Overview of The Chocolate Factory at 275 Park Avenue

The Chocolate Factory, located at 275 Park Avenue in Clinton Hill, Brooklyn, is a historic building originally constructed in 1880. It was designed by the Parfitt Brothers and initially served as a manufacturing facility for the Rockwood & Company Chocolate, which was a major player in the confectionery industry, second only to Hershey's. The building was converted into residential lofts in 2002 and now houses 123 rental apartments. The property was acquired in 2014 by the HK Organization, Brickman, and Jo-Ann Obergfell for $68 million.

The building retains its Romanesque Revival architectural style, featuring classic loft apartments with high ceilings, brick walls, and wood beams. Many units boast 12-foot ceilings, oversized windows, and modern amenities such as stainless steel appliances, in-unit washer/dryers, and wide plank hardwood flooring. The Chocolate Factory offers a range of amenities including a part-time doorman, a fitness center with Peloton bikes, a landscaped courtyard, and a furnished roof deck with views of the Manhattan skyline.

Residents benefit from a vibrant neighborhood with easy access to the Brooklyn Navy Yard, Downtown Brooklyn, and Clinton Hill. The area is rich with cultural and recreational options, including Fort Greene Park and the Pratt Sculpture Park. The building is well-connected with multiple transportation options, including nearby subway lines, bus routes, and a Citi Bike station. On-site parking is available, and the building is pet-friendly.

The Chocolate Factory also features over 25,000 square feet of retail space, including the on-site Café Le Petit Monstre and Brooklyn Creative League Workspace. The building's location offers a unique blend of historic charm and modern convenience, making it an attractive option for those seeking authentic loft living in Brooklyn.
