Description

Bellwether Farm presents a rare opportunity to step into a storybook property that already lives like a compound today while offering a clear path to create a fully realized bespoke country estate.

Set across four pastoral acres on a quiet country road in the heart of Bedford-Katonah horse country, the property is defined by classic horse fencing, open meadow views, historic stone walls, and a setting that feels removed from time, yet remains just an hour from New York City.

What exists today is a grandfathered multi-structure compound that cannot be recreated under current zoning. Three distinct buildings totaling approximately 3,300 square feet, the Barn, Carriage House, and Milk House, have already undergone significant restoration and improvement, creating immediate usability and long-term flexibility.

The Barn features a fully renovated legal two-bedroom apartment, allowing for immediate occupancy, along with a large lower-level studio space suited for wellness, creative use, or entertaining. The Carriage House blends original hand-hewn beams and antique materials with swathes of commercial glass and is positioned to be finished as a stunning guest residence, office, or studio. The Milk House, smaller in scale and rich in character, offers a quiet retreat set apart from the rest of the property.

The original main house remains on the property, has been fully gutted, and may be renovated or cleared to make way for a new primary residence, offering flexibility depending on a buyer’s vision.

Approved plans are in place for the completion of the Barn and Carriage House, allowing for an immediate and efficient path to fully realizing the existing structures. In addition, architectural plans have been developed for a modern farmhouse of approximately 3,600 square feet, designed with vaulted ceilings, expansive glass, and a layout that captures the surrounding landscape. A seven-bedroom septic system has already been approved. While the new construction plans have not yet been approved, they provide a strong foundation and direction for what can be created.

This duality is what makes Bellwether Farm compelling.

It can be enjoyed immediately as an idyllic country compound with multiple living and working spaces, while also offering the ability to evolve into a larger, fully realized estate with a primary residence that anchors the entire property.

The land itself remains largely untouched for centuries with open pasture, gentle topography, long meadow views, and natural placement for future outdoor living, gardens, or a pool. A gravel motor court framed by the existing structures creates a natural and timeless arrival.

Bellwether Farm is not simply a property to purchase. It is a foundation to build upon. A place to enjoy  today while shaping something far greater over time —a thoughtfully composed legacy estate tailored to your vision and grounded in one of Bedford’s most desirable settings.

Construction drawings, approved renovation plans, and architectural renderings are available upon request.
