About This Home
PRICE IMPROVEMENT! There is still time to spend your summer playing on sparkling Lake Washington! With a tempting new price, opportunity beckons you to seize this rare chance to own a west-facing waterfront estate on Mercer Island's premier Gold Coast. Its exceptional street-to-water lot encompasses nearly half an acre edged by 53 feet of prized western shoreline. You’ll savor front row views across the lake to the Seattle skyline and Seward Park, arguably among the most breathtaking vistas on the Island. Fully rebuilt in 2017, the massive, covered dock is a boater's dream complete with two boat lifts—one ready to accommodate a vessel up to 50,000 pounds. A grandfathered boathouse at the water's edge is a true rarity that can no longer be replicated under today's shoreline regulations. After a day making memories out on the lake, colorful sunsets carry you home to your waterside lawn and beautifully terraced walkway leading up to even more views from the house. The main residence plus a separate apartment above are offered as a blank canvas ready for your vision…whether that's a thoughtful renovation of the original mid-century design, or a ground-up rebuild to fully capture this irreplaceable setting. Add your signature style and create a new legacy to be loved for generations to come. Waterfront aficionados will recognize this extraordinary, diamond in the rough prospect to secure incredible views, coveted waterfront, and a boater's dock that simply can't be recreated.
