2.4 Townscape Analysis in Urban Conservation 
Evaluation of three-dimensional effects throughout the analysis 
process is important while defining the urban historic quarter on 
conservation applications. Organic growth of urban space, 
should be considered with evidences from the past with cultural 
heritage on these applications. 
Designing three-dimensional components is required for 
creation of cities that can continue to live its own potential. 
On Townscape Analysis of Structural Condition (Figure 6), 
relations of each component's geometric form and relations 
between each component's structural conditions are identified. 
Building Proportions, and Building Height are also evaluated on 
three-dimensional urban model. 
On  Townscape Analysis of Visual Quality, Facade 
Characteristics on Zeyrek Urban Historic Quarter are being 
evaluated as three-dimensional model data. Visual relations in 
urban space have been considered with visual unity, 
appropriateness and contrast. Rhythm and proportion relations 
have been structured on voids of the facade (Figure 7). 
Townscape analysis of accessibility makes circulation 
parameters such as privacy and permeability levels, street 
pattern, building entrances and front façades be legible on 
three-dimensional urban model. The relations of ownership 
pattern that surround the uses of components are identified on 
this analysis 
Analysis of harmony with identity defines the characteristics of 
component in urban pattern and appropriateness with urban 
historic quarter. 
2.5 Proposal for Townscape in Zeyrek Urban Historic 
Quarter 
Proposal for townscape in Zeyrek Urban Historic Quarter is 
prepared on three-dimensional model as survey and analysis of 
townscape. Main headlines through the application decisions 
on developing proposals (Figure 8): 
e After the evaluation of structural condition, building 
forms are proposed as appropriate as the urban 
pattern. 
e After the evaluation of visual quality, infill 
applications have been constituted as in harmony with 
the traditional architectural characteristics. 
e After the evaluation of circulation and accessibility, 
active and effective open public spaces have been 
arranged. 
e Proposals for conservation applications and building 
uses on listed architecture are evaluated through the 
urban identity and local architectural characteristics.
