About This Home
only 10 possible out of 800 waterfront offerings – that is how rare this offering is. Sylvan Reach combines two parcels, two waterfronts in a once-in-a-generation waterfront holding on southwest Mercer Island encompassing 200 feet of southwest-facing Lake Washington shoreline across over 3/4 acre from street to water, featuring three docks, two homes, and a log cabin. This extraordinary two-parcel offering delivers rare scale, privacy, and long-term potential. The low-to-mid bank waterfront includes a 65-foot deep-water yacht moorage, a swimming dock, and a 30-foot boat dock. Set among evergreens and frequented by eagles, the land unfolds from elevated outlooks with views toward Mount Rainier down to the water’s edge. Three existing structures—each positioned for privacy and separation—offer immediate use while preserving flexibility for a future legacy vision. Whether reimagined as a singular estate or thoughtfully divided into two substantial homes, the site invites a buyer with patience, creativity, and a long horizon. Accessed by private driveways from both the north and south, the property offers rare seclusion without sacrificing proximity to town, parks, and transit. Enjoy one of the longest arcs of sun in Seattle. Survey and Feasibility for waterfront property available.
