About This Home
Hidden away on nearly an acre of lush grounds overlooking Lake Washington, this private sanctuary awaits you. Pass through the gates & you'll find serene luxury at every turn. Step into an opulent foyer w/ dual staircases ascending to a glittering chandelier. The spaces beyond are both elegant & inviting, from the wood-trimmed, fireside offices to voluminous gathering spaces that spill out to an expansive chateau-inspired terrace. Generously placed windows bring lake views into nearly every room. Epicureans will delight in the remodeled kitchen, well-appointed with slab granite surfaces, commercial grade Miele/Viking/SubZero appliances, Murano glass lighting, a walk-in pantry & a massive center island with seating bar. Cherry hardwoods flow into the adjacent dining nook & comfy living room. Discover ultimate flex-space on the lower level with a rec room, wet bar, game room, theater, wine cellar, & guest suite. Upstairs, your primary suite is a true retreat offering a sitting area, dual-sided fireplace, palatial 5-piece bath, dream walk-in closet, and French doors opening to your own lake view balcony. Five bedrooms + many bonus areas provide ample space & privacy for all. Extras include 22 skylights for maximum light, fresh paint & carpeting, and all new electrical & EV charging. Make the most of sunny days with a variety of outdoor living areas & level lawns, or explore options for potential subdivision (buyer to verify). An ideally situated gem that checks all the boxes!
