Built in the 1800s and once home to the community's only doctor, this historic colonial blends timeless character and craftsmanship with modern updates. The main level features a spacious kitchen, a formal dining room with a fireplace, and an inviting living room with a second fireplace. A brand-new full bathroom and laundry room with pantry on the main floor adds convenience, while the mudroom entrance provides everyday functionality. The sunroom, lined with windows, offers a bright and peaceful retreat overlooking the property. Upstairs, you'll find three generously sized bedrooms and a second full bathroom, all accessed by two separate staircases on the first floor. An additional staircase leads to a third-level unfinished attic, already framed and ready for expansion for future bedrooms, office space or a creative studio. With newer windows, central A/C installed, new siding, fresh paint, and refreshed with hardwood flooring throughout, this home feels beautifully renewed while preserving its historic charm. Set on nearly an acre, the property features a wraparound driveway, patio, fire pit area, garden area, and a large storage shed creating a functional outdoor lifestyle. Located just minutes from Route 80 for easy commuting, yet nestled in the peaceful countryside of rural Warren County, this remarkable home offers history and beauty all in one extraordinary setting.
