Pristinely and thoughtfully elevated beyond its original design, this gorgeous NW Contemporary strikes a rare balance; modern in form, yet warm, livable, and effortlessly inviting. Expansive yet intentional, the home unfolds through a series of beautifully scaled spaces designed for both connection and retreat. Six ensuite bedrooms offer the ultimate flexibility, suitable for guests or dedicated work-from-home environments, while multiple indoor and outdoor gathering areas create a seamless rhythm for everyday living and entertaining alike. Walls of glass and folding doors dissolve the boundary between inside and out, opening to a level, sun-filled, lush and rarely found at this scale backyard, as well as a view balcony. Covered terraces and open-air spaces invite year-round enjoyment, from quiet mornings to vibrant evenings.The current owner has taken an already exceptional build and refined it further; enhanced landscape design, and integrated AV systems. Tucked on a quiet dead-end street with access to a private beach and the Shore Club's coveted amenities. Minutes to all that is wonderful about Mercer Island; retail, parks, restaurants and sublime commute options to Seattle & Bellevue.
