So, instead of demolishing this cool old power station, they reworked it. While I don't give a fiddler's about the retail bits, I think the tour of the original power station control room is fascinating (about 1:15 into the video). Note the wink-wink code for Buckingham Palace.
I guess because I've done work in electrical generating stations, I find the old-style art deco meters and cabinets are just so cool. (And yes, I know what these things do, and what a power factor is. The things you pick up as a technical writer ...)
Anyway, thought you might like to have a look.
