The tower would have rose as two separate towers, bridged from level 10, all the way up to approximately 300 metres (980 ft) above ground. The structure was to hold a number of skygardens.[2] Construction was suspended in 2009 and the building was never finished.[3][4]
Environmental aspects
There were going to be three large 225 kW wind turbines, 29 meters (95 ft) in diameter, on the building's south facing side in order to generate electricity. These turbines would have had the freedom to yaw, in order to maximize power generation. It would also have been clad in 4,000 solar panels to generate additional electricity. The tower's overall energy consumption would have been reduced by 65%, and its water consumption by 40% in comparison to an equivalent building. At the building's base, a four story glass lobby would have housed an environmental visitor center.[2] It was designed by the Atkins group.[5][citation needed]
