Very British indeed. I've seen pictures of the stationary steam engines that powered the old British textile mills. Here in America, those massive steam engines likely lived in greasy, grimy rooms with oil-soaked brick or concrete floors, but their British counterparts lived in ornate "halls" with shiny marble floors and surrounded by polished brass railings. British steam locomotives, too: where American engines bristled with exposed plumbing and valves, British locomotives wore neat metal sheathing over it all. A very different attitude.
It was all very British and the "transmitter hall" was impressive.
