Because of crowding within the executive mansion itself, President Theodore Roosevelt had all work offices moved to the newly constructed West Wing in 1901. Eight years later, President William Howard Taft expanded the West Wing and created the first Oval Office. This was eventually moved as the section was expanded. The third-floor attic was changed into living quarters in 1927. A newly built East Wing was used as a reception area for social events. Jefferson's colonnades connected the new wings. East Wing changes were completed in 1946. These changes made more office space. By 1948, the house's load-bearing exterior walls and internal wood beams were found to be close to failure. Under Harry S. Truman, the interior rooms were completely taken apart and a new internal load-bearing steel frame was built inside the walls. Once this work was done, the interior rooms were rebuilt.
