It has been said that Farmleigh's Ballroom is a good example of turn-of-the-century social architecture. The Guinness' guests could not fail to be impressed with the superb decoration in the style of Louis XVI with swags, wreaths, musical trophies, urns, sphinxes, and Corinthian pilasters.
The rich decoration is executed in plaster that is applied to wood panelling, and the whole room, including the ceiling, is painted off-white to resemble plaster. The chimney piece is also made of wood and this, together with the overmantel, the ceiling, and the elegant portieres, were all part of an integrated scheme designed by Young. The Edinburgh-based interior design company Morrisons probably supplied the portieres as they had done so for the Young-designed ballroom at Iveagh House.
Hanging from the centre of the ceiling is a magnificent late 19th century cut-glass and gilt metal chandelier complete with coronet. Purchased specifically for the Ballroom, it is on loan from the Guinness family. There is a story that the oak floor was made from disused barrels at the brewery but that has never been confirmed!
