When Harry Truman became president, he inherited a White House that was structurally unsound and in danger of collapse. Between 1949 and 1952, Truman moved out while the White House was completely gutted, leaving only the outer walls around a shell, as seen here.
The mansion was then rebuilt using concrete and steel beams in place of its original wooden joists.
