To the Serpentine, for the Aedas party in Toyo I to 's new pavilion. This is the third pavilion commissioned by the Serpentine Gallery- the first was by Zaha Hadid; the second by Danny Libeskind. This year the engineering was by Arup in general and Cecil Balmond in particular. In fact, Balmond was asked to engineer the project before the architect was chosen, though little has been made of this. As with last year, the pavilion is not to everyone's taste, but there is certainly nothing like it in Britain.
