The Waterloo Gallery is the final element of Benjamin Dean Wyatt’s work on Apsley House completed in 1830. The style is French revival and has been described as after Louis XIV, Louis XV or Louis XVI. In reality it is an eclectic mix which was a hallmark of Wyatt’s work. The gallery is double height; there is no second floor or attic in this part of the house. When Wyatt’s designs for York (now Lancaster) House were delayed in 1826 they were re-worked for Apsley House.
