The studio began with a close analysis of the materials consumed and carbon emitted through the activities that contemporary architects are involved in every day: the construction of new development, the dramatic renovation of buildings that are no longer considered fashionable, and the demolition of structures no longer considered useful. Material and energy flows have been extensively researched to plot their rates of consumption, accretion, and dispersal over time on one of the two given studio plots. I also investigate the history, durability, and perishability of commercial structures, particularly by looking at the uncertain fates of retail and office buildings in Birmingham.
