The exterior is faced with Indiana limestone, while the interior features African Mahogany, Italian marble, terrazzo, gold-plated doorknobs, a silver and gold plated ceiling, ornamental bronze, hand wrought iron and three commissioned busts of George Washington.
In late 2008 the original "Pavimento Pirelli" black rubber flooring on the platforms was replaced with new biscuit-coloured terrazzo floor tiles.
The ground floor includes two retail shops with a central entrance tiled in beige terrazzo, with pink skirtings.
