As we’ve been working on our Furnace Park project, we came across Mike Lydon’s excellent Tactical Urbanism 2: short-term action, long-term change 

This free e-book describes ‘a growing number of short-term, often self-funded efforts […] demonstrably leading to long-term change’, taking in guerrilla urbanism, pop-up urbanism, city repair and DIY urbanism.
