In northern America, the type of housing the Algonquian population preferred took the form of wetus. These easy-to-construct homes were typically made by covering a wooden frame with layers of birchwood and woven mats. They came in several forms — domed, conical and rectangular — and were around eight to ten feet high. Wetus were temporary structures that could be quickly erected in village groups during the communal farming season and wherever easy meat was available during winter when game provided the main source of food. Elsewhere, different types of housing prevailed. These included longhouses, tepees, grass houses, brush-shelters, wattle-and-daub houses and chickees.
