Before Terri Lee could start a cooking demonstration at the Museum of the City of New York last week, she had to demonstrate a few other things.

Her audience was clustered, confused expressions on their faces, in one end of the 325 s/f model apartment in the museum’s third-floor gallery. Some people were standing in the kitchen area itself, inches from Lee’s elbows. In a matter of minutes, however, folding chairs were produced from a rack by the entryway, and a small ottoman unfolded to produce five low stools.

The model apartment is part of MCNY’s “Making Room, an exhibit dedicated to the design of small apartments to accommodate the city’s growing single population.

The exhibit was first suggested by the Citizen’s Housing & Planning Council and not intentionally timed to coincide with the Bloomberg administration’s recent foray into allowing apartments smaller than the current minimum of 400 s/f, according to the exhibit’s curator, Donald Albrecht.
