303 East 57th Street 15KNew York, NY 10022

The living room runs twenty-two feet, and the windows look out to the Queensboro Bridge and the skyline behind it.

At about 750 square feet, 15K has the proportions of a one-bedroom without the walls. A dining foyer of 9'7" by 13'9" opens off the living room room for a full table, or for a bed set behind a screen. The kitchen is its own room rather than a line of appliances along a wall. Closets flank the entry hall, the kind of storage you notice a month in rather than on the walkthrough.

When it opened in 1967, the Excelsior ranked among the tallest residential buildings in New York City. Philip Birnbaum's assertive midcentury design gave the tower its signature notched massing for added corner exposures, and its office-bearing lower floors made it an early mixed-use experiment. It remains a commanding presence at the junction of Midtown East and Sutton Place and a long-standing standout among the city's full-service co-ops.
