In the summer of 2015, Chelsea-based Alfa Development entered into contract to acquire the development site spanning 253-261 Third Avenue (a.k.a 200 East 21st Street), in Gramercy, and now the developer is planning a 20-story, 65-unit mixed-use building. The Real Deal reports the project will measure 104,700 square feet in total and will include 7,200 square feet of ground-floor retail space. The rest of the new building will contain 65 condominium units, which will come in one- to four-bedroom layouts. BKSK Architects will be responsible for the design. Reportedly, the developers filed permits for the project, although they have yet to hit public record. Demolition permits, however, are on file for all of the assemblage’s existing buildings. Four three-story structures are to be demolished at 253-259 Third Avenue, and a five-story, 12-unit tenement building at 200 East 21st Street will be razed.
