A rare opportunity to own one of Boulder County's most private and architecturally distinctive estates, set on nearly 3 acres directly bordering protected Open Space with unobstructed views that will never change. Extensively remodeled in 2025/2026, this Spanish-inspired retreat blends Santa Fe design with elevated modern finishes across approximately 5,800 square feet.

Behind a gated entrance, three enclosed courtyards create a resort-style experience, four secluded patios, all offering seamless indoor-outdoor living, incredible natural light, and unmatched privacy. Inside, soaring 10 to 12 foot ceilings with log beam and latilla detail set the tone, complemented by a rich mix of sandstone, tile, and antique distressed pine and oak wood flooring.

Eight fireplaces, custom cabinetry, and stone and quartz surfaces deliver warmth and craftsmanship throughout. The upper main level features a beautifully updated kitchen, multiple living and dining spaces, a solarium, and a private guest suite with its own kitchen and bath, ideal for multigenerational living or long-term guests.

The main levels expand the lifestyle with a four car garage with copper clad doors, multiple offices/rooms, game and hobby spaces, sauna, and a secure walk-in safe room. The primary suite is a true escape, complete with a private library, hidden storage, spa-inspired bath with steam shower and soaking tub, and a dedicated jacuzzi and workout room.
