This room was constructed from 1937-39 as the new Executive Office for Presidents of the Philippines during the administration of Manuel L. Quezon, who was the first to use it. It was also one of the first airconditioned offices in the Philippines, centralized airconditioning being installed under the supervision of Mr. A.D. Williams in 1937. This room was then used in completing paper work and other office duties of the President of the Philippines, while the Presidential Study in Malacañan Palace itself was used for more confidential meetings and matters.
Presidents Laurel, Osmeña, Roxas, Quirino and Magsaysay also used this room as their executive office during their presidencies. President Garcia began using the Presidential Study almost exclusively for official business during his term, a practice followed by Presidents Macapagal and Marcos. However, President Marcos had this room refurbished in 1972 and occasionally used it for official business, until this room became the office of Gen. Fabian Ver. During the term of President Corazon Aquino this room was at first used by the Press Secretary and eventually fell into disuse, until it was restored in 2003.
