8243 W Mercer Way, Mercer Island, WA 98040

$5,598,000
Architecturally significant. Unapologetically modern. A definitive Mercer Island statement. Conceived by an architecture professor turned boutique builder, this custom contemporary is a disciplined study in proportion, light, and structure. Cantilevered forms and warm wood tones meet walls of glass, framing sweeping Lake Washington and Mt. Rainier views while dissolving the boundary between indoors and out. The main level unfolds with effortless flow - sunlit living spaces anchored by a refined chef's kitchen and seamless transitions to multiple outdoor retreats. Entertain on the rooftop terrace above the treetops, gather on the covered lounge deck, or unwind in quiet garden-level privacy. Every line is deliberate. Every material chosen for permanence. Upstairs, the primary suite is a private sanctuary with panoramic views and a spa-inspired bath. Three additional bedrooms and skylit gallery corridors complete the upper level with balance and flexibility. The lower level offers a recreation lounge, bonus room, and space for wine storage - ideal for media, work, wellness, or guest quarters. An integrated garage and thoughtful systems elevate daily living with quiet sophistication. Positioned on one of the Island's premier sites with direct proximity to parks, trails, shoreline access, and acclaimed schools, this residence represents a rare alignment of architecture, setting, and lasting value.
