"Ankara town spatial structure was stable until the mid-19th century, however a changing process began at the end of the century due to external effects. New and different "Bosnak" district began to develop consisting of a house pattern surrounded by widely spaced vineyards houses and vernacular town border. Construction of "kagir" buildings and perpendicular roads were supported by "Nizamnames" (new regulations). The house promoted the use of horse-drawn carriages. At the end of 19th century, the region entered a market economy with the building of the railway in 1892. Different social structures appeared in the life-style of people when the function of capital city shifted to Ankara (13 October 1923) and the Republic was declared as a new administrative form (29 October 1923). The aim of this study is to examine changes in the socio-economic structure and its reflection on housing; to set up the relation between structure, building material, function and economy, and to analyze these factors in the case of the 19th century Ankara houses."
