London architects Alastair Parvin and Lukas Barry have won the Greenpeace design competition to build an impregnable fortress on the site of the proposed third runway at Heathrow Airport in the UK.
The competition, launched last year, was a peaceful protest by Greenpeace to thwart the Heathrow extension.
The winning design, Groundswell, is a structure similar to a burial ground with a tunnel network.
The duo beat 70 others to win the competition, according to bdonline.co.uk.
Actress Emma Thompson and comedian Alistair McGowan launched a Greenpeace campaign to buy land and divide ownership in a bid to prevent airport operator BAA building the extension.
The UK’s newly elected coalition government has scrapped the third runway as well as additional runways at Gatwick and Stansted airports.
