Recognized as Maison Winchester in Cowansville's heritage documentation, the residence preserves the symmetry, proportions and restrained detailing of its nineteenth century origins while reflecting nearly two centuries of evolution.

Based on the measured floor plan, the home offers approximately 4,531 sq. ft. of above-grade living area. Its configuration provides an uncommon variety of formal and informal spaces, including an expansive living room, large dining room, multiple family rooms, six bedrooms, three full bathrooms and a powder room. A main floor bedroom adds flexibility for guests, an office or extended stays, while two staircases connect the main and upper levels.

The major addition undertaken by the current owners went through the City of Cowansville approval process and introduced a generous contemporary kitchen and adjoining everyday living spaces. Anchored by an approximately 14.5 foot island, the kitchen features heated flooring, abundant cabinetry and substantial preparation space. A large screened veranda extends the living environment toward the grounds and creates a natural setting for dining and relaxation. Two of the home's main bathrooms have also been fully renovated with heated floors.

Outside, mature landscaping surrounds an in ground concrete pool, extensive gardens, a large Cumaru hardwood deck and a six person hot tub, creating distinct areas for entertaining and quiet enjoyment. The former stable, part of the property's history, has been converted to a three car garage while retaining architectural details recalling its original equestrian use. A circular driveway and the home's setback from rue Principale reinforce the estate setting and sense of privacy.

The complete property comprises five contiguous cadastral lots totaling 23,550.2 m², approximately 5.82 acres. The house and immediate estate occupy three lots totaling 9,483.2 m², approximately 2.34 acres. Two additional contiguous lots totaling 14,067 m², approximately 3.48 acres, are carried under a separate municipal assessment account and may be sold separately from the residence. This configuration provides long term flexibility while preserving the scale and privacy of the complete estate. Any future use remains subject to applicable municipal regulations and approvals.

Municipal water and sewer, a 400 amp electrical supply and bi energy heating add practical infrastructure for a residence of this scale.

Located within Cowansville rather than in an isolated rural setting, Winchester House combines substantial grounds and privacy with convenient access to everyday services, Brome Missisquoi Perkins Hospital and the broader Eastern Townships lifestyle, including Bromont, Lac Brome, Sutton and the surrounding recreational region.

Winchester House also appears briefly in The Human Stain, starring Anthony Hopkins and Nicole Kidman, another chapter in the story of a residence that has been part of the local landscape since circa 1840.
