Welcome to a rare fusion of modern European elegance and Colorado farmland serenity. Set on 22 sweeping acres with 10 Class A Shares of Boulder White Rock Ditch, this 2023-built estate delivers a lifestyle as dynamic as it is luxurious. Every detail has been crafted for impact-from the dramatic Austin white stone wall with its now-iconic mantel to the soaring great room where 24-foot panoramic glass doors dissolve into a horizon-wide view of the Rockies. Inside, the home strikes a perfect balance of sophistication and comfort. Four spacious bedrooms, six spa-inspired baths, and playful built-in bunk beds ensure there's space for everyone. Smart living is effortless here with Control4 home automation managing Thermador appliances, climate, and security. The primary suite is a private sanctuary with gauzy, switchable privacy glass, while a hidden wine cellar, secure vault, and custom steel doors add intrigue at every turn. Function meets flair in the details: two laundry rooms for convenience, a half-bath vanity crafted from the property's original cattle corral, and sustainability woven throughout with passive/active solar systems and a brand-new irrigation network-tractor included. Head outside to discover an entertainer's paradise. The outdoor kitchen gleams with stone and quartz counters, drink fridge, firepit, and TV hookups, making it the go-to gathering place. Surrounded by conservation easements (without being tied to one), the property offers uninterrupted privacy and open space in every direction.This isn't just a home-it's a statement. A place where heritage and innovation meet, where wide-open spaces frame mountain vistas, and where modern design creates a legacy for generations. Experience Colorado living at its most vibrant, purposeful, and unforgettable. LIVE BOLDER, LOVE BOULDER!
