Well, I have to say that the only time the White House burned was during the War of 1812 ....
It was gutted by Truman, as he noticed when he walked he could feel the floor sway and groan. The huge timbers that held up the marble flooring and such had been stressed to the maximum and determined to fix it before there was a collapse and more serious damage or losses. Gerald Ford, Senator at the time was instrumental in passing the necessary funding of the refit of the White House but, this time--Steel beams would be used. As the White House was being repaired, he resided at Blair House across the street.
National Geographic years ago, circa Truman's Administration, if memory serves me correctly, followed the progress and the before and after pictures. Measurements, color peeled gently in layers getting down to the bare plaster, as to document the paint colors, removing and numbering, cataloged each piece of marble, every brick, every detail was recorded as to assemble the White House later. Added though was the "Truman Balcony."
I was lucky enough to take a tour of the White House. Back then, in the 1970's-1990's already, though a cop, had to secure it with the U.S. Secret Service before I took the tour, even though they knew me. I went through when it was Christmas.
Just some memories.
