In Turkey as elsewhere, building apartments at great scale to accommodate populations who come to settle in big cities has created many disappointments. On the other hand, studies on traditional architecture indicate possible relationships between the space organisation and the well being of the occupants. Therefore, we have investigated a sample of house plans originating from different regions of Turkey using space syntax, an analytical tool for studying spatial patterns. Our results show that in spite of apparent similarities structural differences embodied in the spatial structure of houses can be revealed.
