1930 Apartment building stands alone in low rise area...

Unlike a lot of American cities, NYC kept building well after the Stock Market crash and into the 1930's...both places like the Empire State Building and Rockefeller  Center,  and parts of Bellevue Hospital ( remember seeing as a kid the steel skeleton of a hospital building in Detroit that was started right at the beginning of the Depression and just abandoned for lack of funds)..

Also, they kept building apartment buildings, like this one off one a block of East 28th Street with only brownstones and low rise buildings about.

I googled it up and saw the floorplans for the apartments...most of them small rooms, and then all of a sudden one line of apartments with a big living room and three bedrooms. Go figure.

Of course today the place is no doubt co-op and expensive as hell...seems very well maintained...I saw little kids playing outside...how do these families squeeze in to these small apartments?
