Page "Ancient Pueblo Peoples" Paragraph 49

While much of the construction in these sites conforms to common Pueblo architectural forms, including Kivas, towers, and pit-houses, the space constrictions of these alcoves necessitated what seems to have been a far denser concentration of their populations.

Mug House, a typical cliff dwelling of the period, was home to around 100 people who shared 94 small rooms and eight kivas built right up against each other and sharing many of their walls ; builders in these areas maximized space in any way they could and no areas were considered off-limits to construction.
