due to changing public requirements and different user groups needingdifferent residential location, designers are persuaded to concentrate onapproaches that will fulfill the preference of users and the requirements ofuser-needs. however, whether the designed locations and settlements canfulfill the diverse and changing requirements and expectations of users ornot, is always open to discussion. This subject is becoming important day by day in countries like Turkeywhere public change is rapid, and where household change is continuouswith families of different size, and of diverse cultural and socio-economicalstructure. For this purpose, obtaining data that will support the theoreticalstudy regarding the dynamic stucture and location of usage types for thefamily is important. ın this study, the aim is to form the parameters thatwill obtain data for the accommodations to be designed in the future, bydetermining the corresponding features of private residential sites whereusers are not happy with their houses, where the changes they make aimsto satisfy their expectations and requirements from the house unit.under this scope, an in situ observation and a survey with users wasmade. The observations were performed in two stages, where in the firststage, architectural projects of the sites and houses were obtained fromauthorities and house-unit usage areas, location sizes and spatial-functionalrelations were determined; in the second stage, a survey was made withrandomly selected users to interrogate the alterations they made in theirhouses in terms of the house unit plan. They were asked to state thenegative features of their houses they are not happy with, the ideal typeof accommodation they wanted to own or move to, the type of alterationsthey have made in their houses. The outcome is that, most of the users arenot happy with their original plan types and plan sizes; and almost all havemade alterations of different sizes and scales in their houses.
