Overview of 85 Sixth Avenue

Dating to 1920, 85 Sixth Avenue is a four story, 10 unit pre-war walk up condominium in Park Slope, also known as the Rosehill Condominium. The property was formerly the Carleton Club, a social club associated with architect Mercein Thomas, before its residential conversion.

High ceilings, oversized windows and broad corner exposures recur in the apartments, and several retain exposed brick and wood burning fireplaces. The layout range extends from single level homes to a parlor floor duplex and an open loft organized around a mezzanine sleeping area, operable skylights and 13 foot pressed tin ceilings. The building has shared laundry and common storage.

The corner location at Sixth and St. Marks avenues sits near the meeting point of Park Slope and Prospect Heights, with Prospect Park and Grand Army Plaza about three blocks away. The 2 and 3 trains stop at Bergen Street, while the B and Q stop at Seventh Avenue. Atlantic Terminal, with nine subway lines and Long Island Rail Road service, is also within several blocks.
