The building- of which most of the guests there hadn't heard- maybe was a winner because its intended transformative social role is, for once, genuine- making a historic but practically derelict site live again. And its opening up of an urban block with revived old buildings as well as some spectacular and strangely beautiful new ones is worth far greater acclaim.
I took the award to them in December and was also able to explore the Praca more fully with its architects.
