American architect Steven Holl has just been given the go-ahead to build a pair of skyscrapers linked by a cycle and pedestrian bridge 65 metres above Copenhagen's harbour. But he's not the only one with ambitious plans for linked towers.
Other recent examples include proposals for a trio of plant-covered buildings by Vietnamese architect Vo Trong Nghia and a pair of residential buildings in London bridged by a transparent swimming pool. See more linked towers on Dezeen »
