This extraordinary Mercer Island waterfront residence stands as a testament to what's possible when visionary architecture meets meticulous craft. Originally built in 1916, the home has been completely reimagined — preserving the soul of a century-old landmark while delivering modern luxury for today's most discerning buyer. Set behind a private gate, the property commands 40 feet of Lake Washington bulkhead waterfront and sweeping water views. Four bedrooms, three luxurious baths plus a powder room, and open kitchen, living, and dining areas are finished with interiors curated down to the last detail. There's a rhythm to living on Mercer Island you don't fully understand until you've experienced it — the stillness of Lake Washington at first light, water against the dock before the world wakes, an evening boat ride as the sky turns pink. A stone paver patio with plunge pool and spa is perched above the lawn, alongside a classic boathouse that invites life on the lake from the moment you arrive. Launch at dawn or host at sunset — this is a rare stage for either. Mercer Island is connected by I-90 to Seattle and the Eastside yet genuinely removed from the pace of both — top-ranked schools, a walkable downtown, neighbors who know your name. Properties of this caliber — historic pedigree, true waterfront with boathouse — are not built anymore. They are restored, once, by people who care deeply. This is that home.
