Royal Navy flagships used architecture to project authority

Who designed Royal Navy flagship interiors for peacetime imperial duties, and how were those spaces made impressive?

Naval constructors designed them, sometimes using forced perspective to make flagship spaces appear more imposing.

Naval constructors already had experience designing capital-ship interiors for peacetime flagship duties. In some Victorian-era ships, corridors approaching the flag spaces used forced perspective to appear longer and more imposing. Room shapes and painted lines could produce the effect, including lines that appeared straight but were not. By the 1920s, such arrangements attracted less attention, with designers instead considering matters such as where guards would stand.
