Çatalhöyük was composed entirely of domestic buildings, with no obvious public buildings. While some of the larger ones have rather ornate murals, these rooms' purpose remains unclear.[6] The population of the eastern mound has been estimated at up to 10,000 people, but population likely varied over the community’s history. An average population of between 5,000 to 8,000 is a reasonable estimate. The inhabitants lived in mud-brick houses that were crammed together in an agglutinative manner. No footpaths or streets were used between the dwellings, which were clustered in a honeycomb-like maze. Most were accessed by holes in the ceiling, with doors reached by ladders and stairs. The rooftops were effectively streets. The ceiling openings also served as the only source of ventilation, allowing smoke from the houses' open hearths and ovens to escape. - Halil
