Biddy Livesey and Amy Howden-Chapman have been collaborating since 2005. Their work together center around performance, writing and the production of publications. Their work primarily considers the design and use of cities.

Active Edges of the Commonwealth contrasts elements of the street scape around the off site building used by David Dale Gallery at the East End of Glasgow, with Mangere, a post-industrial area in Auckland, New Zealand. Though analysis of photographs of two sites the project considers how buildings in these two locations function. The project also catalogues additions, such as seating, that have been made by those people who use these areas so they can function more effectively.
