Tin ceilings aren’t uncommon in prewar New York apartments, but they’re usually painted over white. This prewar garden duplex, at the Gramercy Park cooperative 224 East 18th Street, is featuring bold, silver ceilings on its main floor–an original design element of the 1920s townhouse. A more recent renovation transformed the apartment from a two bedroom into a one bedroom with a den/media room downstairs. There’s also access to a private backyard garden. The ask comes in at $1.55 million.
