About This Home
Opportunity knocks with a rare chance to own one of Mercer Island’s most coveted street-to-water waterfront estates. Set on nearly half an acre edged by 53 feet of prized west-facing shoreline, this extraordinary property captures sweeping views across Lake Washington to the Seattle skyline and Seward Park—arguably among the most breathtaking vistas on the Island. Iconic mid-century design incorporates walls of glass crowned by lofty clear cedar ceilings that frame the ever-changing panorama. Flow out from spacious gathering areas to expansive waterfront terraces. Views continue into the fireside primary suite, while a separate apartment above the main residence offers flexibility for guests, extended living, or future possibilities. Terraced grounds lead down to the water’s edge, beckoning you to swim, boat, entertain, and watch spectacular sunsets paint the sky. Launch days on the lake from your covered dock with two boat lifts, one ready to accommodate a vessel up to 50,000 pounds. Don’t miss the grandfathered boathouse…a rarity that can no longer be replicated! Rich with history from its classic 1950s roots, this is more than just a home—it is a legacy awaiting its next chapter. Whether you choose to enjoy it as-is, thoughtfully renovate, or create your own waterfront masterpiece, the setting is simply irreplaceable. Secure this premier Mercer Island waterfront lifestyle and make new memories for generations to come.
