Welcome to Bellwether Farm, an extraordinary and rare opportunity on the coveted Mt. Holly Road in Katonah, NY. Nestled within the scenic and sought-after landscape of Northern Westchester, this property spans four pastoral acres, offering an unparalleled canvas for creating a legacy estate.
At the core of this property lies a collection of three historic structures: the Barn, Carriage House, and Milk House. Each building, in various stages of meticulous restoration, presents unique opportunities for guest accommodations, creative spaces, or additional living areas.
The Barn seamlessly blends rustic charm with contemporary upgrades. It houses a fully renovated two-bedroom accessory apartment, featuring an updated kitchen, recessed lighting, and a modern full bath. Below, an open studio space awaits transformation, boasting floor-to-ceiling windows and a half bath. Enhancements include new plumbing, electrical systems, Bosch HVAC, Fujitsu mini-splits, and a whole-house generator. Plans for the Barn have been filed and permitted by the Town of Bedford, with a custom-fabricated 26-foot-wide wall of storefront glass ready for installation, ensuring panoramic views and abundant natural light.
The Carriage House, reimagined from its foundation, captures the essence of historic architectural details while integrating a modernist sensibility. With large swaths of commercial glass, ancient hand-hewn beams, and restored antique brick flooring, it is designed for creative living. The structure features cedar shake siding, a standing seam metal roof, all-new electric, and split-level HVAC, with plans filed and permitted by the Town of Bedford.
The quaint Milk House, with its original beadboard interiors and antique brick floors, is ideally suited for conversion into a writer's studio, guest retreat, or garden cottage, all under a new standing-seam metal roof.
The Main House, fully gutted, offers a blank architectural canvas for redevelopment, with architectural plans available for a bespoke modernist home that harmonizes with the bucolic surroundings. The property is ready for development with a seven-bedroom septic system approved by the Board of Health, simplifying the path to creating your dream estate.
Additional amenities include air conditioning, a full and partial basement, a dishwasher, dryer, garage, guest house, private outdoor space, refrigerator, and washer, providing modern comfort within this timeless setting.
Located just one hour north of Manhattan, Bellwether Farm is more than just land and buildings; it is a pastoral sanctuary with the potential to create a multi-structure compound of unparalleled scale and character. Given its current zoning, such an opportunity is irreplaceable.
