The current Administration Building or Mabini Hall on Ycaza Street is the large structure to the left upon entering Gate 4. It began as the Budget Building upon the creation of the Budget Commission (now the Department of Budget and Management) in 1936. After World War II, it temporarily housed the Supreme Court, as the Ayuntamiento building was destroyed during the Battle for Manila in February 1945. After the war, it was later expanded with wings and top floors added. It houses the office of the executive secretary, some units of the Department of Budget and Management, and offices of presidential assistants and advisers. Some offices in this building, particularly those of the Office of Media Affairs, were invaded by an unruly mob on the evening of February 25, 1986, during the storming of Malacañang that capped the People Power Revolution. After it was gutted in a fire in 1992, plans to demolish it and build a high-rise building in its place were completely dropped due to budgetary constraints. President Fidel V. Ramos supervised its reconstruction into a spartan but well-ventilated and lit office complex, and renamed it Mabini Hall, after Apolinario Mabini."Mabini Hall". Presidential Museum & Library.
