Billionaire Bill Koch Lists Expansive Aspen Estate for $125 Million
Billionaire businessman and renowned art collector Bill Koch has officially put his luxurious Elk Mountain Lodge estate in Aspen, Colorado, on the market for $125 million. Spanning 52 acres in a stunning alpine valley, the estate offers an extraordinary combination of privacy, natural beauty, and high-end amenities—an exclusive retreat for those seeking the ultimate mountain escape.
A Prime Location with Breathtaking Views
Located just 10 miles from downtown Aspen, this sprawling property boasts panoramic views of the Elk Mountains and Castle Creek, creating an unparalleled setting for outdoor adventure and sophisticated living. Koch originally purchased the estate in 2007 for $26.5 million. Once a working dude ranch, the property was transformed into a private luxury compound under his ownership. After expanding it by acquiring an additional 31 acres, Koch first listed the estate in 2015 for $100 million, later reducing it to $80 million. In 2020, he sold a portion of the land for $14.5 million, leaving the current 52-acre parcel, which was previously available as a luxury rental for $35,000 per night or $300,000 per week.
A Masterpiece of Mountain Architecture
Elk Mountain Lodge is a showcase of refined craftsmanship and rustic elegance. At the heart of the estate is a 16,600-square-foot main lodge featuring seven bedrooms and eight bathrooms. The interiors highlight natural materials and grand design, with flagstone floors, soaring 30-foot vaulted ceilings, wood-paneled walls, and multiple fireplaces that add warmth and sophistication.
The property includes an elegant 20-seat dining room, perfect for hosting grand gatherings, and a climate-controlled wine cellar to preserve a world-class collection. Additional features include two studies, a state-of-the-art screening room that doubles as an altitude-acclimation chamber, and floor-to-ceiling windows that frame breathtaking mountain views.
Beyond the main lodge, the estate includes seven guest cabins, bringing the total living space to nearly 25,300 square feet, with 14 bedrooms and 17 bathrooms. One of the cabins serves as a fully equipped gym, while others offer private accommodations for family and guests.
An Outdoor Enthusiast’s Paradise
Designed for those who love the outdoors, the estate offers endless recreational opportunities. The property features two hot tubs, private ponds, and miles of scenic hiking and cross-country skiing trails, ensuring year-round adventure.
Nestled along Rooney Circle, a private road named after Koch’s wife, Bridget Rooney Koch, the estate provides unmatched privacy while remaining close to Aspen’s world-class dining, shopping, and cultural attractions.
A Rare Opportunity in Aspen’s Luxury Market
Bill Koch, a member of the ultra-wealthy Koch family and founder of Oxbow Carbon Corporation, is no stranger to high-end real estate. Along with Elk Mountain Lodge, he owns properties in New York City, Palm Beach, and Cape Cod. He also owns Bear Ranch, a 4,500-acre estate in Paonia, Colorado, where he has created a replica of an Old West town, reflecting his deep appreciation for history and preservation.
Koch and his wife are selling Elk Mountain Lodge as they transition into a new stage of life, now that their children have grown. With Aspen’s luxury real estate market surging—median sale prices have skyrocketed from $4.95 million in 2016 to $13.23 million in 2024—he sees this as the perfect moment to pass the estate on to its next owner.
An Exclusive Chance to Own a Piece of Aspen’s Elite Landscape
With its breathtaking setting, expansive living spaces, and top-tier amenities, Elk Mountain Lodge is more than just a home—it’s a legacy property. Whether serving as a private mountain retreat, a family compound, or a trophy estate, this Aspen masterpiece represents a once-in-a-generation opportunity to own a luxurious escape in one of the world’s most desirable destinations.
