Description

Fantastic two+ bedroom, bath-and-a-half duplex home in the beloved Ansonia Court, with soaring beamed ceilings, gracious rooms, and a lovely private patio. Enter this townhouse-style home through the bright main living level. A gracious living room flows into the stunning open kitchen with separate dining space. There is a beautiful powder room on this floor, and sliding doors leading out to the private patio. Upstairs are two large bedrooms with eleven-foot ceilings, a laundry and mechanical room, and large full bathroom with generous storage. A clever mezzanine level adjoins the second bedroom and is currently used as a play space. Converted to coops in 1982, Ansonia Court was originally part of the 1881 Ansonia Clock Factory and has the huge windows, exposed brick walls and soaring wood beamed ceilings typical of Industrial Era buildings. The hallmark of Ansonia Court is its renowned courtyard, a central oasis with gorgeous flowering trees, benches and lovely water fountain. Stroller and bike storage available just outside your front door. Pet-friendly and a block from Prospect Park, Union Market, Talde and everything that makes Park Slope such an enticing place to call home.
