A wonderful opportunity to own "Portsmouth" a significant and much admired gem of a house in Bronxville's cherished Lawrence Park. Designed by prominent architect William Bates in 1903, its design may have been influenced by that of the historic Longfellow House in Cambridge Mass. Beautifully landscaped on a gentle knoll, it is stately and elegant on the outside and well designed and comfortable on the inside. Thoughtfully restored by the current owners and architect Susan Alisberg, the home encompasses 5,400 sf with 7 bedrooms and 4 baths. A stunning center hall, high ceilings, deep millwork, multiple windows and fireplaces, an open porch on either side of the living room and dining room all define its allure.The main rooms are gracious and impressive. The super functioning and well equipped kitchen with center isle and butler's pantry is adjoined by a spacious family room and custom mud room. A perfect home office and a powder room complete the first floor. A beautiful, open period staircase leads to a spacious second and third floor with lovely, airy bedrooms and modern baths. An additional, new 1,830 sf lower level is a fabulous attraction with a playroom, gym, wine room and more. A long driveway, easily accommodating multiple cars, leads to the house and two car garage. We all know location is everything and this house has the best. It is surrounded by equally beautiful homes, is a delightful walk to Bronxville's highly ranked schools, village center and train and enjoy the quiet enchantment and appeal of the Hilltop.
