Bellwether Farm - A Rare Compound Opportunity in the Heart of Bedford Horse Country.
Bellwether Farm presents a singular opportunity to create a fully bespoke country estate on Mt. Holly Road, one of Northern Westchester's most coveted addresses in the heart of Bedford-Katonah horse country. Approached along an idyllic country road, the property arrives like a page out of time: four pastoral acres of open meadow, structures that trace their roots to the early 19th century, and the unhurried feeling of a European farmstead - all just an hour from NYC. Bellwether Farm offers something vanishingly rare - the ability to build a primary residence entirely to your own vision, on land already home to a remarkable collection of historic structures.
Architectural plans exist for a modern farmhouse of approx. 3,600 sq ft (plus unfinished lower level), featuring dramatic vaulted ceilings, a full wall of glass opening to sweeping meadow views, and clean proportions that sit comfortably within the landscape. The design envisions four bedrooms and three baths, as reflected in the renderings. A seven-bedroom septic is approved and construction drawings are in hand, providing a clear path toward completion. The property's architect and builder are available to collaborate, or a buyer may engage their own design and team.
What distinguishes Bellwether Farm is a grandfathered multi-structure configuration no longer achievable under current Bedford zoning. The result is a thoughtfully composed compound comprising approx. 3,300 sq ft across three buildings - the Barn, Carriage House, and Milk House - offering rare flexibility for living, hosting, and creative work that a single-structure residence simply cannot.
The Barn, featuring historic details like wavy glass diamond-paned windows and classic barn doors, includes a stylish two-bedroom apartment above and unfinished studio below, suited as a wellness space, creative studio, or lounge. Ready to occupy from day one, the apartment is an ideal base while overseeing construction. The Carriage House, with hand-hewn beams, antique brick floors, and new large-scale commercial glass, awaits final transformation as home office, creative studio, or guest cottage, with living and kitchenette on the main floor and lofted sleeping quarters above. Completion plans for both are approved by the Town of Bedford. The charming Milk House sits quietly apart - perfect for a writer's studio or garden retreat.
Once a thriving working farm, the land remains essentially untouched - open pasture, long meadow views, and historic stone walls that speak to generations of quiet, unhurried life. Mature plantings frame an effortless setting for entertaining, future gardens, and pool placement. A gravel motor court lends a graceful arrival that feels entirely of the place.
Bellwether Farm is a rare chance to build something entirely your own - a country estate with room for guests, and creativity, each in its own dedicated setting, in one of the Hudson Valley's most beautiful and sought-after enclaves.
