The 57-year-old United Nations complex will undergo a billion-dollar renovation.

Starting this fall, the Conference, General Assembly and Secretariat buildings will begin a seven-year renovation.

It will be the first time the complex will get a new look since it was built back in the 1950s. The buildings currently violate safety and fire codes and are said to be loaded with asbestos.

The renovation will also make the complex more energy efficient.

Skanska AB — the Swedish construction company that won the bid to overhaul the buildings — also built the open-air stadium for the Jets and the Giants.
