The kitchen opens to the adjoining DR and large family room. The luxurious primary suite is on its own level. Downstairs are 2 BR, a 2nd family room, artist studio, ample storage & separate entrance. The property's beautifully maintained grounds include a nature walk with winding paths leading to a private orchard, a rose garden a meditation area. With parking for 6 cars, ample room to turn around, and an expansive decking area, this home is ideal for hosting parties, holiday gatherings, or just a mid-week get-together with family and friends.
