Cedar Plank Houses
Where They Were Built: Indigenous nations of the Pacific Northwest—from southeast Alaska to northern California—built cedar plank houses to withstand cold, wet winters. Among them were the Chinook, Haida, Tlingit, Kwakiutl and Coast Salish people.
What They’re Made Of: For the most part, builders crafted tall rectangular, sloped-roof structures from red cedar posts and planks, sometimes over shallow earth excavations. Some of these coastal communal structures measured up to 400 feet long and 30 feet wide—once the largest in North America.
Why It Worked: Durable and easily repaired, cedar plank houses could last for centuries, but for many Northwest Coast tribes, they were also designed to be dismantled seasonally. According to Christina Wallace, a scholar of Coast Salish architecture, communities would transport the planks via canoe to reuse them at their temporary summer homes while leaving the main post-and-beam frame standing for their return.
Cultural Context: Archaeological evidence suggests this style dates back at least 7,000 years. These houses served as multipurpose community centers: “a food-processing and storage plant… a workshop, recreation center, temple, theater, and fortress,” as anthropologist Wayne Suttles described them. They were places for living, crafting, ceremony and celebration.
