Jean Nouvel was awarded with the Pritzker Prize. Although I am just a dilettante, I cannot quite understand at all his contributions to modern architecture. Of course he is good, that is indeed doubtless.
But if you compare the Philharmonie of Berlin (1963, by Hans Scharoun) with the Philharmonie of Paris (to be opened in 2012) he is constructing in La Vilette, I think both concert halls look quite similar.
Or have a look at the London Gerkhin (2004, by Sir Norman Foster) and at Nouvel's Torre Agbar in Barcelona (2005).
I really like his Louvre Museum extension project in Abu Dhabi, although I am still not sure about the negative effects of the light on the art works. We have to check that.
