I visited Grow Heathrow a few days ago, it was incredible! This cool girl named Ru showed me around. She was my age and had quit her job about a year ago to live in the occupied green space with other squatters in protest of the proposed third runway at the airport. The space was really colourful and inventive, filled with makeshift living and communal spaces, a shower, a pedal powered washing machine, a cabin, a wind turbine and more! Quite tempted to drop everything and pitch up a tent at Grow Heathrow! Seems like the perfect time for it. Photos below----
