Canary Wharf Group contributes £150m to Crossrail and will design and build
Isle of Dogs station
http://www.tfl.gov.uk/corporate/medi...tre/10895.aspx

A sum of £350m of the station's £500m costs will be met from Crossrail's
£15.9bn budget with Canary Wharf Group (CWG) bearing the risk in relation
to costs above the fixed price limit. With final planning approval received
by CWG, construction of the new Isle of Dogs station will now start in early
2009. The station box is expected to be completed and handed over to
Crossrail by summer 2012.

Planning approval has been received for approximately 100,000 square feet of
retail space and a rooftop park above the station.

The park is a focal point of the design and will be semi-covered by an
elegant and environmentally sustainable timber lattice roof, providing views
of the docks and Canary Wharf beyond.
