House Plans for Washington

Western Washington and Oregon share a building climate defined by near constant rain rather than extreme heat or cold: steep roof pitches shed water fast instead of holding onto moss and moisture, generous overhangs and covered porches keep entries dry, and a lot of the best building lots in this region are wooded, narrow, or sit on a slope, which favors a compact footprint over a sprawling one.

This collection focuses on cabin and A-frame plans with steep gable roofs, covered porches and decks, and footprints sized for narrow or rural wooded lots, the kind of design language that has always suited the Pacific Northwest cabin in the woods building tradition. Several plans here include a loft, which is a practical way to add space without widening the footprint on a tight or sloped lot.

These plans are not engineered for site specific snow load, seismic requirements, or the moisture and drainage detailing a wet climate site often needs. Confirm those requirements with your local building department, and our editable CAD files make it straightforward for a local engineer to review the design against your specific site.
