About this property
Experience a forest sanctuary on Vashon Island’s serene west side. This custom built northwest contemporary home is set on a shy five-acre parcel surrounded by a sunny meadow, lush landscaping, kitchen garden, established orchard, and groomed walking trails through the woods. The well-built home bridges indoor and outdoor spaces with soaring windows and a spacious deck. Enjoy ample living spaces and one bedroom on the main, with another two bedrooms upstairs. The property offers the ultimate maker-space, a magnificent 24’ X 36’ shop building, with attached 24’ X 24’ double-height garage – ready for an artist, wood-worker, or business-owner. The gated entry, cross-fencing, and fenced animal shelter are ready for your hobby farm or companion pets. There are a few tucked away, secret flex spaces - think offices or studio space. A portion of the property is classified as Open Space - a property tax benefit - and is served by an excellent two-party water system. Privacy, space for everyone and all their projects – your new home!
