Set at the end of a Foster City cul-de-sac beside Gull Park, this spacious 4-bedroom waterfront home offers an exceptional lagoon setting. Inside, its split-level, circular layout connects spaces for gathering and retreating. Sunken living and dining rooms welcome you from the foyer, with a sloped ceiling and modernist built-in bookshelves adding architectural character. The kitchen features freshly painted cabinetry, generous storage, water views, and a pass-through breakfast counter connecting to the family room. Sliding glass doors open to an elevated composite deck where lagoon views extend along the channel, across the park, and toward the wider water beyond. Multiple decks, built-in seating, an expansive turf lawn, mature landscaping, and a private floating dock with direct lagoon access combine to create a remarkable waterfront backyard. The primary suite occupies its own level with three closets, an ensuite with an accessible shower and two vanities, plus direct access to a wisteria-wrapped deck. Three additional bedrooms and a shared bath are upstairs. Fresh interior paint, new carpeting, dedicated laundry, half bath, and attached 2-car garage add convenience. Near Audubon Elementary, the Bay Trail levee, Metro Center, dining, shopping, and Hwy 92.
