Interior of the passenger liner 'Balmoral Castle' (1910) showing the First Class Lounge, on the Promenade Deck (a view of the starboard side, looking aft towards the balustrade around the oval well). On the right side of the image are the stairs leading to the Smokers' Lounge. The First Class Lounge was decorated in a variation of the Neoclassical style.

The main public rooms on the 'Balmoral Castle' were designed by the architect William Flockhart (1854-1913). Flockhart trained at the Glasgow School of Art. After a year of study in London and Paris in 1878-79, he entered the office of William Wallace at 27a Old Bond Street, London. He set up his own company in 1881. His clients included Joseph Duveen, the Derwent Valley Water Board and the Union-Castle Mail Steamship Co Ltd.
