This Mediterranean-villa-inspired property is the kind of home where the good life just seems to grow and grow-much like the 60-year-old Italian grapevines that flourish here, surrounded by beauty on nearly an acre of peaceful, private land in an exclusive enclave with Flatirons views. Each time you return to your circular drive, feel yourself swept away by the breathtaking architecture: tiled rooflines, classic stucco, and pretty pergolas-all backing to quiet greenbelt. Inspired by the owners' two decades in Europe, this home's elegance is unmatched: from the 22-foot ceilings, arching windows and a two-story grand fireplace in the great room to the spectacular kitchen where painted French tiles form a scene of the Proven al countryside beneath a showstopping carved-wood hood. Imagine the unforgettable get-togethers you can host with three ovens, built-in Gaggenau steamer, a dedicated baking station, a warming drawer and Viking appliances. Gather in the spectacular dining room or fling open the 8-foot French doors to the back courtyard that's like something out of Eden with trailing vines, fruit trees, and fragrant evergreens. When downtime is in order, your private primary wing awaits-a sprawling bedroom, luxury bath, and a sunroom anchored by a ficus tree that grows organically into the space! The opposite wing is just as welcoming, with a cozy living room, beautiful secondary bedrooms and baths, and access to a one-bedroom apartment in the walkout basement, ready to rent or convert back to guest quarters or an artist studio with the single turn of a lock. Enjoy incredible energy efficiency thanks to a new HVAC and thermal subflooring that saves hundreds on heating, plus private well- and city-sourced water, a five-bedroom septic system, and prewiring for security and whole-home audio. Consider this your effortless European escape, moments from Boulder, Louisville and Lafayette, with proximity to trails and an utterly serene rural location with views.

Set beneath the ancient sandstone walls of Eldorado Canyon, this extraordinary modern alpine estate was designed by acclaimed architect David Biek, built by master builder Kevin Cowan, featured in Colorado Homes and Lifestyles magazine, and televised on the Lynnette Jennings Show. Exceptional stonework, patinaed copper, rich hickory and beech floors, & soaring ceilings make the architecture feel alive with intention - a home that belongs to its canyon as completely as the ancient rock above. Step inside: radiant-heated floors underfoot, canyon light flooding through enormous windows. Two stained glass windows bracket the day - morning light pours across the great room wall at sunrise; the west-facing sunset window in the solarium off the crafting loft closes the day in warm color. Three bedrooms, two full baths, & powder. Carlos Steybe's cherry millwork fills every turn. The great room's soaring 25-foot stone fireplace commands the space; the family room hearth burns wood. The chef's kitchen: floor-to-ceiling pantry, Sub-Zero, dual Wolf ranges, Bosch dishwasher, built-in cherry breakfast table. The dining room holds a Steybe-built table and chairs alongside his cherry hutches. The third-floor sanctuary: beech floors, walls of glass, two private patios to the canyon - office, meditation room, or yoga studio. The owner has kept bees on the roof, where the air is clean,& the world falls quietly below. Walk the labyrinth at dusk - plumbed for water and gas, awaiting your vision of fire & flow. Harvest from the biodynamic garden, entertain in the outdoor kitchen, soak in the hot tub under a wide Colorado sky. Eldorado Springs water flows to every faucet & shower. An ancillary building houses the wine cellar - vendange table, bench seating, 3,000+ bottles behind artisan copper doors - & a recording studio with acoustic baffling & beech floors. The non-conforming guest cottage, wood shop, open garden shed, & large storage shed complete this once-in-a-generation estate.
