4 East 66th Street/845 Fifth Avenue

A conservative but well-proportioned building, 4 East 66^th Street, also known as 845 Fifth Avenue, was designed by J.E.R. Carpenter in 1920.  Carpenter was at the front of new zoning changes for this stretch of Fifth Avenue, bringing a lawsuit against the city that resulted in the widespread development of the Upper East Side with apartment houses by himself and his peers.

The original interiors of 4 East 66th Street were highly ornate, in contrast to the stark exterior.

4 East 66^th Street was converted to a co-op in 1949.
