About this home

Perched above the shores of Haro Strait on San Juan Island’s coveted west side, this extraordinary waterfront estate embodies a graceful dialogue between architecture and nature. Designed by acclaimed firm Bohlin Cywinski Jackson (BCJ), the residence is privately positioned across 6 acres and 4 tax parcels, with 400± feet of pristine shoreline. Nearly 6,500 sf of thoughtfully composed living space follows the contours of the land, using expansive walls of glass, soaring ceilings and warm natural materials to bring the surrounding beauty indoors. Sweeping views of Haro Strait, the Olympic Mountains, passing whales and unforgettable western sunsets become part of the home’s everyday rhythm. Created for both relaxed island living and memorable gatherings, the residence offers a chef’s kitchen, elegant great room, serene primary suite, inviting guest accommodations, wine cellar and flexible space for fitness, hobbies or creative pursuits. A detached garage and workshop includes a private studio apartment with a full kitchen—ideal for guests, extended stays or an inspiring workspace. A fully equipped greenhouse, fenced gardens and open grounds further connect the property to its remarkable natural setting. Private, timeless and deeply rooted in its surroundings, this architecturally significant estate offers an exceptional opportunity to experience the very best of San Juan Island’s west-side waterfront lifestyle.
