Mercer Island Addition

A thoughtful second-story addition that respects the existing mid-century footprint. The result: a primary suite retreat and a re-planned main floor with dramatically better flow.

Every Archius home begins as a conversation. On this project, we worked hand-in-hand with the family, the site's constraints, and the region's most trusted contractors to shape a house that feels deeply personal — quietly modern, warm at the edges, and built to last.

Materials were chosen for their honesty and patina — oak, honed stone, blackened metal, and lime-washed plaster. Daylight was studied section by section. The plan was refined until every room earned its place.
