A 10,000-square-foot Vermont mansion featuring an underground tunnel, a reinforced vault, and multiple "secret rooms" is going to auction with no minimum bid and no reserve.
The property, known as The Preserve at Wade Pasture, is located in Stowe, Vermont, within the exclusive Robinson Springs enclave. Adam and Sarah Hergenrother, the homeowners, are opting for an auction format after the estate did not sell at its previous asking price.
The estate was initially listed for $15.8 million in June 2025 and was later reduced to $15 million before the owners decided to pursue an auction.
The residence, built in 2024, includes five bedrooms and eight bathrooms. A key feature is a climate-controlled underground tunnel that connects the main house to a 7,000-square-foot sports barn. This barn is equipped with heated turf for year-round recreation, such as tennis, pickleball, and golf.
Among the property's amenities are an outdoor court suitable for tennis, pickleball, or basketball, a heated swimming pool with a natural stone wall, a winter sledding hill, and a spring-fed swimming pond with a diving rock. The primary suite on the first floor offers views of the surrounding nature and includes a spa-like bathroom. A hidden door in the primary suite provides access to the underground tunnel.
The estate also boasts an epicurean kitchen with high-end appliances, a quartz waterfall island, and seamless flow to outdoor living spaces via accordion glass doors. The contemporary basement houses a "Nordic-inspired wellness wing" with a full gym, infrared sauna, and a Tonal system.
High-security features include four secret rooms and a reinforced concrete vault. The property also contains an executive office, a three-sided fireplace, and a 1,300-square-foot guest apartment.
Constructed with commercial-grade timber and featuring Douglas fir beams, the home incorporates a Crestron smart-home automation system. Storage facilities include a heated three-car garage and a detached two-car garage.
The 11.6-acre property offers clear views of Mount Mansfield and is located approximately 10 minutes from Stowe Mountain Resort. Stacey Torrey, vice president of Integrity Luxury Real Estate Auctions, described the property as a "legacy property" designed for generations of family gatherings and recreation, emphasizing its unique craftsmanship, privacy, and lifestyle.
