Ever been trapped in a cubicle on a beautiful summer day? The architects of Tate Hammer, in collaboration with artists Natalie Jeremijenko and Shuster + Moseley, as well as an engineering firm, may have an answer. Titled TREExOFFICE, this pop-up work space aims to get London's workers out of the office and into city parks. The TREExOFFICE, shown as part of the London Festival of Architecture, is a platform on stilts that wraps around a mature tree; it features eight workstations, electricity, and WiFi. Individual desks, or the entire office, can be rented for a small fee that goes towards maintaining local parks.
