You may have seen the blue doors unfurling on empty buildings around the place. They are the signature of Hidden Borough, the project of the Guerrilla Architects who have been staying in a cold warehouse in Great Suffolk Street Se1 for the last few weeks.
Now they are moving on. Or maybe I should say back. They are returning to Berlin.
Invitations have been issued for a farewell event tomorrow at 55 Great Suffolk Street. It starts at 7pm and they are promising architecture, music, art and performance.
Entrance by ladder only.
