As of 2014, there are 132 rooms across six levels in the White House, along with eight staircases, six elevators, 35 bathrooms, 28 fireplaces, 412 doors and 147 windows. The White House has undergone several remodeling projects and additions throughout its history, which began in 1791 when President George Washington himself selected the site for the president of the United States' home. Though he selected the site, Washington never lived in the White House; John Adams and his wife Abigail Adams took residence in the first official version of the executive mansion in 1800, when the house was still unfinished.
