Northwest Coast plank houses and Plains tepees differed significantly in their design, construction, and purpose.

Plains Tepees
* Design: Tepees were conical, portable tents featuring a circular floor plan.12
* Construction: They were built using a framework of wooden poles covered with dressed buffalo skins (or occasionally other materials like canvas or bark).12
* Purpose: Designed for mobility, tepees were ideal for the nomadic lifestyle of Plains peoples, as they could be easily disassembled and transported.1

Northwest Coast Plank Houses
* Design: These structures were rectilinear in floor plan, typically featuring vertical plank walls and gabled or shed roofs.3
* Construction: They were generally constructed from cedar, utilizing large posts and beams. While some groups used permanent frameworks, others designed houses with detachable siding and roofing that could be transported by canoe.3
* Purpose: These were substantial, often large-scale dwellings designed for winter village life. They served as communal spaces for multiple house groups, hosting significant social and ceremonial events like the potlatch.3

While tepees were optimized for the needs of a mobile, hunting-based society, plank houses were permanent or semi-permanent structures built to accommodate larger groups and complex social hierarchies in the Northwest.13
