1978 Mercer Island Treehouse. A whole home, down to the studs renovation with second story addition over garage, adding 700 sq feet of living space. Prior home was 3 bedrooms, 2.5 baths, now 5 bedrooms 3.5 baths. The open stairwell, custom rails and custom lighting finish the new modern aesthetic. Large, spacious kitchen was designed for entertaining and family needs and now opens to dining and formal areas. Mother in Law was added on lower level. Complete redesign of space, removed interior walls, opened up main floor for lifestyle and desired livability. A dramatic difference from the prior dark, closed off home. This Mercer Island Treehouse showcases stunning views of green and now allows light to flow through the open spaces with fantastic livability and flow.
