The Flussbad natural swimming pool design (image: united:realities)
The 3rd International Holcim Awards for sustainable construction projects from across Europe were recently announced at a ceremony in Milan, with the German architectural firm realities:united taking first prize for its Flussbad proposal. Led by architect Tim Edler, Flussbad would transform a stretch of the River Spree in Berlin into a 745 meter (almost 0.5 mile) -long "swimming pool." That's about the size of 17 Olympic pools! It is hoped that the project will provide Berlin residents with a new way to use the city's historic center, whilst taking advantage of a currently unused section of Berlin's inner city river.
