Amenities include a spectacular indoor pool, full bar, pizza oven, game room, private theater, gym, multiple fireplaces, sauna, and hot tub—creating a true resort-style experience. With 14+ bedrooms, this property has successfully hosted weddings, retreats, and large gatherings.
Nearly every aspect of the home has been thoughtfully upgraded by the current owners. Improvements include a brand new dehumidifier and heater for the indoor pool, new heating and cooling systems, upgraded electric, low-voltage wiring, security cameras, and a brand-new high-capacity septic system. The estate also offers a fully equipped kitchen, a fully equipped game room, a detached garage, and a separate, private suite on the upper level. The entire property is fully winterized and move-in ready.
Zoned RR2, this estate presents exceptional flexibility and investment potential. With planning board approval, it is well-suited for use as a retreat center, summer camp, or event venue. A discerning buyer can enjoy this home as a private luxury escape while also generating substantial income through rentals, weddings, and organizational use throughout the year.
This is truly a property that must be experienced in person to fully appreciate the scale, craftsmanship, and atmosphere it offers—photos simply don’t capture the full picture of what this mansion entails.
