The Calthorpe Project is a unique building integrally linked to a small, multi-use green space on the Grays Inn Road in London's King's Cross. The site was initially established in 1984 after local people fought to save it from development. The purpose built community centre and meeting venue was constructed using highly innovative building techniques about 13 years ago. It now caters for a very diverse range of regular users and occasional visitors. Good definition of space allows for a wide variety of functions and helps to maintain a harmonious atmosphere between the different groups.
