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.

A Once-in-a-Generation Estate Opportunity on Mt. Holly Road, Katonah-Lewisboro School District. Set on four pastoral acres in one of Northern Westchester’s most iconic and sought-after addresses, Bellwether Farm presents an exceptionally rare development opportunity: the chance to establish a legacy estate on storied Mt. Holly Road. Defined by rolling meadows, ancient stone walls, & classic white horse fencing, the property evokes the spirit of a bygone era — a return to the quiet elegance of 19th-century farm life. Once a thriving working farm, the land remains a pristine tableau of open, level fields and enduring natural beauty. At the heart of the property stands a curated collection of three historic structures — the Barn, Carriage House, and Milk House — each in various stages of thoughtful restoration by designer Tom Givone and ideal for guest accommodations, creative spaces, or auxiliary living. The Main House has been fully gutted, providing a blank architectural canvas for redevelopment. Together, they offer a rare convergence of heritage and possibility — the opportunity to honor the past while creating a bespoke, multi-structure country estate infused with modern luxury. The Barn, a striking marriage of rustic charm and contemporary upgrades, retains historic details such as wavy glass diamond-paned windows and oversized barn doors. A fully renovated two-bedroom accessory apartment includes an updated kitchen, recessed lighting, and a new full bath. Below, a flexible open studio space with floor-to-ceiling windows and a half bath awaits final transformation. Additional upgrades include new plumbing and electric, Bosch HVAC, Fujitsu mini-splits, and a whole-house generator. A dramatic 26-foot-wide wall of storefront glass has been custom-fabricated to maximize morning light and panoramic views, and is ready for installation at the new owner's discretion. All plans for the Barn have been filed with and permitted by the Town of Bedford. The Carriage House, reimagined from the foundation up, blends original architectural details with modernist sensibility. Large swaths of commercial glass flood the open plan interiors with natural light and create a dramatic contrast with ancient hand-hewn beams, restored antique brick flooring, and original wavy glass windows – ideal for creative living. Cedar shake siding, a standing seam metal roof, new footers, all-new electric, and split-level HVAC provide long-term functionality. All Carriage House plans have been filed with and permitted by the Town of Bedford. The charming and compact Milk House features original beadboard interiors, antique brick floors, and wavy glass windows, all set beneath a new standing-seam metal roof. It is perfectly suited for conversion into a writer’s studio, guest retreat, or garden cottage. The Main House presents an exceptional opportunity to create a custom dream residence from the ground up. For those seeking inspiration, architectural plans for a bespoke modernist home seamlessly integrating stunning architecture into the bucolic landscape are available for consideration. The land has been cleared and improved, with a seven-bedroom septic system approved by the Board of Health, offering a streamlined path to development. Just one hour north of Manhattan, Bellwether Farm is more than land and buildings; it is a pastoral sanctuary, a generational property of rare provenance and potential. In a region celebrated for its distinguished country homes, the opportunity to create a multi-structure compound of this scale and character on Mt. Holly’s historic dirt road is truly vanishing. Current zoning would no longer allow such a development, making this an irreplaceable offering.
