About this home

Classic center hall antique colonial, originally constructed in 1794, has been beautifully renovated, tastefully expanded, and well maintained and is now poised to be passed on to the next fortunate owner. Among the many striking features include exposed hand hewed oak beams, wide plank pine flooring, and a soaring two-story stone fireplace. The recently renovated kitchen with custom cabinetry, granite countertops, and high-end appliances opens onto a large family room with a second fireplace. The spacious primary bedroom boasts cathedral ceilings, a large walk-in closet and spa-like bath. The home's expansion was designed by Jay Haverson of Haverson Architecture & Design and accomplished using high-end building materials such as Marvin windows and custom designed antique doors. Situated on a unique and oversized half-acre plus lot makes this convenient close-to-town home feel private and secluded. The oversized lot, coupled with the benefit of town sewer services, also offers up to 2000 sq. ft. of further expansion possibilities. Truly an amazing opportunity in today's real estate market.
