105 Sand Hill Road

The Geosphere is a convergence of visionary design, tactical investment and natural sanctuary. Set on 7.18 secluded acres in the heart of Dover Plains, this fully legal, architect-designed geodesic residence and studio building give you something unmistakably distinctive: a home that feels like art, and a property that can perform like an asset. Inside, the striking residence is fully winterized, featuring commanding glass and skylights, a custom-crafted interior and a cozy wood stove that makes efficiency luxurious. The main geodesic dome is complemented by a studio seamlessly integrated into the landscape — perfect for an art studio, office, or workspace. The infrastructure is robust: on-grid power with off-grid capability, a dedicated well and full septic system. A spring-fed natural swimming pond, aerated and stocked with fish, doubles as a functional fire-safety reservoir (an insurance-advantage you rarely see). A new half-mile gravel driveway ensures privacy and serenity from the main road. Zoned and fully permitted as a short-term rental through Dutchess County, The Geosphere Retreat is income-ready if that is what you seek. Comparable homes in the region are generating $1,000–$2,000 per week. With further subdivision potential (2-acre minimum lots), and agricultural tax incentives available, this isn’t just a home — it’s a platform for both current income potential—and future upside. Positioned in Dover, NY, two hours from New York City, in an area where growth is quietly gathering pace, including nearby Silo Ridge, and One&Only in development, complete with commuter-link access via Metro-North’s Harlem Line. The Geosphere awaits to deliver a statement, a sanctuary, and a truly unique value proposition.
