Interior of the passenger liner 'Balmoral Castle' (1910) showing the First Class Smokers' Lounge, on the Boat Deck. (a view from the port side, looking towards the screen around the light well at the after end, and showing the clerestory roof). The balustrade around the stairs down to the First Class Lounge is visible in the foreground.

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.
