During the reign of Ottoman Empire various peoples, each belonging to dif-ferent ethnic, religious, linguistic origins lived together. In the nineteenthcentury as the empire shrank into the limited area of anatolia, the ram-nants of these groups kept their cultural colours as minorities alongside theTurkish Muslim communities. Their culture was reflected in their lifestyle as well as on houses they lived in, within the framework of a generalcross-culture.This paper is to illustrate the strong ties between culture and vernacularresidential architecture. Three case studies are to be discussed by usingvisual material.In the first study collection of Turkish houses chosen from three dif-ferent localities shows features common to them all derived from the lifestyle of then users. This is an organic Architecture. Each House is shaped totheir requirements determined by the factors as site topography, orien-tation, owners taste etc. Another feature they all share is the introvertplanning organization. Turkish houses set a good example to unity in diver-sity.In the second study houses of a Greek minority group in a Western Anatoliantown examplify a different case. In contrast to the previous case these hous-es have a 'Miesion' concept of design came into being long before Mies vander Rohe. Instead of following function they seem to rule it. They can easilybe categorized into a few typological groups, each showing similar featuresof planning and facade treatment. Facade elements such as doors, windows,balconies are all standadized in the fashion of mass-production although thehouses were by no means constructed by the use of such a method. The third study displays an entirerly different case in its nature. While thearchitectural style of the houses of the first two cases are consistent inthemselves as a reflection of communities with homogeneous cultures, thethird group of residences exhibit an inconsistent variety in their stylesagain reflecting the heterogeneity of their owners, despite the fact that allare in the same town and were built within a certain period of time. Theseare residences of Levantine families lived in Turkey during the late nine-teenth and early twentieth century.
