I loved getting up in the roof of the Pezo von Ellrichshausen installation. The guarding was too high to look over back into the room so you had to look at the ceiling. Seeing the detail of the ceiling at close quarters was really wonderful.
The Li Xiaodong installation gave the sense of being in a forest and the ply boxes little refuges. The doors were much lower than normal but no one seemed to bang their heads I suppose everyone is highly aware of themselves in the spaces created.
The whole exhibition is great, it somehow helps to explain what Architects do without any discussion about taste or style!
