New plans have been introduced to turn London's Heathrow Airport into a mid-sized city. If those plans ever come to fruition, "Heathrow City" would support some 90,000 jobs and 190,000 people, according to Business Insider. It could also add as much as $13 billion to the U.K. economy.
Three proposals have been put forward for the ambitious plan, which include a factory for customizable homes, civic centers, and a "medieval" city center.
These plans will only be explored further if a new airport is built along the Thames Estuary. There are plans for that, too, but it's still uncertain if they'll ever come to fruition. The U.K.'s Airports Commission will decide on the Thames airport plan in September.
Proposal 1: Hawkins/Brown
Hawkins/Brown's idea for Heathrow City include the U.K.'s first airship port, a factory for customizable homes to fill housing demands in the area, and a large park on the airport's former runways, called the Green Belt.
Proposal 2: Maccreanor Lavington
This plan involves a technology campus, a civic center, a retail hub, and Heathrow's Terminal 2, as well as rehabilitating the airport's grounds and planting trees.
Proposal 3: Rick Mather Architects
In this third proposal, former runways would divide the city into different sections based on specializations like education and leisure. It also calls for a medieval city made of existing and new buildings.
