Designs, from three firms of architects, include proposals for new park land, scientific research centres and a factory for modular housing units to make it easier for people to build their own homes.
- Hawkins\Brown - This is the one that includes the factory-for-homes plan. Online customisation would allow Londoners to order homes to their own specifications as is common in a number of European countries, where 'self-build' is a popular way of creating new homes
- Rick Mather Architects - Their proposal would see the Heathrow site evolve to become a new hub city by working with the existing structure and using the terminals as generators to development. The former runways would define the structure of the city and connect 10 distinct local centres.
- Maccreanor Lavington - Their vision for Heathrow City aims to develop a fully functioning city within the metropolis, characterised by a rich mix of ecology, culture, employment and liveability. Existing buildings would be used to establish fresh development and new forestation is laid down.
