Common houses were simple one-room stone or [G 03 / adobe] buildings with grass thatched roofs. A small door was the only opening except for a hole in the roof through which smoke escaped. A group of these small houses was built together in a walled enclosure, and several of these compounds made up a village.
In the Lake Titicaca and the northern highland regions, houses were slightly different. Slabs of stone were sometimes used to make a [G 21 / corbelled] roof and windows were often made. This architecture was not used in the Cuzco district.
