An office in a treehouse in east London's Hoxton Square (where else!)

East London’s Hoxton Square is temporarily home to a treehouse office, as part of the London Festival of Architecture. But as Nathan Barley as it all sounds, it’s actually not all that bonkers an idea, and was devised as a way of exploring how we can sustain and enhance public open spaces. The project was produced by Artsadmin and created by Natalie Jeremijenko in collaboration with artists Shuster + Moseley, architects Tate Harmer and briefing architects Gensler, and comprises eight workspaces for “creative workers” and community groups, who can hire it throughout the installation’s seven month tenure. It’s made of compressed paper with see-through plastic and translucent polycarbonate making up the outer walls, aiming to “blur the boundary between office and nature.”
