A true architectural tour de force, this newly completed Mountain Ridge estate redefines modern luxury against one of Boulder's most breathtaking natural backdrops. Designed by award-winning Studio B, with interiors by Studio Brother John and landscaping by Evoke, this striking residence rests on a premier, private three-acre lot bordered by over 6,300 acres of protected open space in the gated Mountain Ridge community. Floor-to-ceiling architectural-grade windows frame unobstructed vistas stretching from the Flatirons to Pikes Peak, the Denver skyline and the eastern plains, immersing every space in light, sky and landscape. The expansive layout offers en-suite baths throughout, an inspiring office or lounge and a flexible lower level ideal for fitness, media or recreation. Interiors showcase globally sourced finishes, including European white oak floors from France, sculptural Cocoon fixtures from Holland, custom white oak cabinetry by BKI Millwork and a chef's kitchen appointed with Gaggenau and Miele appliances. Outdoor living is equally extraordinary, featuring a dining deck, stainless steel hot tub and sunken conversation pit perfectly positioned for sunrise and sunset views. Sustainable, intelligent and impeccably crafted by Morningstar Homes, this residence is more than a home - it is a refined expression of design, privacy and Boulder's unmatched natural beauty.
