White House, Washington, DC

The White House is a grand mansion in the neo-classical Federal style, with details that echo classical Greek Ionic architecture. James Hoban's original design was modeled after the Leinster House in Dublin, Ireland and did not include the north and south porticos. The presidential mansion is situated on the angled Pennsylvania Avenue at the 1600 block, down the street from the Capitol building, and so is given the address 1600 Pennsylvania Avenue NW, Washington, DC.
