The plans include the building of a floating parking area for aircraft adjacent to stand 1.
I would suggest you open the streetmap
http://www.streetmap.co.uk/streetmap...=180750&zoom=1 in a seperate browser to understand the following better.
The runway is going to be lengthened (I'm not sure by how much) towards the West in the direction of Connaught Bridge.
The primary school which is over the road from the terminal buildings is going to be relocated and this will become the new DLR station. An elevated walkway will also be built to connect to the terminal building.
The current approach road for vehicles to the terminal building is going to be closed with a new entrance being created from Connaught Albert Road.
