The history of the White House as a structure is fascinating.
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.
When the Trumans moved into the executive mansion in 1945, they found it badly in need of repair after twelve years of neglect during the Depression and war. In 1946, Congress authorized $780,000 ($11 million 2018 dollars) for repairs. The mansion's heaving floors and mysterious sounds had been known by staff and First Families for many years.[2] For the first two years of his presidency, according to White House photographer Abbie Rowe, President Truman heard "ghosts" roaming the halls of the Second Floor residence.[3]:535[4] Government agencies had expressed concern about the condition of the building, including a 1941 report from the Army Corps of Engineers warning of failing wood structure, crumbling masonry, and major fire hazards. The report was dismissed by President Roosevelt.[5]
In early 1946, during a formal reception in the Blue Room, the First Lady noticed the very large crystal chandelier overhead swaying and its crystals tinkling. The floor of the Oval Study above moved noticeably when walked on, and a valet was then attending the president while he was taking a bath. (Truman described a potential scenario of him in his bathtub falling through the floor into the midst of a Daughters of the American Revolution tea "wearing nothing more than his reading glasses.").[6] In early 1947, a "stretching" chandelier in the East Room and another swaying in the Oval Study caused further alarm.[7][8] โFloors no longer merely creaked; they swayed."
The building was a "gut job". The interior framing is now structural steel. But making the building safe for occupancy was just half the task. Jacqueline Kennedy took on phase two:

"In September 1961, Congress passed a law making the White House a museum. This meant any donated antiques and art became the property of the White House and was placed in the care of the Smithsonian when not in use. Donors, therefore, knew that future presidents wouldn't be taking any pieces of history with them when their time in the White House came to a close. The legislation also reassured Kennedy that her restoration work couldn't be completely undone by a future first family."
Everybody remember when the Clintons tried to steal china and furniture on their way out?
