In our latest Steel Intelligence supplement, we look at two innovative approaches to tried and tested building types. At St John Bosco Arts College in Liverpool, BDP took future-proofing to an extreme in its school-in-a-shed design, conceived as a huge column-free space for maximum flexibility. Allford Hall Monaghan Morris has produced a new twist on the student housing tower for Urbanest, which gives lucky residents some of the best views around of central London. Inspired by the form of an Eames stool, the tower combines a sandwich of uses with the help of a hybrid structural solution. We also consider the implications of introducing Level 2 BIM and talk to Hanif Kara about choosing the Leadenhall Building as his steel icon.
