Property Description
Beautiful 1910 New Englander in Portsmouth's South End. Set on a corner lot in one of Portsmouth's most sought-after neighborhoods, this 3-bedroom, 2½-bath home is full of charm and character. New owners will feel at home from the moment they walk in and will enjoy the waterviews from most rooms in the house. The first floor opens with a welcoming foyer featuring a large custom closet built from original attic floorboards, leading into a spacious kitchen and living area with soapstone countertops, custom cabinetry crafted from reclaimed barn boards, a custom hood and hardware, and vintage accents throughout. A cozy library with built-in bookcases, a separate dining room with bay window, and a powder room complete the main floor. Upstairs, a light-filled primary suite is joined by two additional bedrooms with generous closet space, a full bathroom, and a built-in office nook. Step outside to the lovely side deck - the perfect spot for morning coffee or dinner with beautiful water views - plus a landscaped yard, patio, bricked driveway and garden shed for your bikes and garden equipment. Water access just down the street to enjoy kayaks and paddleboards and a neighborhood float. Location can't be beat: a short walk to Prescott Park, Strawbery Banke, restaurants, schools, and the library. Everything you need is at your fingertips! Open House: Saturday, 9/19, 12-2 PM
