The Ansonia Court is a four-story, red-brick building at 420 12th Street in the Park Slope section of Brooklyn.  It once housed the Ansonia Clock company. 

The building has 70 cooperative apartments. 

The building is also known as 393-407 13th Street and 392-405 7th Avenue and it is about three blocks form the 7th Avenue subway station and about two blocks from Prospect Park. 

The 1881 building was converted to a cooperative by the early 1982 and is notable for its very large, impressive and nice courtyard and brick wall interiors.  

Hurley & Farinella was the architect for the conversion and Zion & Breen were the landscape architects for its one-third-acre interior courtyard.
