Introducing the newly reimagined 18 Hereford Street, an exceptional Back Bay single-family residence offering remarkable scale, soaring ceilings, oversized windows, and abundant natural light. Built circa 1871 for builder and contractor George Martin Gibson, this distinguished home is one of four contiguous residences he developed on the block. (Historical information from the Back Bay Houses website). A gracious foyer welcomes you inside, opening to an elegant living room and an adjoining formal dining room. A dramatic curved staircase leads to the second floor, the heart of daily living, with a warm den, inviting dining space, a kitchen with stainless-steel appliances and granite countertops, and a full bath. The third floor offers three generously proportioned bedrooms and a full bath. Three additional bedrooms, another full bath, and a laundry room occupy the fourth floor. Either upper level offers excellent flexibility for creating a spacious, customized primary suite. Fully renovated in 2023, the garden level opens directly to a charming brick patio and features a kitchenette, full bath, and versatile bedroom-ideal for guests, an au pair, a home gym, or a family room. Thoughtful updates include electrical, heating, and HVAC improvements. Rental parking is available nearby. Ideally situated in Back Bay, 18 Hereford Street is moments from the neighborhood's shopping, dining, green space, and cultural amenities.
