In the first episode of this 8 part series from One Voice, Nathaniel Walters of Extinction Rebellion sits down with Dr Larch Maxey of the HS2 Rebellion campaign at a protection camp in Highbury & Islington.

Larch, who is currently living in a tunnel under Euston Square Gardens, gives us an overview of the key elements and considerations involved in the process of building a treehouse and discusses how they are an effective tactic in protecting brownfield sites from developers.
