Architect Foster & Partners has told the Davies Commission it plans to submit a proposal for a Thames Estuary hub airport in July.
The deadline for registering interest in the Davies Commission - which is looking at air capacity in south east England - was 28 February.
The four-runway airport would be built on a platform on the Isle of Grain in the Thames Estuary. It would have capacity for 150M passengers and extension to six runways. The airport would be connected to London via a spur from the existing high-speed rail line.
“We welcome the Airports Commission – it is an important task and demonstrates the government’s commitment to tackling the aviation issue,” said Lord Norman Foster.
“Decisive action must be taken in planning for future capacity if Britain is to remain competitive. We believe that a new four-runway Thames Estuary airport can best provide the connectivity and future flexibility that Britain desperately needs, while improving the lives of the millions of Londoners blighted by Heathrow’s flight path.”
Foster & Partners and consultant Halcrow is leading the Thames Hub proposal which now until mid-July to submit its proposal.
