ABSTRACT
THE IDEAL CITY? - As the title of my mas-
ter thesis implies, the main aim of my work is to find out if an ideal city concept exists and which city concept is going to be the most ideal for the development of future cities. Therefore, the main goal of my work is to develop city concepts based on an “Urban Planning Toolbox”, which is grounded on a research on European and American city typologies. The question in this context is which aspects (American, European or both) can be better implemented on a building plot. This research will show the main differences and similarities between American and European city typologies. Aspects like history, tradition, urbanization or demographic change, economy, city development, the relationship between population and the urban structure need to be taken into consideration. There will be an analysis about European and American cities and local specifics and how they can be explained. Strengths and weaknesses are analyzed and directly set against each other. Furthermore, I will analyze an American as well as a European city in more detail. This means that an Austrian city will be compared with a matching American city. To gain a perspective for the future of cities, the task of the analysis is to obtain an understanding of diverse structures of cities. Furthermore “Classic Districts” and “Mixed-
Use-Districts” will be analyzed in more detail. The study examines the patterns and relationships of different districts depicted in diagrams created from different maps and aerial imagery. The insights of the concluding assessment of both city typologies are then listed to get an overview of the previous work. On the basis of the analysis and the list of key categories it is possible to compare towns or city typologies and filter out what the advantages, chances and main differences of both typologies are. Having considered advantages and disadvantages, problems and chances, key criteria for city planning can be explored. Therefore, potentials, general city planning principles and important aspects for developing city life will be elaborated. The potentials will be collected and based on this, an “Urban Planning Tool” will be developed. This instrument will allow to evolve different urban scenarios. The scenarios can consider American or European city planning principles, or both. The urban planning scenarios will show different characteristics and forms depending on which potentials and aspects will be selected from the “Urban Planning Toolbox”. To sum up, the result of my master thesis will be a proposal for urban planning scenarios based on key principles of American and European city typologies. Furthermore, it will give insights on the future of cities and how the advantages of them can be realized in a new scenario. Abstract

GENERAL GOALS
The main goal of my work is to develop a concept of a new urban space by taking into consideration American and European city typologies. The question in this context is which aspects (American, European or both) can be better implemented in a new urban area. To develop a well-grounded master plan, theoretical principles like the theory of city planning and an analysis about American and European city typologies, will provide a helpful basis for the design proposal. The objective in this context is to gain a better understanding of different urban models. By comparing and analyzing American and European City typologies and cities in detail the main criteria will be as follows:

Prologue I General goals
In the first part I will show main differences. Aspects like history, tradition, urbanization or demographic change, economy, city development, the relationship between population and the urban structure need to be taken into consideration. Based on the theoretical research strengths and weaknesses are analyzed and directly set against each other. Having considered advantages and disadvantages, problems and chances key criteria for city planning can be explored. The insights of the concluding assessment of both city typologies are then listed to get an overview of the previous work. On the basis of the analysis and the list of key categories it is possible to compare towns or city typologies and filter out what the advantages, chances and main differences of both typologies are.

URBAN MORPHOLOGY
“Urban morphology is the study of the city as human habitat.”1 “Urban morphologists concur: they analyze a city’s evolution from its formative years to its subsequent transformations, identifying and dissecting its various components.”2
The purpose of the following graph is to demonstrate the five different structural levels and how they relate to each other.
“Morphological analysis is based on three fundamental components: form, resolution, and time.”3
REGION
“The study seeks to understand the spatial structure and character of a metropolitan area, city, town or village.”4 1.2.1.2
CITY
STRUCTURAL LEVEL5
Looking at a city and its environment different layers can be identified. The different levels of a city structure build upon one another are: ‣‣
DISTRICT
the city, embedded in the region
‣‣ the district as a component of a city ‣‣
a block as a unit within a district
‣‣
the plot as a basic component of a city

The study in this chapter focuses on key issues of “Mixed-Use Districts” such as block structure, land-use mix, open-space distribution and character.
The insights of the different research areas are then listed to get an overview of the previous work and will serve as a basis for the design proposal. Essential positive aspects, strengths and chances are the basis for the last chapter of my thesis. They can either be of American or European origin, or both, and the goal is to show how the advantages of them can be realized in new urban concepts. ‣‣

The final chapter of my thesis takes the key criteria that have proved to be important in the previous analysis into consideration. As mentioned above the planning principles are seen from of an American and European point of view. The main question in this context is which aspects (American, European or both) can be better implemented in different urban concepts.
Figure 6: Parcel
First an “Urban Planning Tool” based on the basic potentials is developed. Therefore, the future of cities plays an important role in selecting different potentials. A design plan which shows a proposal for a specific building structure will be the last part of this chapter. On the basis of the “Urban Planning Tool” the building structure will be implemented in different urban planning scenarios.

HISTORY OF URBAN FORMS IN EUROPE AND THE UNITED STATES
“Settlement form is the spatial arrangement of persons doing things, the resulting spatial flows of persons, goods, and information, and the physical features which modify space in some way significant to those actions, including enclosures, surfaces, channels, ambiences, and objects. Further, the description must include the cyclical and secular changes in those spatial distributions, the control of space, and the perception of it.”6 The contrast between the United States and Europe is mainly striking in urban matters. On the one hand, there are European cities which have changed over a long period of time and on the other hand, there is the massive surge and cycle of rapid growth of American cities.7

2.1.1
MEDIEVAL CITY (~ 8TH – 15TH CENTURY)
‣‣
The development of European cities began long before the growth of American cities. Due to social and economic conditions, the urban form of European cities was subject to constant change and characteristic urban and historical structures have molded European cities up to this day. Based on the first stage of existence, medieval cities can be divided in five main categories. Three of them are of organic growth.8 ‣‣ Towns of roman origin, about to take a new lease of life. In this context it should be pointed out that the gridiron structure of roman towns was no longer effective and unplanned organic growth of the medieval norm took place. 8
Burgs,
founded in the 9th century as military bases. These cities often attained commercial functions later. ‣‣
Organic growth towns,
mostly from village settlements. These villages made use of geographical advantages and grew from villages to towns. In general, it can be said that a medieval village became a town when it grew up to a local trading center. In Addition, the presence of specialist industry encouraged the promotion from village to town status.
cf. Morris 1979, pp. 66–83

The other category of medieval town is divided into two sub-types: ‣‣
Bastide towns,
founded in France, England and Wales. Key factors of all bastides were predetermined plan forms, gridiron systems of rectilinear plot subdivisions and the grant of a house plot within the town. ‣‣
Planted towns,
founded throughout Europe generally. To summarize the constituent elements of the five groups mentioned above are normally:9 ‣‣
The wall with its towers and gates
‣‣
Streets and related circulation spaces
‣‣
The market place, probably with commercial buildings and a market hall
‣‣
The church, usually standing in its own space
‣‣
And the great mass of general town buildings and related private garden spaces. Figure 8: New Haven in 1641

EUROPEAN SETTLEMENTS (15TH CENTURY)
Cities in the United states have been planned since the advent of European settlements. In 1501, the first city founded by Europeans in America was built. Transportation determined the location of settlements which can be divided in:10
‣‣
English settlements
Instead of systematic design, growth was the reason for the rise of the first towns on the Atlantic coast. Thus, far town planning came into view as early as 1638 with New Haven in Connecticut. The site was chosen based on:11 ‣‣
‣‣ The land being sparsely inhabited as a result of European epidemics that reduced the native population substantially. cf. Morris 1979, 254 ff. cf. Hopkins
‣‣
Spanish settlements
The Laws of the Indies, which can be seen as the first American planning code, served as a guideline for hundreds of Spanish settlements. “The essential elements were a central square within a grid and public institutions situated around the square.” 14 The impact of Spanish rectilinear planning could be spotted in cities like Santa Fe, Los Angeles and San Antoni.15
‣‣
Its natural harbor
‣‣ The red cliffs of West and East Rock overlooking a plain surrounded by wilderness
10 11
“Nine large squares were arranged in rows of three, with the central square serving as the town common or green.” 12 This so-called “Nine Square Plan” became a characteristic feature of many English settlements.13
French settlements 16
France entered the New World over 10 years later than Spain. St. Louis on the Mississippi was founded in 1762, which marks the end of French urban settlement. 12 13 14 15 16

RESIDENCE CITY (~16TH – 18TH CENTURY)
From the 16th through the 18th century the concept of city planning was increased, seeing cities as a complex system of interconnected components dealing with public utility and beautification. 17 The three main design components of residence cities are:18 ‣‣
The primary straight street,
which provided the access to buildings and had direct connections with regional routes. It can be said that the medieval street was functionally insufficient and aesthetically unconsidered; therefore, in the main form of main routes, the primary straight street is a renaissance innovation. ‣‣
The use of gridiron
either as the basis of residential districts which were added to existing urban areas 17 18
9
cf. City Planning cf. Morris 1979, p. 123
along with a primary street for the design of other new urban areas, or for the entire layout of new towns. ‣‣
Enclosed space
which served symbolic and aesthetic purposes for example as a space in front of an important building or as a setting for a statue. New capital cities in the late seventeenth and eighteenth century were influenced by European baroque plans. For example, the plan for Annapolis, Maryland, prepared by Francis Nicholson in 1694 was one of these strategies. With its two great circles, the imposing “Blooms-bur Square,” and the several radiating diagonal streets, the layout introduced a new concept of civic design to colonial America.19 The high point of such plans was the design of Pierre L’Enfants who was responsible for the new federal city of Washington in 1791. 19

INDUSTRIAL CITY (~ 19TH CENTURY)
In America, two cities served as a model for nineteenth-century planning. On the one hand there is Manhattan with the strategy to plat the entire island with a rectilinear set of north-south avenues and east-west streets, an on the other hand Philadelphia, with its grid that sets an example for many cities. These plans transformed every piece of ground into an instantaneously distinguishable peace of real estate. Because of this, the standard gridded town was planned to be open to all possible residents and investors, which is one reason why many cities are based on the same principle as New York and Philadelphia.20 The nineteenth century also gave birth to many factory towns which grew rapidly and therefore became centers of production and population. This massive growth led in the next step to enormous urbanization and the development of great cities. 20
11
cf. City Planning
“Cities grew both upward and outward in the second half of the nineteenth century.”21 Products of steel construction, the elevator, tall buildings, and thus central business districts with establishments like department stores, office buildings, or banks were formed. One feature that distinguishes European from American cities is the absence of skyscrapers and in Europe Central Business Districts did not grow as heavy as they did in New York and Chicago.22 Furthermore, expansion along main transit lines favored the development of new neighborhoods which ranged from tracts of small “workingmen’s cottages” and cheap row housing to elegantly landscaped “dormitory suburbs” for the upper crust. The most common form of development was the “streetcar suburbs”.23 “These were usually subdivisions laid out as extensions of the city grid.” 24 21 22 23 24

City Planning cf. Hohenberg, p. 37 cf. City Planning City Planning
Riverside, served as a very significant model for suburbs. The model was designed by Olmsted and it provided large lots, park space, a commercial core around a commuter rail station and curving streets.25 At the time of massive expansion of industrial capitalism, the making of the urban maps followed similar lines both in the United States and in Europe.
Figure 13: Manhattan 1920
Therefore, pollution and diseases in the central cities in Europe lead to a separation of workplace and residence, just like in the US-Cities. In view of this fact the old pattern, such as living above the shop, gave way to the more homogeneous blocks of flats, row houses or detached villas. Progress in transport, like omnibuses, rails, trams, the underground, buses, and motor cars, with falling cost and improving quality, was key to the process.26 Thus, there was also a separation of living and working but not to the extent as in American cities. Furthermore, urban design elements such as tenements, work - and villa settlements developed. Despite the areal division of living and working there was a close side by side and the special quality of European cities still preserved.

NEW TOWNS ( 20TH CENTURY)
There was a way of change in thinking at the turn of the 20th century. The industrialized cities of the 19th century had a lot of disadvantages especially for factory workers. Therefore, theorists began to develop urban planning models in America as well as in Europe. There are two modifications of urban development in European cities. On the one hand, there was the closed development with gridiron city plans and a high floor area ratio and population density. On the other hand, there was the spacious city with ideas of modernism, the fact that urban planning became more and more professionalized at this period and the concepts like the “Garden city movement�.
In North America, the Garden City movement was also popular. Furthermore, city planning in general is due to reform activities at the end of the 19th century. The Parks movement, campaigns for housing regulations, the City Beautiful movement, and the zoning of land which became the most powerful instrument for monitoring urban growth.27 In summary, European and American cities always differed from one another because of variances in historical development. European cities have developed long before the rise of the car industry, while most American cities grew after the development of cars. That is the main reason why cities in the United States were often laid out in grid pattern But what are other differences or similarities of today’s cities in Europe and America? What are the advantages and problems? I try to answer these questions in the following sections of my thesis. 27

CITY STRUCTURE MODELS
Every city is different and offers a range of functions like residential, industrial and service functions. A lot of different models and theories have been developed through history to explain how these functions are organized in relationship to one another. I would like to mention that not every city can definitely be assigned to one of the following models but they remain useful as a concept to explain urban form. 2.2.1
As you can see, the first and smallest zone is the central business district, with its retail and wholesale sectors, followed by the zone of transition, characterized by industry and poorer-quality housing, the zone of factory workers’ homes, the zone of better residential units, an area of good apartment blocks and private housing and the commuter zone, a suburban dormitory zone characterized by single family dwellings.30 The size of the rings can differ, but the structure always remains the same.
CONCENTRIC ZONE THEORY
This model was formed in 1923 by E.W. Burgess, Robert Park and Roderick McKenzie and it was the first to analyze the allocation of social groups within urban areas. 28 Based on the study of one city (Chicago) at one point in time, it offers a description of urban development. Burgess maintained that the city tends to grow outwards in annular fashion from Zone I to Zone V. 29

2.2.2
SECTOR THEORY
.
Because the concentric zone model is not appropriate to lots of cities the earliest constructive criticism of Burgess’s model emerged from an analysis of the internal residential structure of 142 American cities by Hoyt in 1939.31 Homer Hoyt, suggested that a city develops in sectors instead of rings along highways or railroads and other transportation arteries. The main factor is that the model grows outwards if radial space exists and is not constrained by natural barriers like water bodies. While commercial functions would stay in the CBD, manufacturing functions would increase in a wedge close to transportation routes. On the one hand, residential functions would develop in wedge-shaped patterns with a sector of low-income housing attached to manufacturing sectors. On the other hand, segments of middle- and high-income households were situated as far away as possible of these functions. In general, it can be predicted that more recent cities tend to follow the Burgess model and older cities tend to follow the Hoyt model. 32

2.2.3
THE MULTIPLE NUCLEI THEORY
In 1945, two geographers, Chauncy Harris and Edward Ullman, established a third model to explain city formation. Their aim was to develop a model which shows the complex nature of urban areas, especially those of larger size. According to the multiple nuclei theory, most large cities do not grow around a single CBD but are shaped by a number of distinct cores.33 Around each core, related services gather. “For example, a university core may attract well-educated residents, pizzerias, and bookstores, whereas an airport may attract hotels, low-income residences, and warehouses. Dissonant activities will avoid clustering in the same area, explaining why heavy industry and high-income housing rarely exist in the same neighborhood.”34
‣‣
Some activities are limited to particu- lar sites because they have highly specialized needs.
‣‣
Some activities tend to cluster in the same district because subsequently they can carry on their activities more efficiently.
‣‣
Certain related activities, by their very nature, reject each other.
‣‣
Certain activities, unable to generate enough income to pay the high rents of certain sites, may be relegated to more inaccessible locations like some specialty shops.
The location and growth of these multiple nuclei are determined by a number of controlling factors:35

2.2.4
URBAN-REALMS THEORY
The key element of this model is the advent of large independent urban areas. Each area is independent of the traditional downtown and central city. Five characteristics shape ban-Realms Model: 36
Vance’s
Ur-
‣‣
The terrain (topographical and water barriers)
‣‣
The overall size of the metropolis
‣‣
The amount of economic activity within each realm
‣‣
The internal accessibility of each realm in relation to its dominant economic core
“The Urban Realms Model constitutes the latest step in identifying and modelling the modern American urban structure. It shows that the outer cities are not "satellites" of the central city, but are in fact becoming cities themselves and shaping the metropolis.”38
An urban realm is likely to become self-sufficient if:37 ‣‣
“The size of the overall metropolis is large”
‣‣
“There is a large amount of decentralized economic activity in the region”
‣‣
“Topography barriers isolate the suburban region”
‣‣
“Good internal accessibility for daily commercial and business travel exists (especially to airport)”

In the following I will compare a European and an American city in more detail. These two cities are Vienna and San Francisco. In summary, it can be said that on the one hand Vienna has grown, like most European cities, in a quite concentric way. One reason is for sure the historical development of European cities. On the other hand, the second city, San Francisco complies with the Urban-Realms Theory.

WHY VIENNA AND SAN FRANCISCO?
An important question of my master thesis was which city I would compare with one another.

The first city, Vienna, could be determined relative quickly, seeing as it is the capital of Austria, but a counterpart to the Austrian city had to be found. During the research for an appropriate city it became apparent that some factors played an important role: ‣‣ It was important that I had already visited the town to get an idea of how the city looks like to be able to draw the best possible comparison.

Floor Area Ratio is a more balanced indicator for density than population or dwellings, because it is more abstract and generic. Density shouldn’t depend on the uses or zoning.40 4.1.1
WHAT IS THE “FLOOR AREA RATIO” – FAR?
“FAR expresses the relationship between the amount of useable floor area permitted in a building (or buildings) and the area of the lot on which the building stands. It is obtained by dividing the gross floor area of a building by the total area of the lot.”41

Healthy transit and walkable urbanism need Floor area ratio’s to be at least 1,5 to 3,0. In Europe cities have FARs that are apparently over 3,0. In America most of the commercial areas have very small developed FARs of about 0,3. 40 41

There are some characteristics of density which have the same importance as FAR. These are the performances that define the quality of density, which are for example the insertion in the grid or the orientation. 42 The following study examines the patterns and relationships of different “Classic Districts”, depicted in diagrams created from different maps and aerial imagery. Facts about each district complement these figures.

STREET PATTERN
„Street pattern determines the shape and size of street blocks and establish the pattern of transportation routes that allow people and cars to move around the area.“ 43 Street pattern are an important factor for the overall aesthetic feel of the community. Each block fells different and on the one hand a street pattern that uses dead ends creates a sense of security and privacy on the other hand a rectangular grid may create a feeling of openness. The following section presents the various individual characteristics of street pattern:44

4.2.2.1 GRIDIRON45 Gridiron street patterns are a simply layout of a sequence of streets at right angles, forming either rectangular blocks or squares. Grids characterize organization and power, which is either religious, political, or commercial.
Figure 49: gridiron
4.2.2.2 ORGANIC46 “Organic streets start and end, seemingly at random and they curve back and forth. Organic streets can come from disorganized, fast-paced development, as it is common in today’s slums or it can grow slowly over time like many of European cities.�47 Organic street patterns are planned very sensitively, one building or a parcel at a time. Apparently random lines follow political divisions, watercourses, contour lines or other features.48

4.2.2.3 LOOSE GRID49 Gridiron and organic systems form the basis for the loose grid. On the one hand streets curve, as with the organic and on the other hand there are four-way intersections as with the gridiron. Most European Cities started on a stringent gridiron pattern and evolved into a more organic plan during the middle ages. As a contrast to that, street patterns that started off more organic can become formalized to gridiron streets, as in the case of Lower Manhattan.
Figure 51: loose grid
To summarize the loose street patterns fill the range between gridiron and organic forms. 4.2.2.4 RADIAL GRID50 The radial grid is much rarer than the other types of grid patterns. It is stringently geometric, regardless of consisting topography. Streets radiate from landmarks like palaces, state buildings or churches. You can find this kind of street pattern in palatial estates of Europe and capitals, as in Washington. Figure 52: radial grid

CONCLUSION
The study has demonstrated several ways to characterize different districts through a variety of facets. An important finding is that there is no single best district typology because in practice there are a lot of factors which have to be taken into consideration when devising a strategy for urban areas. A sufficiently detailed analysis defines the aspects and which of them are the best for a new district. The aspects are, as mentioned above, for example the orientation to the primary street, the type of street pattern, the average block size and so on. All in all, this chapter served as an illustration to demonstrate which types of districts exist in Vienna and San Francisco. For better comparability and to condense the previous chapter, all results of the different districts have been summarized in the following chart:

The objective in the chapter below is to gain a better understanding of different mixed use block developments. My study focuses on key issues such as block structure, land-use mix, open-space distribution, and character. The insights of the different inquiries are then listed to get an overview of the previous work and will provide assistance for the design proposal. Essential positive aspects, strengths and chances are the basis for a further development proposal of the district and the goal is to show how the advantages of them can be shown in different urban planning scenarios.

MIXED USE DISTRICT
Mixed Use Districts are singular developments that bring together a broad range of activities, including commercial, residential, and high-quality outdoor recreation activities.51 In the following, 4 different mixed use districts will be analyzed. These districts have been selected as follows:
1
2 kilometers
2
‣‣ As a first step the most densely area in Vienna and San Francisco was identified. ‣‣
Next mixed use districts were determined within a 2 km limit. The selection criterion was an average FAR of 3,00.
‣‣
This criterion considered four different districts were selected.

BLOCK SIZE
Block dimensions range from approx. 5,15-by- 51,85 m to 221,45-by-158,45 m. While it is hard to say what a “typical� block dimension is, widths between 90 and 120 meters tend to be the most flexible. This dimension allows a pedestrian to walk one side of the block in roughly a minute and a half, which is reasonable for pedestrian activity, yet it is also wide enough for phased development to occur flexibly. An urban block should be able to accommodate early development of a single-storey use as well as more intensive uses.52 Therefore, the block size in the last part of my master thesis will be 120-by-90 m.

CIRCULATION
Just one mixed use district is next to a major arterial street that has four to six lanes of two-way traffic. Narrower streets traverse all districts: double two-way travel lanes on the busiest streets, two single travel lanes for local streets.

To sum up, there are a variety of design features which help, for example, to create greater use of sidewalks by pedestrians and furthermore to create streets that are more attractive to shoppers or other visitors. In conclusion, the following diagram shows a cross-section of a street with useful features, based on the above analysis. Figure 95: street features

LAND USE MIX
A livable city must have a strong mix of uses. It has to offer space for living, working, culture, sport or education. In order for that movement between all the different functions to be as short, fast, and comfortable as possible the different types of space have to be assembled compactly. The more variously land uses are connected with one another, the better a city will work. The result is an interplay between different land use classifications and as a result of this, a city has a high quality of life. Moreover, the more integrated and varied the land use is in a development, the more inviting it is as a walkable mixed-use environment.56 Therefore, the main aspects of the intense density are the mix of uses and the compactness.
56
A Land use plan characteristically categorizes all the diverse land uses in a city. Land use classification standards vary from place to place, as all places are different from each other. Even the land use plans from San Francisco and Vienna differ from one another. Therefore, it was important to create a unified map for greater comparability of land use classifications. The land-use classifications of the four contrasting study areas were laid down as follows: ‣‣

The final land use classification were defined as follows: Mixed Residential use: A single building or site which offers a variety of land use classifications including residential uses. Mixed use: A single building or site which offers a variety of land use classifications without residential uses. Civic use: This group includes a wide range of land uses like uses for culture, education, or institutional and recreational facilities. Office use: These areas are used by businesses, including management, information or professional services. Industrial uses: This category typically includes land uses for production, distribution and repair. Residential use: This group includes places for living.

Block I Mixed Use District
Within the context of the analysis it became clear that there are different types of urban land use patterns: ‣‣ Balanced Mixed Use (Retail/Office/Residential) ‣‣
Residential Driven Mixed Use
‣‣
Retail Driven Mixed Use
The balanced and residential-driven mixed use projects tend to have more constant activity through a longer portion of the day and night, with fewer “single purpose” traffic moments. It is important to know that retail driven mixed use results in intense traffic, making streets wider and walking areas narrower. Due to the fact that all districts are mixeduse districts, all study areas include different functions, but the precise mixture varies. This can be seen as further potential. Some projects emphasize residential function, whereas others are more clearly shopping or employment destinations.

5.1.5.1 LIVABILITY INDEX57 “The Livability index is used to identify the relationship between streets and their densities and gives a correlation between the total area of built environment and the total area of open spaces in a street zone. This index takes into consideration not only open space around the buildings but also considers the open space that is free form cars, for pedestrian use only. The ratio of this livable land area to total construction is referred to as the “livability index”.”58 The index as mentioned above, “refers to the proportion of walkable open spaces in the total built area and is also used to identify the relationship between streets and their densities. This index gives a correlation between the total area of built environment and the total area of open spaces. When the built environment has a higher livability index value, people have a sense of lower density.”59

5.1.5.2 OPEN SPACE NETWORK Based on the places I studied, open space is typically a combination of parks, green areas, sport, event space and parking space. The distinguishing factor was the amount and degree of smaller, more diverse open spaces that interconnected, as opposed to a single grand space.

6.1
FUTURE OF THE CITY
“By 2025 the world’s urban population will have grown from today’s figure of 3.5 billion to an estimated 4.5 billion, while the rural population is only likely to increase very slightly from 3.4 billion to 3.5 billion. The United Nations estimates that about 75 percent of the world’s inhabitants will be living in cities in 2050, as compared to today’s figure of 50 percent.”62 The number of people who will live in cities will present a challenge for the future of urban regions. Although I analyzed different cities, they share one aspect, in particular the matter of how quality of life is respected. This is important for the development of the populations in their local environment and a crucial aspect to the future of the growth of cities.63 In the following, I will partly refer to research work by Jahn Gehl. He has a deep understanding of how we use the public domain and offers us the tools we need to improve the design of public spaces and, as a consequence, the quality of our lives in cities.64 “To me, a sustainable city would be a very people-friendly city. It would be a city with good public spaces and a city that is rather compact. It would be a city that really invites people to walk and bicycle as much as possible. A good walking and cycling environment 62 63 64

with a good public realm is also a good environment for public transport, so there is an important connection here as well. Strengthening public transportation will be essential in the future, in order to become less dependent on private cars and also in order for the city to become more people-friendly.”65 public transport
In the quote above, Jan Gehl summarizes the main qualities which characterize a sustainable city. As a summary one may say that the main key elements of a city are: ‣‣
Mobility
‣‣
Open Space
‣‣
Land use pattern and building development
6.1.1
MOBILITY
Current urban mobility in Vienna and especially in San Francisco characterize by countless inefficiencies like air pollution, traffic congestion and noise. The utilization rate of a car is below 5 % because 95 % of their lifetime cars are parked and thus they consume very valuable urban space. Up to 70 % of urban areas not occupied by buildings are reserved for cars. The relation of mobility to urban space and resources in the modern city has failed in all aspects of sustainability.66 Therefore, it is important to find ways to en65 66
Jan Gehl: Making healthy cities - Danish Architecture Centre cf. Urban mobility reloaded:
courage more alternative types of transport. These forms could be public transport, walking and cycling as well as car- and bike-sharing. Fever cars means more space for walking, meeting other people, or playing. cycling
walking
Hence, cities should create space for walking and cycling, increase the public transport system and, as mentioned before, enable bike- and car-share systems. Strengthening such systems means existing cities will be more people-friendly, keep us healthy and will bring us all together. 67 6.1.2
OPEN SPACES
The main ambition of a city is creating possibilities for human contact.68 Therefore, it is important that cities create open spaces, which can be: ‣‣
Parks
‣‣
Event spaces
‣‣
Green spaces
‣‣
Open spaces with restricted access
‣‣
Pedestrian zones
‣‣
Green ways
‣‣
etc.
Good urban design makes sure that places are well connected to each other and that open spaces are easy to get to.69 67 68 69
cf. Urban mobility reloaded: cf. Jacobs 1970 cf. Yin, Farmer 2012, p. 142
6.1.3
LAND USE PATTERN AND BUILDING DEVELOPMENT
The main aspects for a sustainable building development are a compact design and a good land use mix. If a city is compact enough you can walk, bike or take the public transport, according to what your daily needs are.70 Designs with mixed-land use patterns can help to create areas that have diverse uses and are lively spaces. A mixed-use district that includes buildings with residential apartments, offices, and shops is likely to have people coming and going at different times throughout the day. People tend to be attracted to places that are well used by lots of other people. 71 Reduced distances between workplaces, housing or retail businesses, great housing density and pedestrian and bicycle-friendly environments encourage a compact development. 72

POTENTIALS
In the following, all potentials from the preceding analysis are listed: In the next chapter the key elements are summarized and illustrated in the “Urban Planning Tool”. This tool serves as a basis for the final part of my master thesis.
The result of my master thesis will be a proposal for urban planning scenarios based on key principles of American and European city typologies. First, I will create an “Urban Planning Tool” and based on this, different scenarios will be developed. The scenarios can consider American or European city planning principles, or both.

Based on the above-mentioned building types a concept for urban developments was designed. Before an urban planning tool can be implemented a flexible pattern for city growth needed to be found. The next question in this aspect is how different land use classifications can be combined in one building.
Pattern for Urban Developments I Plot

programmatic division
The advantage of a block building typology is used. Advantages are for example a high flexibility and a clear separation of public and private space.
This step is important to reach a good connection within a mixed-use network. Figure 128: pattern concept 5

The result is a flexible building type with different heights, widths and functions of buildings.

URBAN PLANNING TOOL
Based on the analysis of urban areas in Vienna and San Francisco and the expertise gathered from the research on the future of cities the “Urban Planning Tool” works as follows: Figure 136: Toolbox

Based on the analysis, different open spaces were selected:
Figure 142: square
grassy open spaces
squares help to define an entire urban community
Parks are regularly the largest public space. A park helps to create space for pedestrian movement.

In addition to various building patterns the facade of the building should be designed in a flexible way. Three methods were developed:
Figure 146: balcony
The methods can be used separately or in combination. The advantages of an adaptive facade system leads to a new flexibility, sustainable urban development, increased density and space saving.
