In Turkey while the production of urban space is based on individual plots in the nner areas of the city, urban peripheral areas face development based on the cale of urban block or neighbourhood. Although such a development pattern carries potentials to produce qualified urban forms, it is mainly characterized with its fragmented structure and lack of public spaces. Thus, aim of the thesis is to explain the deficiencies and potentials of design control practice in Turkey, specifically in peripheral areas. Evaluating the contemporary approaches in design control, the thesis provides a theoretical framework that elaborates the procedural and substantive dimensions of design control. It is proposed that the interrelation between the dimensions of design control cannot be conceived without considering the ways of control on private property. Therefore, the peculiar characteristics of Turkish design control -which is mainly derived from property relations- is evaluated within the framework provided in the theoretical part through a procedural and morphological analysis of &Ccedil / ayyolu area. It is argued that design control in Turkey, focusing on quantitative dimensions of urban form, disregards qualitative aspects that necessitate the consideration of elements of urban form and their morphological characteristics. Finally, it is claimed that urban design problem in Turkey cannot be reduced simply to the domination of private interests in planning process but it is actually a matter of planning understanding which suffers from its poor insight on the idea of design. In this respect, a reconstruction of planning mechanism around the focus of &ldquo / design control&rdquo / is a necessity for an effective public control on private property.

Public spaces play essential roles in urban life for the city, the public and individuals, by setting strong relations between urban space and social and cultural values. Public spaces and their essential components have multi-dimensional impacts on people. Public art, as a constituent of public space, includes a wide range of artworks, activities and outcomes, contributing to the significance of the places in a variety of ways. However, each culture, country and city, has diverse policies and outcomes of public art based on different perspectives. Focusing on the public art policies in Ankara over the last two decades, this thesis seeks to examine how far the recent policies have contributed to the city. By carrying out in-depth investigation on the public art work interventions and policies of the Ankara Metropolitan Municipality, the thesis assesses the multi-dimensional contributions of these policies and interventions. It seeks to discuss how far the public artwork policies of localities are crucial for creating genuine public spaces of cities.

Over 80-percent of the U.S. population lives in urban areas that occupy a mere 3-percent of the country's total area. Development problems and infrastructural stress caused by urban overpopulation can already be seen in the nation's largest cities. Scattered across North America are small towns that, at one time, were largely sustained by agriculture or industry, but have watched as farming and manufacturing operations leave them behind. Rooted in these economic conditions is the growing gap between metropolitan and nonmetropolitan areas. The high concentration of rural lands and high poverty rates in the South makes this region particularly vulnerable to the effects of rural economic distress, and put it in desperate need of solutions. For many small towns in Georgia, the last two decades have brought either rapid population growth, as seen in the areas surrounding Atlanta, or great population decline, most clearly depicted in the southeastern region of the state. Each condition produces a host of different challenges for these small communities, illustrating no simple solutions. It is the focus of this research to determine what proximities, economic assets, and formal characteristics are necessary for small towns in Georgia to successfully revitalize and grow. Furthermore, it is the aim of this research to present a means of analyzing the assets of small towns in order to determine where outside investment is most likely to make a difference, and how resources can best be utilized.

Urban air pollution is responsible for high levels of morbidity and mortality in exposed populations due to its effects on cardiovascular and respiratory function. Transportation-related air pollutants account for the majority of harmful air pollution in urban areas. Forests are known to reduce air pollution through their ability to facilitate dry deposition and atmospheric gas exchange. This work characterizes the interactions between transportation air pollutants and urban forests in Hillsborough County, Florida. A highly spatially resolved passive air sampling campaign was conducted to characterize local concentrations of nitrogen oxides, benzene, toluene, ethylbenzene, and xylenes (BTEX) in Hillsborough County, Florida. Sampling locations included a proportion of densely forested urban areas in order to determine the effects of Hillsborough County's urban forest resources on localized concentrations of selected transportation pollutants. Recommended approaches for the use of urban forests as an effective air pollution mitigation technique in Hillsborough County were generated based on results from the sampling campaign. Results show mean concentrations of 2.1 parts per billion and 6.5 µg/m3 for nitrogen oxides and total BTEX, respectively. High spatial variability in pollutant concentrations across Hillsborough County was observed, with the coefficient of variation found to be 0.61 for nitrogen oxides and 0.79 for total BTEX. Higher concentrations were observed along interstate highways, in urban areas of the county, and near select point sources in rural areas. Differences in concentrations within forested areas were observed, but were not statistically significant at the 95%#37; confidence level. These results can be used to identify elements of urban design which contribute to differences in concentrations and exposures. This information can be used to create more sustainable urban designs which promote health and equity of the population.

Berlin is one of the most dense cities for tenantable living, from nineteen century to the reunification decade in the late twentieth, the housing living cost always maintain an affordable level for multiple classes requirements. However, after step into twenty-one century, the urban gentrification sweeps out many affordable rental housing financed by city government, instead of higher cost for housing living in downtown Berlin. What I look for in this master design project is trying to broad a new view in how to develop the modern, affordable housing for diverse groups living in the inner city. / text

This study seeks to determine whether the process of mortgage finance liberalization, manifested in concurrent activities of securitization, deregulation, and neo-liberal policy, have resulted in changes to the tenure of residents in neighborhoods in Tampa Bay. It makes use of existing literature on gentrification and mortgage finance and compares those findings with three sample neighborhoods in and around the city of Tampa. To do so the thesis employs data collected from lenders pursuant to the Home Mortgage Disclosure Act, court records of sales and mortgages filed with the Clerk of the Circuit Court of Hillsborough County, and interviews with stakeholders such as community leaders, activists, residents and those involved in the lending industry. It was discovered that the sample neighborhoods largely conform to expectations about the general pattern of investment of mortgage dollars in core, peripheral, and semi-peripheral neighborhoods. Close analysis indicates that the liberalization of the mortgage process clearly increased the frequency of resident turnover, thus reducing the tenure of residents in each neighborhood to varying degrees. Neighborhoods where traditional, deposit oriented, banks and thrifts dominated the lending market saw a lower tendency for the rapid churning of housing and thus can be expected to possess a lower turnover in residents, fewer examples of foreclosure, and a greater level of wealth accumulation for the homeowner.

The ideal city project was a performance that presented the design for an ideal city with stories about how that imaginary city failed. The design was represented as a 4’0” x 4’0” wood and Styrofoam sculpture. Upon seeing this design, seven writers created scenes and monologues outlining the destruction of the city. The flaws they discovered were not designed into the city intentionally. In fact, the writers pointed to several different sources for the downfall ranging from issues with its layout to socio-political breakdowns. At the end of the performance the audience was left with the ruins of something that was once so full of hope. This piece was intended to serve as a reminder that cities are not predetermined utopias, but continually changing and evolving environments created by those who live in them. Even the best examples eventually fail or evolve into something different. However, this does not mean we stop trying to create better places to live. George Bernard Shaw said “A reasonable man adapts himself to his environment. An unreasonable man persists in attempting to adapt his environment to suit himself. Therefore, all progress depends on the unreasonable man.” Theater performances provide an excellent way to explore ideas and create dialogue about what these better places look like and how they function. / text

This thesis notes that there is a lack of systematic research investigating segregation patterns based on how public space is used and frequented by citizens. In order for understanding of urban segregation to reach beyond residential segregation, the extent to which public space facilitates co-presence between social groups is a key issue. The main concern in this thesis is to arrive at a deeper understanding of the critical role urban form plays in terms of co-presence in public space and in extension for social segregation. The argument builds on knowledge from other fields, arguing that co-presence is of utmost importance for societal processes: by sharing space and being co-present with others, which does not necessarily imply focused interaction, we gain information and knowledge from our fellow citizens and participate in processes that negotiate social structures, acceptable behaviours and identities. The sharing of space thus becomes a central part of ‘being in society’. It is furthermore through public space that material urban resources are accessible, an access that is dependent on both the location of the amenities in space but also the distribution of space, as structured and shaped by urban form, which creates the actual experience of access through space. Segregation is primarily defined as a social problem. However, in this thesis, it is made clear that it is also a spatial problem. While also broadening the conceptualisation of segregation, the main focus has been upon the role of the built environment. The socio-spatial link builds on social theories. However, these theories are weak when it comes to explaining where co-presence occurs. Addressing the spatial side of the problem, the thesis primarily builds on the architectural theory of space syntax that exactly aims to study the space-society relationship from the viewpoint of space and provides empirical evidence for the correspondence between urban form – as it is shaped by urban design and architecture – and the creation of co-presence as well as variations in its intensity and its constitution. In addition, key questions such as what people may have access to ‘just around the corner’ in terms of human resources or other urban amenities are elaborated. The distinct variations found between neighbourhoods are argued both to enrich the discussion on social exclusion and unequal living conditions and inform future urban planning and design. The thesis demonstrates that specific configurational properties have great impact on the pattern of co-presence. More specifically, it is found that a segregation of public space, a limited spatial reach and an uneven distribution of spatial centrality appears not to favour an exchange between neighbourhoods or access to urban resources across the city – findings that are highly critical for the urban segregation issue. Detailed configurational analysis of Stockholm reveals the performative aspects of different urban layouts related not only to local circumstances and character but, more importantly, to the further context of such layouts. Increased knowledge of how spatial configuration relates to social practices offers new insight into how different neighbourhoods and urban layouts perform socially and increases understanding of the social implications of spatial configuration. The findings of this study are argued to open up theoretical developments that address the social and political dimension of urban design with greater precision. Not least, this knowledge can influence public debate. The knowledge produced can furthermore be used in urban design practice and anti-segregation initiatives, identifying whether spatial interventions can make a contribution and if so, what physical interventions respond to the social ends in question, where the ultimate aim is an urban design that not only builds cities but societies too. / <p>QC 20131108</p>

Within the European Union, policies promoting integration and transnationalization have raised questions about the nature of borders and boundaries. With these shifts in conception emerge an opportunity to re-imagine how borders might be urbanized and developed. The Dreiländerecke (the Three Countries Corner between Switzerland, France, and Germany in Metrobasel) is one instance of this phenomenon, standing at the threshold of change towards increased transborder cooperation and a loosening of political boundaries. However, this process is hindered by residual urban barriers. This thesis investigates the liminal space of borders which provides a rich basis for forming a multi-scalar approach towards infrastructural, architectural, and programmatic strategies for cross-border development. Although connectivity is sought, it is not the ultimate aim, for unfettered integration risks a globalizing homogenization. Instead, this thesis investigates an architecture that facilitates the liminal process as core identities become translated at the meeting point of national cultures.

To respond to the global issue of sea level rise, this thesis examines architectural adaptation strategies by focusing on a low-lying coastal community in Dartmouth Cove in Halifax, Canada. Without a comprehensive adaptation strategy, these residents, along with 75% of the properties surrounding the harbour, will be forced to abandon their homes, resulting in a massive retreat from the coast. This project explores ways to build that can accommodate the future rise in sea level and population growth but are sensitive to the natural environment. It includes designs for urban organizations and amphibious housing blocks. The findings presented in this thesis suggest that amphibious architecture could become a viable solution for coastal environments in urban areas.
