This exceptional home at 870 President Street is one of only 19 of 4,500 Park Slope townhomes that measure 30 feet wide or more. The home, asking $7,995,000, sits on a prime north Slope lot, a block from Prospect Park. Behind a grand Romanesque Revival facade, the two-family townhouse has resisted the familiar contemporary aesthetic, keeping its intricate interior architecture preserved along with plenty of 19th-century charm.

Built in 1888 by Charles F. Burckett, the townhouse was first occupied by silk manufacturer Charles C. Knowlton and remained in the family for 40 years. Its facade is recognizable by an arched entrance and three-story bay of rough-cut stone and checkerboard masonry.

Enter the parlor floor through double doors into a gallery foyer that provides the first introduction to a wealth of graceful details that enhance its historic frame. Within, you’ll find encaustic tile floors with mosaic borders, Lincrusta wall coverings, and a fireplace, anchored by a winding center staircase with hand-carved banisters. Beneath 11-foot ceilings, two formal parlors showcase delicate woodwork, carved mantels, and wainscoting.

Past a formal dining room in a sun-filled rear extension is the home’s main kitchen with windows on three sides. The kitchen opens onto a deck leading to the garden below. There is a full bath on this floor as well.

Up a skylit staircase is a large living room, two bedrooms, and a full bath. A second eat-in kitchen opens onto a roof terrace that holds an enchanting pergola with a treehouse vibe.

On the home’s top floor are three more bedrooms and a dedicated office suite. This flexible space is served by a full bath and windowed laundry room.

The home’s lowest level is a windowed cellar with plenty of storage space and lots of potential. With ceilings nearly nine feet high, this floor would be perfect for a gym, workshop, or play space.
