The Secretary-General requested, and the General Assembly approved, two construction projects at UNON to the amount of nearly USD 340 million, the largest investment the UN Secretariat has undertaken in Africa since its inception, besides peacekeeping. These are:
- Increasing the number of meeting rooms from 14 to 30 (including replacement and refurbishing of some existing buildings).
- Construction of an Assembly Hall with capacity for 1600 participants. The UN Secretariat currently has two Assembly Halls of this scale, one in Geneva inaugurated in 1937 by the League of Nations and one in New York completed in 1952.
