Property Description
Perfectly positioned just moments from Prospect Park on one of Park Slope's most coveted blocks, this distinguished circa 1915 limestone townhouse blends the elegance of British Regency architecture with elements of classic Federal design. Spanning 21 feet in width, the home makes an immediate impression with its stately facade, double-columned entry, low granite stoop, and original cast iron fencing, while inside, grand proportions, soaring ceilings, and beautifully preserved details create a timeless atmosphere. Rich in original character and located at a prime address, the home presents a rare opportunity for a full renovation and customization to suit modern moving. The main level features a gracious living room with a sweeping carved staircase, a formal dining room framed by pocket doors, and a spacious kitchen with direct access to a private garden. Upstairs, sunlit bedrooms showcase original features including stained glass, window seats, and decorative mantels, complemented by multiple baths, a gallery landing, and both front and rear staircases for added convenience. Located just off Prospect Park and one block from the best of 7th Avenue's shops and dining, with easy access to transportation and top-rated schools, this is a rare opportunity to own a truly special Park Slope townhouse.
