Thomas Heatherwick who designed the London 2012 Olympic Cauldron has been commissioned by Transport for London to design  a £60 million garden bridge across the Thames. The idea of the bridge will be to connect North and South London will a beautiful garden of trees and flowers that are unique to the area.

Joanna Lumley, a local advocate said to the UK's Evening Standard: "This garden will be sensational in every way: a place with no noise or traffic where the only sounds will be birdsong and bees buzzing and the wind in the trees, and below the steady rush of water. It will be the slowest way to cross the river, as people will dawdle and lean on parapets and stare at the great cityscapes all around; but it will also be a safe and swift way for the weary commuter to make his way back over the Thames...I believe it will bring to Londoners and visitors alike peace and beauty and magic."

The project could be finished as soon as 2016.

London also may be the home to a new floating airport, proposals revealed. The upcoming airport, London Britannia Airport would involve four floating runways that are tethered to a sea bed located in the Thames Estuary.

The architecture firm Gensler has designed the floating airport which would allow for expansion of up to six runways.

Project director, Ian Mulcahey told the BBC in September, "The airport can be quickly manufactured in the ship yards and steel works across the UK and can be floated by sea and positioned in the Estuary. This isn't a London airport, it is a global airport, designed, manufactured and built in the UK."

London's the Daily Mail said that the airport will be nicknamed after Boris Johnson, London's mayor with the nickname "Boris Island."

At the airport, which would be connected to London by high speed rail, passengers would be able to check in and arrive at the terminals on land. One would be in Central London between Canary Wharf and the Olympic park and two to the north and south of the estuary.

The Daily Mail said that "the Gensler scheme would see Heathrow Airport close and become a new eco-city and 'the largest urban expansion project in Europe', with housing for around 300,000 people."
