The government wants to get planning officers "off people's backs" with a relaxation of current rules in England.
For a limited period, people will be allowed to build larger extensions on houses -up to two runways big enough for Jumbo Jets.
The new Permitted Development Rights will make it easier to install conservatories, loft extensions and international airports without going through weeks of planning bureaucracy, the prime minister promised.
Mr Cameron said: "We're determined to cut through the bureaucracy that holds us back. That starts with getting the planners off our backs, and meeting the aspirations of families that want to buy or improve a home."
Already a family west of London have started by adding a new runway, saying "the existing two runways weren't big enough for their pets"
Concern about their work was expressed by their near neighbour, Boris, who said "it interferes with my plans to add multiple runways to my own house". He was also worried their new international terminal would overlook his loo.
