I am a huge modernist/minimalist, and I usually can't stand postmodernism, but there are a few buildings I can truly consider neo-art deco.
Wells Fargo Center, Minneapolis
That building in Frankfurt
Key Tower, Cleveland
99 Church Street, NY
and a few others...
What I find really irritating is that many postmodernist buildings use non-matching facade types, such as concrete and glass, and end up turning incredibly tacky and bland, and ruins the entire 'neo-art deco' title. For example, Liberty Place in Philadelphia and this hideous thing:
If only there were more architects that use real art deco elements, and not ugly blends of styles. I would be even MORE impressed if an architect would reintroduce 'neo-gothic' styles!
