Airplot

The battle over a 3rd runway for Heathrow became an iconic struggle between those of us who know the climate change threat is deadly serious, and those who preferred to gamble our collective future in search of short-term profit. And when that latter group includes such heavyweights as the Department for Transport and the British Airports Authority, you know you're in for a fight - even when the science is on your side.

In the event it took three years of hard campaigning, and the building of a huge coalition of civil society (including residents' groups Hacan and NoTRAG, local councils, Climate Camp, WWF and RSPB) to bring the runway plans down.

This morning we're proud to announce the winner of the Airplot Contest - our competition to find the ideal structure to fortify the Airplot so that, if the police come to turf us out, we can peacefully resist them. There were two categories - one for architects and architecture students to come up with some practical solutions for how we can defend the land, and the other open to everyone to let their imaginations off the leash.

What would you build on our piece of land to stop the third runway?

Lordy. When we launched the Airplot fortress competition a few weeks ago, I don't think we were prepared for the sheer range of ideas we'd receive. We've had plenty of suggestions for forts of some kind, while others have trod an underground pathway with tunnels and bunkers, and others have gone fully 'outside the box', proposing bold and outlandish new design concepts.
