Historic clock factory turned loft-style co-op in South Slope

Ansonia Court, located at 420 12th Street in Brooklyn's South Slope neighborhood, is a coveted address that seamlessly blends industrial heritage with modern living. Originally constructed in 1881 as a clock factory, this four-story brick building was designed by architect Samuel Curtiss Jr. in the German Romanesque Revival style. The structure underwent a transformation into a residential co-op, now housing 70 unique loft-style units. Ansonia Court's distinctive character is defined by its European-inspired interior courtyard, a lush oasis that serves as the heart of the community.

Spacious lofts with original industrial features

Ansonia Court offers a range of floor plans, from cozy one-bedroom units to expansive three-bedroom duplexes. The smallest units start at approximately 920 square feet, while the largest span up to 1,500 square feet. One-bedroom apartments, around 900 square feet, typically rent for about $4,000 per month. Two-bedroom units vary from 1,050 to 1,480 square feet, featuring 1.5 to 2 bathrooms, with sale prices ranging from $1,785,000 to $1,885,000. The three-bedroom layouts, approximately 1,500 square feet, boast 2.5 bathrooms and are ideal for families or those seeking extra space. These loft-style homes showcase the building's industrial past with exposed brick walls, original wood beams, and soaring ceilings up to 13 feet high. Many units feature oversized factory windows that flood the spaces with natural light. Renovated kitchens often include chef-grade appliances, custom cabinetry, and stone countertops. Some apartments offer private outdoor spaces such as balconies or garden patios, perfect for al fresco dining or urban gardening. In-unit washer/dryers, hardwood floors, and custom storage solutions are common features throughout. The building's unique layout allows for creative floor plans, including duplex options with separate living and sleeping areas.
