George V's wife, Queen Mary, was a connoisseur of the arts, and took a keen interest in the Royal Collection of furniture and art, both restoring and adding to it. Queen Mary also had many new fixtures and fittings installed, such as the pair of marble Empire style chimneypieces by Benjamin Vulliamy, dating from 1810, which the Queen had installed in the ground floor Bow Room, the huge low room at the centre of the garden façade. Queen Mary was also responsible for the decoration of the Blue Drawing Room. This room, long, previously known as the South Drawing Room, has a ceiling designed by Nash, coffered with huge gilt console brackets. In 1938, the north-west pavilion, designed by Nash as a conservatory, was converted into a swimming pool.
