and instill function. To achieve these goals, we researched traditional climatic strategies, family patterns, seismic design, construction methods, and life cycles to provide innovative solutions. We created a series of diagrams to express our ideas. Due to the hot climate, it was important to keep passive cooling strategies in mind. Materials used, and construction techniques are very important. Keeping future expansion in mind was a difficult task to overcome. We thought that building a good ground framework would best serve vertical expansion, which would maintain ground floor courtyard space.

Intention: Preserve form and instill function

ing buildings that would have to be demolished before constructing our new plan. For this reason and others, we saw the process of construction as being incremental. The construction of each plot would happen in phases as the new buildings were afforded. We envisioned that this project would be mostly undertaken by the residence themselves. Therefore the designs have to be easily constructible. To best blend into the site, we strove to develop schemes that reflected the context. The surrounding houses were built by the citizens of Waghnagar so this is a good basis of what is manageable.

As a team, we intentionally worked to create various systems of expansion. With a light weight construction for upper floors, it could be possible to expand vertically by jacking the roof up one story. Incremental growth is important to this project because of the multi-generational family structure. Houses can easily have eight to ten people minimum. As the family grows, the house should be able to easily be altered and expanded by the family.

Climactic Strategies Bundle for Design In the hot and humid climate of South Western India, there are several design strategies to consider for creating more comfortable buildings. Through the design of this project this series of identified strategies were considered. Images courtesy of Mark DeKay

Abstract: The goal of this project is to research and design innovative housing for rural India. Working closely with a studio of university students from Vasad, India, we had the opportunity to have an on-the-ground look at the design needs of rural India. This joint studio showed me that the cultural criteria is as important an local construction materials and methods. The construction methods chosen for this project use heavy masonry construction for the base and lower floors, while lightweight bamboo construction is used for upper floors. This basic structural strategy is helpful for seismic reasons. The schemes developed allow for expansion as a multi-generational family grows. Responsible strategies within the design system help conserve valuable rainwater

and allow for a variety of thermal zones. Natural and passive systems are needed for these projects that lack many modern conveniences.

By working with our colleagues in India, we developed an integrated site strategy. Courtyards were an important part to the development of the site. When two plots met, we used that as an opportunity to have a shared utility wall. Along the utility wall are water towers that are used to distribute collected rainwater. We divided the plots amongst the group for design. This was done intentionally to individually investigate different strategies and methods. Therefore the end result of the project would have many variations to demonstrate possibilities.

Vaults and arches are the main way we choose to make spans within the house. However, for the basement level, it is difficult to use CEBs. This is the one area that concrete construction is necessary. A well vented basement level is a great place for food storage. It also can function as a bedroom during different seasons. Rainwater is collected into an underground cistern during the monsoon season. The water is used throughout the year by being pumped slowly pumped daily into a water tower between to house plots. Rainwater is an important recourse in India because they do not have direct water lines into their houses. In a village like Waghnagar, water is often pumped out of a well. Using a well is not preferred, as they have been depleting their water table.

Through research and analysis of the existing conditions, we considered materials and methods carefully. We learned from our colleagues in India that reinforced concrete and wood construction is very expensive. We chose to use a compressed earth block (CEB) because of its strength, durability, and popularity. Unlike brick, CEBs do not need to be baked in a kiln, which requires costly energy and management. Through articulating vaults and arches, open spans create space. For higher floor level spans, bamboo constriction is used. Mangalore roof tiles are extremely common, and we found this to be one of the easiest and most cost effective solution.
