15 Acre Horse Farm and 1 Buildable Residential Lot In the Hamptons, the real value isn't just what you build-it's what you can't replace. Land. As parcels of this size and capability become more limited across the Hamptons, opportunities like this are increasingly rare. This is not simply a horse property-it is a platform for business, growth, and long-term appreciation. Because in this market, acreage isn't just space. Acreage is leverage. In Southampton Town, larger parcels are becoming harder to find and even harder to recreate. This 15-acre Agricultural Reserve captures that scarcity, offering scale, functionality, and long-term positioning in one of the most desirable and lucrative markets in the country. Adding to its flexibility, the property includes a separate 1-acre buildable residential lot-an increasingly valuable component that allows for a private home, future development, or strategic resale. It introduces optionality from day one, giving the next owner multiple ways to unlock value. The property is fully aligned for a working equestrian operation, allowing for boarding, training, and lessons. What would typically require years of approvals and development is already in place, creating a rare opportunity to step into a property that is both operational and scalable. At its center, a 15-stall main barn is designed for efficiency and comfort, with skylit stalls, a wash stall, tack room, and an office complete with a bathroom. Modern upgrades, including heating and air conditioning, support year-round use. Adjacent to the barn, a 20,000-square-foot insulated indoor riding arena allows enjoyment in all seasons, enhanced by natural light and thoughtful construction. Outdoors, the scale of the land continues to define the experience. A 200 by 300 irrigated riding ring provides professional-level training space, while a separate two-acre grass riding field offers additional versatility. Seventeen paddocks, many irrigated, allow for efficient management and rotation. Additional barns expand capacity, supporting a property that can operate at a level well beyond private use. Underlying it all is the infrastructure that transforms acreage into a true asset. Extensive irrigation systems, water access, upgraded electrical service, and supporting improvements are already in place-elements that are increasingly difficult and costly to establish. These are the components that quietly create leverage, turning raw land into something far more valuable.
