Set on approximately 6.5 private acres within Starwood, Aspen's only gated community with 24-hour security and its own on-site fire station, 401 Carroll Drive stands as one of the most significant newly constructed estates delivered in Aspen in recent years. Completed in 2026 after more than five years of thoughtful design, permitting, and construction, the property offers exceptional privacy, security, and sweeping 180-degree views across the Elk Mountains and all four Aspen Snowmass ski areas. Encompassing nearly 15,000 total square feet, the residence offers a level of scale, acreage, and amenity depth that cannot be recreated under current Pitkin County land-use regulations and energy codes, making it an exceptionally rare opportunity within Aspen's tightly constrained market. Designed by KA DesignWorks, with interiors by Studio 133 and construction by Janckila Construction, the home combines architectural clarity with modern livability. Expansive walls of glass frame the surrounding mountains, while seamless indoor-outdoor spaces create an environment equally suited to private retreat or large-scale entertaining. At the heart of the home is a resort-caliber wellness center 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 extensive outdoor living areas enhanced by nearly 4,500 square feet of snowmelt systems, providing effortless year-round access. The estate includes seven en-suite bedrooms, highlighted by a primary suite designed as a private sanctuary with unobstructed views and direct terrace access. A separate two-bedroom Caretaker Dwelling Unit (CDU) offers flexibility for guests or staff. Engineered for both immediate enjoyment and long-term resilience, the home incorporates solar generation, battery backup, and advanced infrastructure systems. Finished, furnished, and ready for immediate occupancy with Certificate of Occupancy in hand, 401 Carroll Drive offers a rare combination of acreage, security, privacy, views, and resort-level amenities within Aspen's most exclusive gated enclave. Recently featured in Robb Report, The Resident, and multiple international outlets, the estate has been recognized as one of Aspen's most significant new residential offerings.
