About This Home

6425 Undisclosed

A truly exceptional 21-acre waterfront sanctuary, bordered by 16-acres of protected reserve. This island retreat lives like a private arboretum, offering unmatched privacy, natural beauty & sophistication. A meticulous and recent remodel by Christian Grevstad has transformed the residence into a harmonious blend of timeless elegance and contemporary comfort. The property features four thoughtfully designed buildings, incl. a 5,214 sf primary residence, a 2,774 sf 'studio' building, 856 sf guest cottage & 413 sf cabin, for over ~9200 total sf. The grounds are equally remarkable w/ 246' of shoreline, a pickleball court, a walled garden, a reflecting pool and sweeping western views of the Olympic Mts and Puget Sound. Land holdings on Whidbey Island of this significance are scarce, coming around once in a couple generations. Rarer still, is the turn key nature of this offering. The award-worthy Arts & Crafts architecture is impressive in scale yet allow the beauty of the natural setting to take center stage. The contemporary interiors are warm and inviting with subtle touches of European and Scandinavian design sensibilities that will stand the test of time.
