Tucked away on approximately 2.54 acres in Stone Ridge, Stillwater is a bright, character-rich 1980 Green Mountain Homes passive-solar house with an unusual concentration of systems already in place: owned grid-tied solar with working battery backup that can power designated household loads during outages, multiple heating and cooling options, private well and septic, protected growing space, mature gardens, a woodstove, and a powered two-story garage/barn. The result is a house that feels like both a beautiful, design-forward country home and a deeply capable, climate-conscious property -- comfortable, redundant, and ready for the future we're already living in. The house was designed from the beginning to work with its site, using passive solar, thermal mass, an original Solar Slab and circulation system to capture, hold and move warmth through the home. Today that remarkably forward-thinking design is layered with owned, net-metered solar with working battery backup, a three-zone Fujitsu heat-pump system, wood heat, electric heat, and ceiling fans. Private well and septic add another layer of independence, and the well pump is included among the home's historically battery-backed loads. In other words: multiple ways to heat, cool, power and supply the house rather than dependence on a single system or solely on the grid. The 2,037-square-foot interior is warm, light-filled and quietly stylish, with large windows, skylights, built-in bookshelves, a first-floor bedroom and laundry, two generous upstairs bedrooms, and an easy connection to the landscape from nearly every room. The screened porch creates the perfect sheltered outdoor room, while the sunroom roof and skylights were replaced in 2026. Outside, decades of gardening have created mature perennial and composted pollinator beds, flowering trees and shrubs, herbs, grasses and productive growing areas. During the current ownership, extensive overgrowth and dangerous trees were removed, full-sun growing space was reclaimed, beds were repeatedly enriched with compost, and approximately 1,000 additional native, perennial, pollinator and ornamental plants were added. Approximately one acre around the house, gardens, lawn and principal growing areas is protected by an 8-foot deer fence, creating unusually usable country acreage for gardens, pets and food growing. A wraparound deck and screened porch make outdoor living easy, while the powered two-story garage/barn offers substantial space for vehicles, tools, equipment, workshop use, storage or creative projects. And none of this requires disappearing into the wilderness. Spectrum internet supports serious work-from-home use, while Stone Ridge, High Falls, the Ashokan Reservoir, Kingston, Woodstock, restaurants, markets, trails and swimming are all close at hand. Stillwater is a beautiful refuge for the world as it is: a design-forward country house with mature land, serious infrastructure and more independence built in. Future-proof without austerity. Country living without giving up the good life. The property also comes with an unusually deep archive of original plans, manuals, solar documentation and house records for its next steward. Please note: existing public tax records indicate 2.3 acres; the seller holds a filed lot-line revision map reflecting approximately 2.54 acres.
