Figure 7. Build-up Situation of Historic Peninsula in 1929 and 
2000. 
In Historic Peninsula the neighborhoods on the coastal side of 
the district preserves their historic pattern from 1929 till 2000. 
After 1939 the density of the build-up space expanded from 
north to south direction and after the year 1970 a distinctive 
increase observed in all neighborhoods. 
3.5. Physical Quality of Buildings 
In this analysis the physical quality of buildings are evaluated 
by using Multi Criteria. Decision (MCD) with respect to the 
criterion. of building construction coefficient value (building 
land area/building area*number of stories), number of stories 
and physical condition of buildings. MCD is determined by 
assigning subjective points to the criterion expressed above. 
Iterated values in the neighborhood of building construction 
coefficient and building number of stories are accepted as 
represented values of the neighborhood. In this concept 
weighted points are assigned to building construction 
coefficient value and number of stories criterions with respect to 
the values differentiate from the represented character in the 
neighborhood. 
The intensity of the physical quality of buildings is evaluated in 
neighborhood scale and the geographic relations of those similar 
or dissimilar values are expressed. These evaluations guide the 
planners and decision makers to set the priority of the 
neighborhoods to construct conservation and development 
plans. For every single building, the criterions listed above are 
evaluated to construct MCD and those obtained values are 
expressed in the scale of neighborhood. 
First of all for the physical case of the building criterion; 
historic buildings are assigned high to low points by means of 
their physical case. — Although the condition of an historic 
building is poor it is assigned points because of the potential of 
carrying historic value and chance of probability to improve 
with appropriate restoration intervention. For non-historic 
buildings only the ones having good conditions get points for 
that criterion. 
Second stage is the number of stories criterion. In this stage 
firstly the most repeated number of stories of historic buildings 
for neighborhoods are calculated and accepted as representing 
value of that neighborhood. Then for every single building 
criterion points are assigned with respect to the represented 
value of the neighborhood. Both for historic and non-historic 
buildings having lower or equal to represented value of number 
of stories get high and others get low points. 
Building construction coefficient give us a way to understand 
the construction pattern of the neighborhood so, third step of the 
evaluation is to find out the most repeated building construction 
coefficient for historic buildings and it is accepted as 
represented building construction coefficient for neighborhood. 
And higher points are assigned to the buildings having same or 
918 
less regarding to the represented building construction 
coefficient value and the others get lower points for both 
historic and non-historic buildings.

Figure 8. Physical Quality of Buildings 
The following stage is to get the average of the assigned points 
for those four categories for all buildings and total building 
physical quality points are obtained in a subjective manner by 
using MCD. 
In the resulting map, places nearby Istiklal Street and northern 
parts of Beyoglu district have higher points by means of 
physical quality. For Historic Peninsula, a more complex 
situation is observed, coastal areas of that district, central 
business districts (CBD) of Fatih and Eminónü have relatively 
higher points. 
3.6. Resulting Analysis 
All the results of the analyses explained above are overlaid and 
a resulting map is obtained. In this analysis again a MCD is 
applied by using the percentage of historic buildings, ratio 
between historic buildings floor area and total area, ratio 
between historic and non-historic building floor areas; ratio 
between historic and non-historic building construction areas; 
change in the build-up space and physical quality of buildings 
analyses. In this concept weight points are assigned to the 
results of analyses listed above and a resulting map representing 
the general trend is obtained. 
Depending on the results of this analysis it is possible to 
conclude which neighborhood has historic value; how much 
affected from the structural change in time interval and beyond 
those entire criterion in which case the buildings’ conditions 
are. 
In a historic urban pattern expressing more than one criterion 
like percentage of historic buildings, density and expansion of 
historic buildings construction area, percentage of the change in 
time and buildings physical case; would assist us to determine 
planning and design stages and to understand the typical 
characteristics of the pattern to develop appropriate planning 
studies. Together with all those, geographic distribution of 
similar and dissimilar neighborhoods are clarified in terms of 
planning concepts in the resulting map 
In order to perform this analysis using MCD; the analyses listed 
above are used to assign appropriate points to the results of 
those analyses. In percentage of historic buildings analysis 
which shows the density of historic buildings; the higher valued
