About this home

A rare Lake Washington waterfront offering on Mercer Island, this newly constructed home is built by MacPherson Construction & Design and resides on over 121 feet of sun-filled, no-bank shoreline along Lake Washington. Defined by exceptional natural light and sweeping, uninterrupted lake views, the home offers a seamless connection between indoor living and the water, delivering a rare experience of waterfront living. Thoughtfully designed for both entertaining and everyday living, it features vaulted wood ceilings, textured stone accents, a chef’s kitchen with butler’s pantry, a large wine room, and a stand-behind bar. A two-tier theater room, spacious bonus room, private office, four ensuite bedrooms, and a spa-inspired primary suite with an expansive walk-in closet elevate everyday comfort and livability. Heated covered outdoor living extends the seasons with a lake-view patio, spa, fire pit, seating area, and putting green, completing this exceptional waterfront retreat.
