The Caretaker’s House at Hooke Park is based on a schematic design by students in Unit 2 of the AA Intermediate Programme in 2009–10, which was later developed for construction by Invisible Studio. It is a prototypical low-cost exemplar building constructed from timber grown and felled on site, used in its ‘green’ state, and is the first green timber building in the world to achieve Passivhaus standards for insulation and airtightness. The building is home to Charlie and Georgie Corry Wright and their family.
