The Conservative MP has set out an extraordinary raft of policy suggestions that would see the current Labour plans replaced with a new city built on land reclaimed from the sea.
The former cabinet minister - who chairs the Tory Economic Competitiveness Policy Group - revealed the bizarre idea in a pamphlet produced in a private capacity.
The 'vision' would see a new settlement of 50,000 new homes called Thames Reach built on the land - thereby drastically cutting the need for new homes in the countryside.
In the pamphlet Redwood suggests that these huge schemes could be funded by selling plots of underwater land before construction begins.
Under the plans, renewable energy and desalination plants would be built into the sea walls.
This is not the first time Redwood has waded into the Thames Gateway debate. In 2004 he called for the construction of Thames Reach, but had yet to formulate the plans for reclaiming land.
