Buttermilk Mountain, Colorado, United States
Set on approximately 6.5 naturally 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 meticulous design, permitting, and construction, the property offers exceptional privacy, security, and sweeping 180-degree views of the Elk Mountains and all four Aspen Snowmass ski areas. Encompassing over 15,000 square feet, the residence combines scale, acreage, and an amenity-rich program that cannot be replicated under current Pitkin County land-use regulations and energy codes, making it an exceptionally rare opportunity in Aspen’s tightly constrained market. 401 Carroll offers more than an extraordinary Aspen lifestyle; it represents a strategic store of value in a low–property tax state, at a time when many ultra-high-net-worth individuals are reevaluating high-tax environments such as New York and California. Envisioned by award-winning developer Whitecap Designs and brought to life by award-winning architect KA DesignWorks, with interiors by Studio 133 and construction by Janckila Construction, this home seamlessly blends architectural clarity with modern livability. Expansive walls of glass frame the surrounding mountains, while fluid indoor-outdoor spaces create an ideal setting for both intimate retreats and largescale entertaining. At the heart of the home lies a resort-caliber wellness sanctuary, showcasing a heated swimming pool with integrated spa, fully equipped fitness gym, steam room, infrared sauna, cold plunge, and a dedicated massage room. Complementary lifestyle amenities include a private theater, wine room, executive office, cabana lounge, and expansive outdoor living areas, all enhanced by nearly 4,500 square feet of snowmelt systems for 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 access to the terrace. 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 features solar generation, battery backup, and advanced infrastructure systems. Finished, furnished, and ready for immediate occupancy with a Certificate of Occupancy in hand, 401 Carroll Drive offers a rare combination of acreage, security, privacy, views, and resort-caliber amenities within Aspen’s most exclusive gated enclave. Recently featured in Robb Report, The Resident, and multiple international outlets, this estate is widely recognized as one of Aspen’s most significant new residential offerings.
