illionaire William "Bill" Koch is trying to sell his Aspen compound for $125 million, its highest-ever price. The 53-acre estate features a 16,631-square-foot main cabin and various amenities, including hot tubs, hiking trails, and an altitude-acclimation room.

    Koch purchased the property in 2007 for $26.5 million and has since added 31 acres to it. He initially listed the entire property for $100 million in 2015 but dropped the price to $80 million after it didn't sell. Koch was able to sell the additional land for $14.5 million in 2020.

    The estate boasts eight structures, including a 16,600-square-foot main lodge with eight bedrooms and eight bathrooms. The total square footage of all buildings is approximately 25,300. Other amenities include a gym, hiking trails, two hot tubs, and an altitude-acclimation room.

    Koch believes the $125 million asking price is reasonable given that some Aspen homes have sold for around $6,000 per square foot. His listing agent notes that scarcity fuels luxury sales in Aspen's real estate market, creating demand through limited availability.
