Zeyrek Urban Historic Quarter 
2. THE RESTORATION OF TOWNSCAPE 
BY USING COMPUTER AIDED DESIGN SYSTEMS 
Zeyrek is located in Historical Peninsula of Istanbul on northern 
coast of Golden Horn. In 1983 Zeyrek, as a quarter of Istanbul 
was included in the World Heritage List because of historical, 
aesthetical an architectural characteristics. Most important 
monument of the site is Mosque of Zeyrek that had been 
Monastery of Christ Pantokrator on Byzantium Period. Variety 
on cultural structure of the site is reflected to urban space. 
Zeyrek has traditional organic pattern that is constituted with 
authentic timber Turkish houses (Figure 2). 
2.1 Documentation of the Data about Townscape on CAD 
Urban design and conservation projects that involve survey and 
analysis by using-dimensional data have been used as main 
references (GÜLERSOY ZEREN, Nuran, TEZER, Azime, 
YiGITER, Reyhan; 2001.), (KARAMAN, Aykut; 1993). Other 
documentation technique is survey of urban historic quarter. 
2.2 Three-Dimensional Modeling of Townscape 
Computer aided three-dimensional model gives many facilities 
and opportunities to be used preserve townscape. This model 
represents observation on many view ports with various range 
of scales. Being the aim of this study this model constitutes the 
base of survey and application studies in urban conservation of 
Zeyrek. 
Three-dimensional modeling of existing townscape is achieved 
by AutoCAD 2000 (Figure 3). In the process of modeling, the 
data such as three-dimensional coordinates that is the location 
on “x,y,z” coordinates of topography, streets and buildings. 
Data on facade is formed within references that is mentioned in 
previous part (Documentation of the Data about Townscape on 
CAD). 
2.3 Survey of Zeyrek Urban Historic Quarter 
In the survey and townscape analysis of Zeyrek Urban Historic 
Quarter three-dimensional data can be legible. So each 
townscape parameters that are framed on conceptual evaluation 
of urban space are considered on this model. 
Within the survey of Zeyrek Urban Historic Quarter, three- 
dimensional anaysis of Building Uses, Building Condition, 
Building Construction Material, Ownership, Building 
Occupancy, Listed Buildings have been developed. In this paper 
Analysis of Building Uses and Listed Buildings are presented 
(Figure 4 and 5). 
On the computer aided urban model data of each building is 
constructed on “layer” properties on computer-aided design. 
Render application is used to create analysis and then output is 
converted to jpeg format to get the use on a image output.
