when did the construction of the white house begin
White House Construction of the White House began with the laying of the cornerstone on October 13, 1792, although there was no formal ceremony.[15] The main residence, as well as foundations of the house, were built largely by enslaved and free African-American laborers, as well as employed Europeans.[16] Much of the other work on the house was performed by immigrants, many not yet with citizenship. The sandstone walls were erected by Scottish immigrants, employed by Hoban,[17] as were the high-relief rose and garland decorations above the north entrance and the "fish scale" pattern beneath the pediments of the window hoods. The initial construction took place over a period of eight years, at a reported cost of $232,371.83 (equal to $3,279,177 today). Although not yet completed, the White House was ready for occupancy circa November 1, 1800.[18]
President's House (Philadelphia) In 1781, it was purchased, refurbished, and expanded by Robert Morris, who lived here while Superintendent of Finance. Washington lodged here with Morris during the 1787 Constitutional Convention. In 1790, Morris gave up the house for his friend to use as the Executive Mansion, moving to the house next door. President Washington occupied it from November 1790 to March 1797, and President Adams from March 1797 to May 1800. Adams oversaw the transfer of the federal government to the District of Columbia, and first occupied the White House on November 1, 1800.
