421 Summit Rd, Walnut Creek, CA 94596

About this home

421 Summit is a custom designed home crafted by architect and designer Dave Ruffin on a spectacular view lot in the Lakewood Community of Walnut Creek. Plenty of thought and care was taken to ensure both the quality of construction and consideration to the land's inherent beauty. The views are private and panoramic - spanning across a multitude of newly constructed decks, retaining walls, and Anderson windows and sliders. This is an entertainers dream in a setting with very little noise - just the rolling hills of a community reminiscent of an Alp setting in Switzerland. See houses in the valley below and enjoy nearby trail heads to Shell Ridge and Mt. Diablo - still a short drive to Downtown Walnut Creek. Vaulted ceilings, skylights, solar tubes, tons of light, designer fixtures, state of the art appliances and a gorgeous walk in closet. Two primary suites upstairs and in-law aupair quarters down below with second kitchenette and entrance. Solar power.
