Principal story plan for the White House, the official residence and principal workplace of the President of the United States, by Benjamin Henry Latrobe, 1807. Construction began with the laying of the cornerstone on October 13, 1792. Originally designed by James Hoban to be five times larger than the house that was eventually built, it was first occupied by John Adams. His successor Thomas Jefferson, in conjunction with Latrobe, expanded the White House to include the East and West Colonnades, which link the residence with the East and West Wings.Restoration: Lise Broer
