Set along the coveted west side of San Juan Island, this extraordinary waterfront estate is a striking expression of contemporary architecture by the renowned firm Bohlin Cywinski Jackson. Privately positioned on 6 sunlit acres in 4 tax parcels with 400 feet of pristine shoreline, the residence offers nearly 6,500 square feet of thoughtfully designed living space where modern design meets the island's natural beauty. Dramatic volumes, floor-to-ceilings glass, and warm natural materials create an atmosphere of understated luxury while framing breathtaking views of Haro Strait and the Olympic Mountains. The main level is anchored by a chef's kitchen, sophisticated great room, and a serene primary suite designed for quiet retreat. The lower level offers inviting guest accommodations, a wine cellar, and flexible hobby or studio space. Completing the estate are a substantial workshop and garage, a fully equipped greenhouse, and fenced gardens — ideal for those seeking both beauty and self-sufficiency. Watch whales pass through Haro Strait, enjoy spectacular sunsets, and experience the rare privacy and tranquility that define San Juan Island's most sought-after west side living.
