An Irreplaceable Aspen Legacy Estate. In Aspen, true scarcity is defined not by price, but by what can no longer be recreated.Now completed after more than five years of design, permitting, and construction, 401 Carroll Drive stands as one of the most significant newly built estates ever delivered in Aspen. Located within Starwood, Aspen’s only gated community, the property spans approximately 6.5 acres of naturally private land, offering exceptional security, seclusion, and panoramic views across the Elk Mountains and all four Aspen Snowmass ski areas.Encompassing nearly 15,000 total square feet, the residence represents a level of scale, acreage, and amenity depth that is no longer achievable under current land-use regulations. It is, by definition, a generational opportunity. Designed by KA DesignWorks, with interiors by Studio 133 and constructed by Janckila Construction, the home balances architectural clarity with exceptional livability. Walls of glass frame uninterrupted mountain views, while seamless indoor-outdoor spaces create an environment equally suited to private retreat or large-scale entertaining.At its core is a complete wellness center rivaling the world’s finest resorts, featuring a heated swimming pool with integrated spa, fitness gym, steam room, infrared sauna, cold plunge, and dedicated massage room. Additional amenities include a private theater, wine room, executive office, cabana lounge, and expansive outdoor living environments enhanced by nearly 4,500 square feet of snowmelt. Seven en-suite bedrooms provide exceptional accommodations, including a primary suite designed as a private sanctuary with unobstructed views and direct terrace access. A separate two-bedroom CDU offers flexibility for guests or staff.Engineered for both immediate enjoyment and long-term resilience, the estate includes solar generation, battery backup, and advanced infrastructure systems. Within Aspen’s tightly constrained and globally sought-after market, properties of this scale, privacy, and permanence are extraordinarily rare. 401 Carroll Drive is not simply a newly built home. It is a legacy estate, impossible to recreate and positioned to endure for generations. Recently featured in Robb Report, The Resident, and international media as one of Aspen’s most significant new estate offerings.
