About this home
This Northwest gem is hidden away in a magical forest setting just steps from the beach. Its iconic A-frame design combines the best of an open-concept floor plan and inviting living areas, with the lofted primary bedroom and the living/dining spaces both illuminated by a wall of windows facing Lake Washington. Soaring, cedar-beamed ceilings lend a sense of spaciousness that still feels snug and inviting. Spend cool evenings basking in the warmth of the wood stove. Cooks will appreciate the 5-burner Samsung gas stove and Fisher Paykel refrigerator. The kitchen counter opens to the vaulted dining area for easy entertaining. Two spacious main floor bedrooms in addition to the large primary loft provide extra room to spread out or work from home. Sunny days beckon you out to the expansive deck... You’ll be enchanted by the picturesque privacy and glimpses of the lake, with a treehouse feel straight out of your childhood dreams. Don’t miss the ADU potential on this large lot. Surrounded by such serenity, it’s easy to forget how close you are to top-rated schools, shopping, restaurants, and easy I-90/light rail access to Seattle or Bellevue. Rarely do you find a secret oasis in such a prime location!
