The building underwent extensions by architect James Gandon, as Pearce had died. Gandon was responsible for three of Dublin's finest buildings, the Custom House, the Four Courts and the King's Inns. Between 1785 and 1789 he added a new peers' entrance at the east of the building, facing onto Westmoreland Street. Unlike the main entrance to the south, which came to be known as the House of Commons entrance, the new peers' entrance used six Corinthian columns, at the request of peers who wished their entrance to be distinct from the Ionic columns of the main entrance. Over this, three statues by Edward Smyth were placed, representing Fortitude, Justice and Liberty. A curved wall joined the Pearce entrance to Gandon's extension. This masked the uneven joins of some of the extension, as shown below. The wall, built of granite with inset alcoves, bears little resemblance to the building as it was in its parliamentary days.
