Tucked away on Mt. Helix, this John Mortenson original was designed to integrate into the landscape, with a sweeping roofline, deep overhangs, and walls of glass framing the canyon beyond. Step inside and the space soars. The living room opens beneath a cathedral ceiling, with wall-to-wall windows and a commanding fireplace at its heart, flowing into the dining area and a beautifully remodeled, vaulted eat-in kitchen. Evenings are made for watching the sun drop over the western hills. The home offers 3 bedrooms, 3.5 tastefully remodeled baths, and approx. 2,800 sq ft. The primary suite is a true retreat, with canyon views and a private spa just steps away. Outside, the pool, sun deck, fire pit, and gazebo for alfresco dining set the stage for unforgettable gatherings, all wrapped in the privacy of lush, tranquil gardens. Paid-off solar, 2-car garage, RV parking, and total serenity. A mid-century design legacy you can't recreate. Competitively priced. Schedule your private tour today!
