Welcome to the Mount Guardian Modern. Positioned on nearly four acres on Mount Guardian, this Woodstock contemporary is the rare new construction that gets everything right: the siting, the light, the materials, the silence. Completed in 2021, it offers three bedrooms, three bathrooms, and 2,064 square feet of architecture that feels both intentional and effortless, anchored by a first-floor primary suite and oriented to capture the great room's double-height views and the surrounding landscape throughout the day. Steel-framed sliding doors open onto the main living spaces, leading to a grand bluestone patio where the eye settles on seasonal views of Mount Tobias and the property's cultivated gardens. The transition between interior and exterior spaces is seamless by design. Clean architectural lines and expansive glazing ensure the landscape remains a constant presence. The kitchen is refined and practical in equal measure, with warm wood cabinetry, stone countertops, and an induction range. A Herman Miller pendant light anchors the dining area with quiet authority. Throughout the home, natural materials and thoughtful proportions create a sense of balance in which nothing feels superfluous. The Mount Guardian Modern was built to passive house standards with triple-pane windows, an insulated concrete-slab foundation, and whole-house ERV ventilation. The home operates entirely on electricity with no oil or gas and was designed for superior insulation, efficiency, and year-round comfort. A generator connects directly to the electrical panel, ensuring continuity regardless of circumstance. Smart home integration extends to climate, ventilation, hot water, security, and motorized shades on the principal windows. All systems can be monitored and managed remotely while operating quietly in the background. What further distinguishes this property is its infrastructure. Underground electric conduits and water lines extend to both sides of the home in anticipation of a pool, garage, or expanded exterior amenities. The attic conduit has already been installed for future solar. The oversized 1,250-gallon septic system allows for the addition of another bathroom, likely within a future studio above a garage. The groundwork for what comes next has already been thoughtfully laid. At the top of the road, a trail leads directly to the summit of Mount Guardian and its sweeping views over Cooper Lake. The wood-fired sauna awaits your return. Private, trail adjacent, and architecturally resolved, The Mount Guardian Modern offers a rare expression of contemporary Hudson Valley living. A 3D Walkthrough Tour is available in the digital Lookbook or by request.
