Architect James Hoban's original floor plans show a similar room, but with single columns separating the Entrance Hall and Cross Hall, and with the Grand Stair entering into the Cross Hall. Mid-19th century photographs show the room as rebuilt by Hoban following the 1814 White House fire. In these photographs two Ionic columns support a series of shallow arches, and a frieze of bas-relief anthemion encircling the room. The shafts of Hoban's columns are recorded as being a blue marble.
