645 Carlton Avenue is a 1910 pre-war cooperative in a 24 foot wide limestone townhouse at the end of a Prospect Heights row. Its most distinctive residence is a parlor and garden duplex, with living space on the parlor level and bedrooms arranged below around a 35 foot wide landscaped garden.
The four story, four unit building retains a strong collection of pre-war details, including ornate woodwork, plaster moldings, patterned hardwood floors, and west facing bay windows. Several apartments have east, south, and west exposures, while fireplaces and flexible room arrangements recur among the homes. The building also has an intercom, common basement storage, and bike storage for each apartment.
Set just off Flatbush Avenue and close to Vanderbilt Avenue, the co-op is surrounded by Prospect Heights restaurants, shops, and neighborhood institutions. Prospect Park, the Brooklyn Botanic Garden, Brooklyn Museum, Brooklyn Public Library, Grand Army Plaza Greenmarket, Barclays Center, and Atlantic Terminal are all close by. The building is pet friendly, and its common areas have recently been renovated.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
