The Green Room, one of three formal parlors on the south side of the State Floor of the White House, is used for small receptions and teas. The builder, James Hoban, intended the room to be the "Common Dining Room." Thomas Jefferson used it as a dining room, and over the years, presidents and first ladies have used the room to entertain guests. The Green Room is now decorated in the style of the Federal period and includes pieces of furniture attributed to cabinetmaker Duncan Phyfe.
