for $1,990,000 with 3 bedrooms and 3 full baths, 2 half baths. This 3,821 square foot home was built in 2007 on a lot size of 0.98.
Perched above Boulder with sweeping 180-degree mountain views, this architect-designed modern retreat offers a rare combination of striking contemporary design, privacy, and functionality-just approximately 20 minutes from downtown Boulder. Designed by an architect for personal use, the home was thoughtfully crafted to maximize natural light, passive solar efficiency, and seamless indoor-outdoor living. Walls of commercial-grade glass and oversized triple sliding doors frame unobstructed views from nearly every room, while southern exposure fills the home with warmth and sunlight year-round. The chef's kitchen features Bosch appliances, an induction cooktop, Carrara marble and granite countertops, and opens effortlessly to expansive dining and living spaces designed for entertaining against a dramatic mountain backdrop. The flexible floor plan includes private en-suite bedrooms, multiple office spaces, and a remarkable studio suite with soaring 11-foot ceilings, abundant natural light, kitchenette, bathroom, 240V outlet, separate entrance, and potential for a media room, guest quarters or creative workspace. The primary suite offers a secluded deck with breathtaking views, while outdoor living is elevated with a large terraced patio, gas fire pit, and established aspen grove with underground drip irrigation. Additional features include in-floor radiant heat, metal roof, double garage with covered parking, wildfire defensible-space approval, and a peaceful mountain setting that blends modern architecture with the beauty of Colorado nature.
