Single Family Home for sale in Mercer Island, WA

for $2,499,000 with 4 bedrooms and 4 full baths, 1 half bath. This 4,114 square foot home was built in 1960 on a lot size of 0.4751.

Set along one of Mercer Island's most coveted streets, this Northwest Contemporary feels grown from its own hillside, where sweeping west facing views of Lake Washington, Seattle, and the mountains beyond become part of every room. Built in 1960 and thoughtfully expanded, it carries the intricate woodwork of its era with the ease and light of a home designed for today. Pass the detached garage and follow the lush landscaping toward a facade of expansive windows. Inside, soaring vaulted ceilings draw in the light and that luminous western view in one sweep. A sheltered space off the entry offers a home office or reading room, while the formal dining room frames the water and mountains beautifully. A generous fireplace anchors the living and dining rooms, and the updated kitchen blends seamlessly with the home's warm, natural palette. A later addition brought two serene bedrooms, each with its own en-suite bath. Downstairs, an additional bedroom and bath, a spacious rec room, and the primary suite await, the latter a true retreat with exceptional woodwork and a private sauna. In all, 4,040 square feet of finished living space span four bedrooms and four and a half baths. Outside, over 20,000 square feet of land wraps the home in gardens and open sky, with the lake and city glowing at sunset. A large shed offers quiet possibility for a gardener or a detached office. This is a home that lives in harmony with nature, an invitation to slow down and savor the light.
