Questioning the spatial boundaries in suburban residential sites in Ankara: the case of Koru neighborhood

Bilir, Zeliha Irmak
As in many other professional disciplines, ‘spatial boundaries’ has been one of the current critically important research topics in the field of urban design. With the fast increase in population, urban areas which have rapidly sprawled, have brought increasingly our attention towards the importance of spatial boundaries in cities. Especially residential site borders have recently become a basic research topic since they have started to become more and more dominant urban design elements in urban areas. 'Spatial boundaries' perform various important functions. However, in urban areas, it has become more and more ambiguous how far spatial borders (for example, as the borders of residential sites) successfully and effectively fulfill these functions. Being located at the intersection of public and private spheres, and functioning to restrict visual and physical permeability, they affect the quality of urban areas. The major assumptions of this thesis lie on the residential border’s inability to fulfill their functions and their negative impact on being visually and physically impermeable. The assumptions of this research are tested in a prominent middleclass suburb in Ankara, the capital city of Turkey, through the direct observation, documenting and mapping of spatial boundaries of the 52 residential sites in Koru Neighborhood. This research examines the height, material, and visual and physical vi permeabilities of residential site boundaries, and maps them through color codes in order to understand their effects on urban areas. The research findings reveal that the spatial boundaries partly fulfill the functions of safety and security, giving identity, providing privacy, dualism, determining psychosocial behavior, dividing and providing order functions, and features in this neighborhood. It studies the visual and physical permeability level of residential site borders under the urban design principles, and the research findings reveal that impermeable borders negatively affect character, continuity, ease of movement, and access to green areas actively and passively. To convert these negative effects to positive ones, and to benefit from advantages of permeable borders that are rarely utilized, this thesis suggests that the boundaries, which are impossible to vanish, should be low, visually permeable or semi-permeable, especially in highrise apartment building’s sites. It also proposes that the spatial borders should be physically permeable or semi-permeable for pedestrians, and be made of evergreen plant material. If this is not desired by users, this research suggests that, at least, evergreen plant material should be used as spatial boundaries to support public health by letting people access green passively.


University campus design in spatial, social and political considerations
Ilgaz, Berkay; Barlas, Mehmet Adnan; Urban Design in City and Regional Planning Department (2014)
The subject matter of this research is university campus design, and it is discussed in a wider framework of some of the general concerns of the field of urban design. In this study the concept ‘campus’ is not only taken as model of university settlement, but in a broader sense, any type of space on which higher education institutions are found. The problem is defined in both a universal scale of the general issues and practices developed in the post industrial cities, and the case of Turkish higher educati...
Assessment of spaciousness in buildings via computer simulations: case studies on classrooms
Özyıldıran, Güler; İmamoğlu, Vacit; Department of Architecture (2015)
The interaction between people and built environment has been examined in the field of architectural psychology since the 1960s. In this field, “spaciousness” has been one of the most significant concepts which have been frequently reported in the semantic differential scales, such as Spaciousness-Crampedness Scale (S-C-S) developed by İmamoğlu (1975) and used in several experimental studies via real rooms and scale models in 1970s and 1980s. However, there are still crucial architectural dimensions which h...
On the concept of "field" in architectural theory and practice
Kuzlu, Emre; Aközer, Emel; Department of Architecture (2004)
This study aims at explaining the significance of the أfieldؤ concept in contemporary architecture and urbanism, in reference to the technical definitions of the term in different disciplines. In this context, it investigates the concepts of أfieldؤ in physics, psychology, art theory and criticism. It highlights the reinterpretation of the أfieldؤ concept in physics by eminent Gestalt psychologists, and its consequences for architecture and urbanism. Starting from the definitions of the concept of أfieldؤ b...
Reconsidering architectural program within the framework of conjectures and refutations: the design studies journal
Özten, Ülkü; Özkar, Mine; Department of Architecture (2014)
The discussion of program in the field of history and theory of the Modern Movement in architecture enters a new period in the 1960s and 70s under the influence of the strong embodiment of science and technology in the field of design research. Beginning with this period, the idea of program arises both in a series of generations parallel to a specialized, sophisticated understanding of design and as an autonomous professional area of study. While the concept was being largely developed under the influence ...
Design thinking in urbanism: Learning from the designers
Çalışkan, Olgu (Springer Science and Business Media LLC, 2012-12-01)
Since the design methods movement of the 1960s, design studies have made significant progress in our understanding of design thinking in general. Nevertheless, urbanism's enduring lack of interest in the cognitive insights of design has caused the field to continue to rely on early procedural models, which have been invalidated by the emerging debates in design studies. The shortcomings of this theoretical condition are proven mainly by the disputable conceptualisations of analysis and design in spatial pla...
