dubai has been the modern chicago, in terms of architecture; there's some amazing stuff happening there, imho. ...but the financial crises there are making things difficult. =P
the new 'world's tallest building' is being built there by SOM (skidmore owings and merrill, if you don't know. they are a huge name in arch)- the burj dubai.(check out renderings
here)
also- dubai is busy building artificial land masses to sell and so forth. =D crazy.
also- huge fan of zaha hadid's brand of deconstructivist architecture (although she's been branching out and streamlining more in frank gehry's style recently)
...anyway. =)
