About This Property

A RARE OPPORTUNITY TO CREATE A PARK SLOPE HOMEResidence 1A is currently configured and legally designated as a medical office. The co-op permits the residential conversion, giving a buyer the opportunity to work with an architect and contractor to create a home tailored to their needs. Alternate floor plans illustrate two possible two-bedrooms layout. The bathroom has been virtually staged with a bathtub.What makes the opportunity particularly compelling is what already exists: a corner position, southern exposure, oversized casement windows and excellent natural light. The first floor is elevated above street level, while a dedicated private entrance from the street creates a true sense of arrival and provides a practical transition space for bikes, strollers and everyday storage.The existing footprint lends itself to a generously proportioned two-bedroom home with substantial living and dining space. Deep closets throughout provide unusually good storage, and the current configuration gives a buyer flexibility to rethink the layout rather than renovate around someone else's choices.Financing options are available and we can connect interested purchasers with a lender experienced in renovation loans for co-op properties.Built in 1927 and designed by Sugarman & Berger, the architects behind One Fifth Avenue, The President is a full-service prewar co-op with a 24-hour doorman, live-in superintendent, laundry room and bike storage. The building is pet-friendly and retains many of its original prewar details.The location is quintessential North Park Slope. Prospect Park and Grand Army Plaza are just blocks away, along with the Saturday Greenmarket, neighborhood restaurants, shops and cafés. Transportation is exceptionally convenient, with the 2/3 trains at Grand Army Plaza and the B/Q at 7th Avenue nearby.The address is zoned for P.S. 321.This is not a move-in-ready apartment unless you are a physician using as a medical office. It is the opportunity to create one, in a full-service prewar building just one block from Prospect Park.Buyer should independently verify all plans, approvals, conversion requirements and permitted use with their architect, attorney and other appropriate professionals.
