Architects HawkinsBrown, Rick Mather Architects and Maccreanor Lavington have revealed the designs of a new town, Heathrow City, proposed for construction on the Heathrow Airport site in London.
Designs for the Heathrow City were commissioned by the UK mayor's office and Transport for London earlier this year, and include development of a new park land, scientific research centres and a factory for building modular housing units.
In addition, the development will include a technology campus and conversion of Terminal 2 building into a civic and shopping centre.
The project is expected to provide homes for around 190,000 people and create 90,000 new jobs.
The Mayor of London Boris Johnson said: "The demand for new homes and jobs in the capital is such that we must be ready to start redeveloping Heathrow the moment it moves to its new site.
"We asked our architects to be as creative as possible and these designs illustrate strikingly different visions of a Heathrow of the future.
"However the key point is that all these scenarios would potentially create some of the many thousands of new jobs and homes this city will require given London is expected to increase in size by a fifth within the next 15 years."
HawkinsBrown partner Darryl Chen said: "Heathrow City should be a platform for innovation on a massive scale.
"We want to capture the same pioneering spirit and romance that characterised Heathrow's first airborne adventures. We hope our vision inspires other new ideas about Heathrow's and London's future."
The project is expected to add £7.5bn to the UK economy.
