<P> The toilet and laundry room west of the kitchen became general - use work areas by 1809, and a pantry, small kitchen, and cook's office by 1825 . By 1946, these had become general workrooms, with a narrow, winding staircase inserted into the room closest to the former kitchen . The 1952 renovation turned the winding staircase into a steep, straight stairs and added an elevator in this space . As of 2010, a pantry - sized refrigerator also occupied a portion of this space . </P> <P> The oval space beneath what is now the Blue Room was originally a Servants' Hall, but was turned into a furnace room in 1837 . During the White House's 1902 renovation, the room was turned into a sitting room . President Franklin D. Roosevelt used it for his "fireside chat" radio broadcasts in the 1930s . Rebuilt (along with the rest of the gutted White House) during the 1948 - to - 1952 renovation, the room became the Diplomatic Reception Room . It was only sparsely furnished until First Lady Mamie Eisenhower received a large donation of museum - quality antique furniture from the National Society of Interior Designers in 1960 . Except for decorative updating, it remains unchanged as of 2010 . </P> <P> West of the Servants' Hall, the Ground Floor originally contained a small bedroom and, in the two westernmost rooms, a Steward's Office . The smaller, westernmost of the two rooms in the Steward's Office became the White House vault . By 1825, the Housekeeper's Office had moved into the easternmost room of the Steward's Office . The Steward's Office and vault became general workrooms by 1946, but the 1902 renovation had turned the Housekeeper's Office into a ladies' powder room . Less than a decade later, President Woodrow Wilson turned it into a billiards room . At the outbreak of World War II in December 1939, President Franklin Roosevelt removed the billiards table and turned the room into a place where he could keep track of the war's progress on a wide range of maps and store top - secret communications with world leaders . The Map Room (as it was now called) was heavily guarded, as highly secret U.S. and allied military information was constantly updated on the maps kept in this room . In the early 1960s, the Map Room was transformed into a ladies' powder room again by Jacqueline Kennedy, and portraits of First Ladies were hung there . The Map Room continued to retain its name, but in 1970 was decorated in the Chippendale style and turned into a reception room . It retained its name and function as of 2010 . A small medical clinic and the office of the White House physician occupy the three rooms to the west of the Map Room as of 2010 . </P> <P> East of the original Servants' Hall was the Housekeeper's Office, and then a room for general work . The Housekeeper's Office was turned into general workspace in 1809, while the bedroom became a general - use servants' room . All rooms east of the oval Servant's Hall were turned into staff bedrooms by 1825 (with the Housekeeper's Office taking up a portion of the Steward's Office). In 1837, President Martin Van Buren made the bedroom that would become the China Room into quarters for a stoker, whose job was to keep the White House furnace fueled 24 hours a day, seven days a week (with summers off). First Lady Edith Wilson turned this room into the China Room in 1917 to display the Executive Residence's growing collection of White House china . Just east of the China Room, the 1902 renovation turned the staff bedroom into a sitting room known as the Social Room . It was briefly renamed the Billiard Room after the 1952 restoration, but became the Vermeil Room in 1957 after mining heiress Margaret Thompson Biddle bequeathed 1,575 pieces of vermeil silverware to the White House . It remained little changed as of 2010 . </P>
