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. View this listing at: http://donnamariechaimanis.laffey.com/mls=932753
