In our country, there is at least one TOKİ housing application in almost all provinces and district centers. In fact, more than one application has been carried out in some city centers. However, since a certain population size and housing demand is sought in district settlements, these practices have not been implemented in very small district centers. However, TOKI practices are encountered even in villages due to various reasons. There are undoubtedly very different and important effects of TOKİ residential applications on urbanization. As a matter of fact, these housing projects create important changes on the population and social structures of the cities. However, academic studies on this subject in our country are not many. However, a remarkable increase in studies has recently been observed. In this article, Turkey's seven geographical regions from the selected cities, their impact on the horizontal development of the city of TOKI application has been considered with the help of satellite images. These cities are Afyonkarahisar, Batman, Bingöl, Burdur, Edirne, Karabük and Nevşehir. In these cities, which are medium sized in terms of population, it has been determined that there are mostly important changes in the horizontal development of the cities after the construction of TOKİ residences. Undoubtedly, the dimensions of the changes have been directly proportional to the choice of location and the number of dwellings. In some of the cities studied, TOKİ residences had a gravitational effect on the horizontal development of the cities. In some cities, horizontal development has taken place in different directions, except for the area where TOKI subjects are established. In Batman, Edirne and Karabük, TOKI's partial attraction effect was seen, while Afyonkarahisar, Bingöl, Burdur and Nevşehir were stronger. Therefore, there were a number of factors, particularly location selection and topographic conditions.
