<P> The White House Reconstruction , also known as the Truman Reconstruction , was a comprehensive dismantling and rebuilding of the interior of the White House between 1949 - 1952 . A century - and - a-half of wartime destruction and rebuilding , hurried renovations , additions of new services , technologies , an added Third Floor , and inadequate foundations brought the Executive Residence portion of the White House Complex to near - imminent collapse . In 1948 architectural and engineering investigations deemed it unsafe for occupancy and President Harry S. Truman , his family , and the entire residence staff were relocated across the street . For over three years the White House was gutted , expanded , and rebuilt . The scope , costs , and historical authenticity of the work were controversial , with the reconstruction being called both structurally essential , and a disaster . </P>
