This thesis aims to understand the building materials and construction techniques utilized in the traditional houses of the villages in Karaburun Peninsula; Küçükbahçe and Kösedere in particular. With this aim, a preliminary study is carried out in 13 historical villages of the Peninsula in order to understand their traditional building reservoir, preservation state of traditional buildings and materials and construction techniques. The results of the preliminary study showed that materials and techniques utilized are quite similar with slight differences between east and west zones of the Peninsula. Two villages, Küçükbahçe and Kösedere, that best represent these differences are selected from two zones. The traditional building reservoir in these two villages is further analyzed to understand materials and techniques applied in foundations, walls, floors, roofs and architectural elements. As conclusion, it is understood that hybrid construction system is used in both villages. The exterior walls are stone masonry; the inner walls are timber frame without infill. Although the system is similar, there are slight differences in materials choices. The stone material used in two villages differs in shape, size and color related with the source of the materials. This is related with different geological characteristics of east and west zones of the peninsula. Another difference observed in Küçükbahçe is the common use of reed instead of timber laths in timber frame walls. Timber flooring system is similar in both villages. The original flat roof system has slight differences related with the availability of materials. Reed is used instead of timber elements in Küçükbahçe. The soil type is also different. The soil type, that is called “geren” used in Küçükbahçe has higher clay content. The materials and technique of architectural elements are similar in both villages.
