In 1891, First Lady Caroline Harrison proposed major extensions to the White House, including a National Wing on the east for a historical art gallery, and a wing on the west for official functions. A plan was devised by Colonel Theodore A. Bingham that reflected the Harrison proposal. These plans were ultimately rejected. However, in 1902, Theodore Roosevelt hired McKim, Mead & White to carry out expansions and renovations in a neoclassical style suited to the building's architecture, removing the Tiffany screen and all Victorian additions. Charles McKim himself designed and managed the project, which gave more living space to the president's large family by removing a staircase in the West Hall and moving executive office staff from the second floor of the residence into the new West Wing. President William Howard Taft enlisted the help of architect Nathan C. Wyeth to add additional space to the West Wing, which included the addition of the Oval Office. In 1925, Congress enacted legislation allowing the White House to accept gifts of furniture and art for the first time. The West Wing was damaged by fire on Christmas Eve 1929; Herbert Hoover and his aides moved back into it on April 14, 1930. In the 1930s, a second story was added, as well as a larger basement for White House staff, and President Franklin Roosevelt had the Oval Office moved to its present location: adjacent to the Rose Garden. Truman reconstruction 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 $5.7million ($ million in ). 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
