Perched above the Roaring Fork Valley on 1.63 private acres in the gated community of Elk Springs, this striking 4-bedroom, 4.5-bath custom-engineered ICF concrete home offers 4,604 sq ft of thoughtfully designed living across three levels. Featured in a national builder/architect magazine for its energy efficiency, fire resistance, and soundproofing, this home is as functional as it is beautiful. Cement floors with radiant heat flow throughout both levels, keeping the home warm and efficient year-round. The main level showcases sweeping Mt. Sopris views from the living room and kitchen, vaulted ceilings, and spacious wraparound decks and patio areas perfect for outdoor entertaining and relaxing in the mountain air. The primary bedroom and a flexible bonus room -- easily a 5th bedroom -- round out the main level. The ground level includes 3 bedrooms, 2 bathrooms, a kitchenette, and a remodeled living and dining area with separate wheelchair-accessible access and its own patio space. A large heated 3-car garage provides generous parking and storage, and the corner lot adjoins HOA open space for exceptional privacy. Since 2020, sellers have invested extensively in upgrades including a new boiler and hydronic heating system, Level 2 EV charger, fresh interior paint, new garage door opener, water softener, and professional fire-proofing. A rare combination of architectural distinction, mountain resilience, and move-in-ready condition -- just 15 minutes to downtown Glenwood Springs or Carbondale and 45 minutes to Aspen/Snowmass ski resorts.
