for $3,200,000 with 5 bedrooms and 4 full baths, 1 half bath. This 6,216 square foot home was built in 1985 on a lot size of 13.2.
Just 60 minutes from Manhattan, this exceptional Hudson Highlands retreat offers a rare combination of architectural character, protected natural surroundings, and direct access to some of the region’s most celebrated outdoor destinations. Set on 13 private acres across two separate lots—including a second vacant, buildable parcel—the property is tucked away on a quiet dirt road known for its strong sense of community, minimal traffic, and remarkable tranquility. Bordering the 8,000-acre Hudson Highlands State Park Preserve with more than 70 miles of trails, the estate enjoys a setting that feels both deeply secluded and endlessly connected to nature. Outdoor recreation begins at your doorstep. The property features its own trail network and private trailhead connecting directly to the Appalachian Trail, offering true hike-on, hike-off access. Walk to nearby lakes, explore the trails of the Russel Wright Design Center, hike to Anthony’s Nose, or cycle directly from the property to Bear Mountain, one of the Northeast’s premier road biking destinations. A seasonal stream, private campsite, and campfire area further enhance the experience of living immersed in the landscape. Designed by noted Hudson Valley architect Frank Dushin, the residence blends the warmth and craftsmanship of the Arts and Crafts tradition with the clean lines and thoughtful spatial design of modernism. Dramatic exposed beams, natural materials, and a striking sunken living room create spaces that feel both timeless and distinctly connected to their surroundings. The home has been extensively renovated, including a complete reimagining of the primary suite and bath, beautifully updated bathrooms throughout, and a thoughtfully designed laundry room. Two fireplaces, a screened porch, and expansive views of the surrounding gardens and woodlands create inviting spaces for every season. Outside, more than two decades of garden design by a beloved local horticulturist have shaped the landscape into a living extension of the home. Mature plantings, curated garden rooms, and woodland paths unfold across the property, creating beauty and interest throughout the year. A separate wellness pavilion includes a gym, steam room, dedicated shower facilities, outdoor hot tub, and connections for a future sauna, while a detached two-bedroom guest house with its own kitchen offers comfortable accommodations for family and visitors. Rarely does a property combine architectural pedigree, buildable acreage, direct trail access, protected parkland, established gardens, and resort-style amenities so close to New York City. This is a true Hudson Highlands sanctuary—private, peaceful, and connected to the landscape in every direction.
