Description
Welcome home to your sunny, 20 ft wide historic landmarked, classic Brooklyn brownstone on an extra wide, tree-lined street, with direct access to Prospect Park. This 1901 Neo-Grecian townhouse, designed by architects Baker & Lincoln, has Queen Anne elements spread across four stories plus a full basement. Delight in this beautiful home with classic, pre-war charm as shown in the: soaring ceilings, custom built-ins, decorative fireplaces, mantles, beadboard wainscoting, crown moldings, inlaid hardwoods, bay windows, pocket doors, ornate banisters, railings and so much more! Currently used as a single-family, this home has a certificate of occupancy as a three-family, allowing for flexible use. This grand townhouse will be delivered vacant and sold "as-is". It presents as an extraordinary opportunity to create your own vision as a single-family mansion or a grand scale owner's unit with a full basement and rental income. The two upstairs units each have two bedrooms, a living and dining room, with one kitchen and bath. The downstairs duplex is generously comprised of three bedrooms and one-and-a-half baths, with private access to the lovely, large back garden and a full basement. Additional creature comforts include central a/c (on the 1st and 2nd floors), a side-by-side washer/dryer and excellent storage throughout. Come experience this pre-war masterpiece, and discover home on this double-wide street above 7th Ave in prime Park Slope, Brooklyn. Situated on a tree lined street and zoned for PS 39, this historic brownstone is less than five minutes away from many award-winning restaurants, and is only a stone's throw away from Prospect Park, where you can enjoy an invigorating run or enjoyable picnic, or a movie at the Nitehawk theatre. Finally, this sizable brownstone is less than a block away from the new, state-of-the-art, handicap-accessible F/G train stop, allowing for easy transportation into Manhattan or elsewhere.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
