UNICEF is the third building of the United Nations Plaza Development. Located on 44th Street across from the U.N. Plaza I and II, this fifteen-story building houses the world headquarters of UNICEF.

The top two floors contain apartments that are made available to the UN staff, and this residential use is expressed by the sloping green-colored mansard roof and dormer windows. The ground floor, in addition to housing the lobbies for the apartments and office building, contains employee dining rooms and a large exhibition space that will open out onto a public park. A twenty-foot high colonnade knits the park and the base of the building together and continues around the inside walls of the park.

The building, which uses the same green reflecting glass as the U.N. Plaza I and II has its structure clad with bands of pink and green granite. Both the colonnade columns and the cladding of the main structure are treated as cut-out elements, using 3 cm and 5 cm thick granite slabs cut in a such a way as to give a much greater sense of depth.
