The 1001 5th Avenue involved subsequently two architectural firms to bring the building to its present appearance of early Post-modernist adaptation in 1979.
After the Landmarks Preservation Committee rejected the original, flat-top design, a tapering, fake mansard roof -- merely a wall facing the street -- was added, getting its influence from the Beaux-Arts neighbour.
The building incorporates 76 co-op apartments, many combined from smaller units.
The base of the 22-storey building follows the rusticated austerity of the neighbouring palazzo, with the upper facade split by a series of glass-walled vertical shafts and protruding horizontal ornaments "extending" from the building next door.
The facade facing Fifth Avenue is clad in limestone, while the other facades are of buff brick.
