The official home for the U.S. president was designed by Irish-born architect James Hoban in the 1790s. Rebuilt after a British attack in 1814, the “President’s House” evolved with the personal touches of its residents, and accommodated such technological changes as the installation of electricity. The building underwent major structural changes in the early 1900s under Teddy Roosevelt, who also officially established the “White House” moniker, and again under Harry Truman after WWII. Counting the Oval Office and the Rose Garden among its famous features, it remains the only private residence of a head of state open free of charge to the public.
Not long after the inauguration of President George Wasington in 1789, plans to build an official President’s House in a federal district along the Potomac River took shape. A contest to find a builder produced a winning design from Irish-born architect James Hoban, who modeled his building after an Anglo-Irish villa in Dublin called the Leinster House.
The cornerstone was laid on October 13, 1792, and over the next eight years a construction team comprised of both enslaved and freed African Americans and European immigrants built the Aquia Creek sandstone structure. It was coated with lime-based whitewash in 1798, producing a color that gave rise to its famous nickname. Built at a cost of $232,372, the two-story house was not quite completed when John Adams and Abigail Adams became the first residents on November 1, 1800.
Thomas Jefferson added his own personal touches upon moving in a few months later, installing two water closets and working with architect Benjamin Latrobe to add bookending terrace-pavilions. Having transformed the building into a more suitable representation of a leader’s home, Jefferson held the first inaugural open house in 1805, and also opened its doors for public tours and receptions on New Year’s Day and the Fourth of July.
