An artisanal masterpiece designed to elevate everyday living and a love for the lake. Designed by Studio McGee and built by Lochwood-Lozier Custom Homes, this waterfront estate occupies a coveted position along Mercer Island’s Gold Coast, capturing all-day sun, western sunsets, and views across Lake Washington to Seward Park. Set on 86 feet of street-to-water frontage, the property features level lawn to the water’s edge, a private swim cove, sports court, and new Seaborn dock with power, water, lighting and lift ready infastructure. From afternoons on the dock to evenings watching boats drift across the lake, the home embodies waterfront living. The Traditional Heritage architecture embraces Calcutta marble, white oak herringbone and wide-plank floors, custom millwork, copper accents, and natural stone. Michelin level entertaining kitchen with hidden scullery and working pantry anchors the home for dinners or large scale events. The primary suite offers a sanctuary with custom boutique level dressing room, while a wellness retreat includes a fitness studio, sauna, and lakeside bath. A chilled glass wine gallery, library, dual offices, bonus spaces, and en-suite bedrooms provide flexibility. Covered heated outdoor rooms, outdoor kitchen, Crestron automation, solar, Generac backup power, and three-car garage complete this legacy estate on one of Mercer Island’s sought-after stretches of waterfront.
