Houses are rich resources for understanding prehistoric social structure. However, conventional working methods often handle houses as stable entities that reflect the nature of households and other social units. Social groups may be inadvertently rendered static in the process. A biographical understanding, in which the on-going transformation of built space is part of different kinds of human collaboration, allows us to explore the dynamic qualities of past communities. I examine detailed life-histories of four contemporary houses at Çatalhöyük in Central Turkey, using the site's fine stratigraphy to interrogate how furnishings, elaborations and rhythms of burial varied through each building's use-life. These trace shifting practice and performance in relation to built space. Çatalhöyük buildings’ social roles changed dramatically over their lives. The spatial dynamics observed suggest that commensal groups were less stable and less bound to specific houses than in more conventional views of the site, and interacted in unpredictable ways with larger forms of social collaboration. Ultimately, this suggests a more dynamic approach to both houses and social units in the Near East and the archaeology of houses generally.
