What is the Washington architectural style?

There isn't a widely recognized or defined architectural style specifically referred to as the Washington architectural style. While there are various architectural styles found in the state of Washington, they are not limited to just that region and cannot be collectively labelled under one specific name.

Washington features diverse architectural styles that reflect different periods, influences, and the state's cultural heritage. For example, Seattle, one of the most prominent cities in Washington, is known for its eclectic mix of architectural styles, including the renowned Pacific Northwest modernism, characterized by simple lines, natural materials, and large windows integrating with the lush surroundings.
