Tens of thousands of different tropical plants, 300 exotic animals and a rain forest; it sounds like somewhere in Asia but it is actually Leipzig Zoo in the east of Germany.

The big dome is home to some 40 species from around the world.

All this is made possible by a special cladding system based on plastic cushions filled with air. It is 100 times lighter than glass, extremely flexible but also very strong, for example it can easily support the weight of a heavy snowfall.
