The title of the German contribition to the 13th Architecture Biennale is"Reduce, Reuse, Recycle". It explores ways of converting existing buildings as an alternative to tearing them down.
Arts.21 takes a closer look at some of the most exciting projects on display at the German Pavilion and meets the architects behind them - including Muck Petzet from Munich. For more Art.21 go to http://www.dw.de/dw/episode/9798/0,,16156384,00.html
