As climate, culture, and technology evolve and become increasingly unpredictable, architecture's stasis becomes more incongruous. Werewolf explores an emerging but under-investigated branch of architecture that embraces the transformation of form, performance, and the responsiveness to environments and context. These ideas are studied through architectural precedents and framed by critical essays by Jesse Reiser, Greg Lynn, Jimenez Lai, Spyros Papapetros, Kari Weil, as well as the editors. The shift from passive buildings to reactive structures is now imperative, as climate change and political turmoil exacerbate the unpredictability of environments. Werewolf expands on the architect's agency to critically address political, social, and environmental unrest. Revealing the cunning and agile ways in which architecture can negotiate rather than resist change, this book departs from the fixed Vitruvian man and uses the figure of the werewolf to propose a model where changes of state, mutation, and decomposition are conceptually fundamental.
