About this home

An exceptional offering on the coveted north side of Three Tree Point. This impeccably maintained waterfront estate features no-bank, level sandy beach frontage — a true rarity — with panoramic views of Puget Sound, the Olympics, marine life, and vibrant sunsets. Behind a private gated entry, low-maintenance grounds, an expansive deck, and seamless shoreline access set the stage. The custom-built residence offers soaring ceilings, rich hardwood floors, three fireplaces, and dual HVAC systems. The chef's kitchen features Sub-Zero, BlueStar, and Miele appliances, a honed marble island, and leathered soapstone counters, all within an open layout built for indoor-outdoor living. A bedroom and full bath on the main floor offer flexibility for guests or single-level living. Upstairs, the primary suite includes a fireplace, spa-inspired en suite, and soaking tub with sweeping water views, alongside two additional bedrooms, a full bath, and an oversized media room with office/flex space. Highlights include two separate 2-car garages, solar, an updated cabana with water closet and wet bar, custom Ipe deck, and swim spa. Turn-key and move-in ready. Minutes to trails, cafés, Seattle, and Sea-Tac.
