The sloping Strata House, designed by COOP 15, exposes its layers on the Mercer Island site, extending the earth’s strata skyward. Water filtrates and opens entry of the house, defining an “escape” wing used for entertainment or a quiet retreat. A concrete base supports brick and wood siding, with a metal roof floating cloudlike above. Home to family of an industrial designer, the design's plan is open and glassy and has horizontal layers in its interior details.
