PROPERTY firm Development Securities is planning a vast raised platform over an area of its Paddington Central scheme to accommodate the route of the £6 billion Crossrail project.
The firm has asked Sir Robert McAlpine, Nuttall and Bovis Lend Lease to draw up initial plans for the £30 million deck, which has yet to be approved.
It is understood that the concrete and steel structure - to be built over the undeveloped part of the site - would measure 150 m by 60 m.
It would stand 12 m off the ground to allow the Crossrail tunnels to pass beneath, while Development Securities would be free to build on top.
Due to the site levels, the deck would appear to be at ground level and would link with the first phase of the development. It would also provide a visual and acoustic screen for the Crossrail tunnelling works.
One project source said: 'This job would involve thousands of tonnes of concrete. You could build another Canary Wharf on top of it if you wanted to.'
A Crossrail spokesman said:
'Nothing has been confirmed yet, but the area has been safeguarded as likely to be affected by Crossrail development. Construction work is due to begin in 2006, subject to approval from the minister.'
