The White House requires 570 gallons of paint to cover its outside surface. There are 132 rooms, 35 bathrooms, and 6 levels in the Residence. There are also 412 doors, 147 windows, 28 fireplaces, 8 staircases, and 3 elevators. In 1902, President Theodore Roosevelt began a major renovation of the White House, including the relocation of the president’s offices from the Second Floor of the Residence to the newly constructed temporary Executive Office Building (now known as the West Wing). The Roosevelt renovation was planned and carried out by the famous New York architectural firm McKim, Mead and White. Roosevelt’s successor, President William Howard Taft, had the Oval Office constructed within an enlarged office wing.
