...A stylish, split-level CONVERTIBLE three-bedroom, two-bathroom home with private outdoor space awaits in the vibrant center of Prospect Heights.

Beautifully maintained and filled with character, this residence offers generous living space, excellent storage, and a warm, inviting atmosphere. (Some photos have been virtually staged to help illustrate the home’s potential.)

The main level features tall ceilings, well-kept hardwood floors, and a charming wood-burning fireplace in the large living room. The open kitchen is outfitted with sleek cabinetry, stone countertops, and stainless steel appliances, including a gas range and dishwasher — perfect for both everyday living and entertaining.

Off the entry, you’ll find a full guest bathroom, a laundry closet with an in-unit washer and dryer, and extra storage. The primary bedroom enjoys peaceful treetop views, floor-to-ceiling closets, and a private en suite bathroom. A bright second bedroom with built-in storage and a roomy closet sits on the opposite side of the home for added privacy.

Upstairs, a versatile loft space works beautifully as a den, media room, or third bedroom and opens directly to your own 100-square-foot private rooftop retreat — an ideal spot for morning coffee or evening relaxation.

521 Dean Street is a well-maintained, self-managed cooperative set in a classic 1930s brick and brownstone building. Perfectly located on a quiet, tree-lined street just minutes from Atlantic Terminal, Barclays Center, BAM, Prospect Park, and the shops and restaurants of Vanderbilt Avenue. Multiple subway lines (2/3, B/D, N/Q/R, 4/5) and the LIRR put the entire city within easy reach.
