Where Legacy Meets Waterfront Living

Nestled along coveted East Mercer Way, this east-facing waterfront estate offers more than 100 feet of private shoreline with panoramic views of Lake Washington and Mount Rainier. Designed as a custom home with timeless architectural detail and strong bones, the residence presents a rare opportunity: move in and refresh, embark on a luxury remodel, or explore redevelopment potential.

The property includes two primary suites, flexible living areas, and a back wing ideal for a MIL apartment or private quarters with kitchen and baths. A three-car garage with EV charging station, extensive storage, and generous ceiling details reflect the thoughtful design throughout. The gentle slope to the home, calm waters at this end of the island, and quick access north or south along East Mercer Way combine to make the setting both serene and convenient.

Waterfront amenities are exceptional. Ownership conveys 75% of the shared community dock, serving just five homes. This includes two slips on the front and south side, moorage for a 40-foot deep-keel sailboat, an electric lift for an 8,000 pound motorboat, and a 5,300 pound floatplane lift. An auxiliary structure between the subject property and its neighbor provides additional shared storage space.

Adding to its distinction, the home is part of Mercer Island’s historic Appleton community — the site of the island’s first settler in 1885. This heritage lends a sense of permanence and legacy, offering the new owner the chance to carry forward the neighborhood’s tradition while creating a modern vision of waterfront living.

Whether envisioned as a refined remodel, a multi-generational retreat, or a new construction estate, this property represents one of the island’s most compelling opportunities.
