Built in 1881, the Ansonia Court is a distinguished 70-unit co-op that spans four floors and occupies a full city block. Originally home to the Ansonia Clock Company, the building was designed by the renowned architect Samuel Curtiss Jr. in the striking German Romanesque Revival style. With its central open courtyard and classic architecture, the property exudes both charm and modern convenience. Converted into co-ops in 1982 and now known as Ansonia Court, the lofts retain their original character, featuring exposed brick and timber, soaring ceilings, and oversized windows.
Nestled in the heart of the vibrant South Slope, this home is just one block from the sprawling beauty of Prospect Park and conveniently located near all the area's best dining, shopping, and transportation options. With everything you need just in close proximity along 7th Avenue, this location offers unbeatable convenience and access to everything you need.
