The American Air Museum at Duxford it amazing, its just a beautiful use of concrete, with the sweeping observation ramps.
Its like saying that you don't care what your car looks like on the outside because you are always in it when you are driving. I remember discussing with an American colleague in Boston about the shoddy feel of the switchgear in a chevy hire car we had and he just didn't get it, its just a switch he said, who cares if it feels and sounds luxurious when you rock it. Detail is important, its about micro and macro. Tell me that the National History Museum isn't complemented by its building. Its all important, not just one aspect or another.
Lets be honest, the TM was a shoddy set of drafty buildings with Gauntlet restaurant when I first visited in the early 1990s, when I went back in 2011 it was so much better. It actually felt like someone cared about the exhibits and most importantly cared about the people who were visiting and paying for it all.
I could park up a Sherman V in a hanger with a small card information sheet propped up in front of it - Tank Displayed.
Alternately that same tank could be in a warm modern building which is pleasing to they eye with a movie of it in use playing, an engine sectioned next to it, veterans combat accounts, examples of ammunition etc...
