Presenting this legacy waterfront estate for the first time ever. The result of a visionary partnership between Robert Maloney Architects and Thom Schultz / Mercer Builders, this gated European-inspired estate reflects a seamless union of design excellence and masterful construction. Set on over an acre with 100 feet of prime west-facing, no-bank Mercer Island waterfront, offering sweeping lake and city views, a rare private beach, and a dock with boatlift and cover. Arrive via a sweeping, garden-lined drive that winds to an elegant motor court. Exceptionally private and quiet—hidden from the street and neighbors. Inside, timeless architecture evokes grace and grandeur.
