The cornerstone of the White House was laid in 1791 on a site along the Potomac River, selected by George Washington. The neoclassical mansion was designed by Irish-born architect James Hoban and originally built by enslaved laborers from 1792 to 1800. The first president to live in the White House was John Adams, who moved in with first lady Abigail Adams in 1800, even though construction hadn’t quite finished. (There was a gaping hole, for example, where the grand staircase would be.)
Lime-based whitewash was applied in 1798 to protect the sandstone exterior from freezing and cracking, giving the building its signature hue. Originally called the President’s House or Executive Mansion, newspapers started referring to the stately home at 1600 Pennsylvania Avenue as the White House as early as 1810. President Theodore Roosevelt officially changed the residence’s name to the White House in 1901.
In its 200-plus-year history, the White House has gone through several major renovations. Here are some of the biggest changes and their historical significance.
