Boris may have tried to make the capital greener with his bikes, but according to top architects London needs to be greener - and taller - in the future.
A new public exhibition opening this week - The Developing City - will display visions of the City of London in 2050. It will look at how the physical environment of the City - its buildings, public spaces and culture have helped it to thrive as a major business centre, and how it will be in the future.
According to architects, whose visions are on display, The Square Mile will become greener with more parks and riverside walkways, while buildings will increase in height to accommodate continued growth.
The Developing City takes place at The Walbrook Building, London EC4 between 21 June and 9 September 2012.
The exhibition will be accompanied by a series of breakfast talks, curator's tours, walks, building visits and other special events.
