The exterior walls rest on new concrete underpinnings, which allow earth-moving equipment to dig a new basement.
context_page_description: The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800. The term "White House" is often used as a metonym for the president and his advisers.
  The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800 using Aquia Creek sandstone painted white. When Thomas Jefferson moved into the house in 1801, he added low colonnades on each wing that concealed stables and storage. In 1814, during the War of 1812, the mansion was set ablaze by the British Army in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed Executive Residence in October 1817. Exterior construction continued with the addition of the semi-circular South portico in 1824 and the North portico in 1829.
context_section_description: Decades of poor maintenance, the construction of a fourth story attic during the Coolidge administration, and the addition of a second-floor balcony over the south portico for Harry S. Truman took a great toll on the brick and sandstone structure built around a timber frame. By 1948, the house was declared to be in imminent danger of collapse, forcing President Truman to commission a reconstruction and to live across the street at Blair House from 1949 to 1951. The work, done by the firm of Philadelphia contractor John McShain, required the complete dismantling of the interior spaces, construction of a new load-bearing internal steel frame and the reconstruction of the original rooms within the new structure. The total cost of the renovations was about $5.7 million ($56 million in 2019). Some modifications to the floor plan were made, the largest being the repositioning of the grand staircase to open into the Entrance Hall, rather than the Cross Hall. Central air conditioning was added, as well as two additional sub-basements providing space for workrooms, storage, and a bomb shelter. The Trumans moved back into the White House on March 27, 1952. While the house's structure was kept intact by the Truman reconstruction, much of the new interior finishes were generic, and of little historic value. Much of the original plasterwork, some dating back to the 1814–1816 rebuilding, was too damaged to reinstall, as was the original robust Beaux Arts paneling in the East Room. President Truman had the original timber frame sawn into paneling; the walls of the Vermeil Room, Library, China Room, and Map Room on the ground floor of the main residence were paneled in wood from the timbers.
