This chapter provides a theoretical frame work for understanding the governance of urban retrofitting as well as empirical answers to the question of the character of retrofitting governance. In the first section the people develop and implement a framework for understanding the governance of urban retrofitting that considers the assemblage of institutions, materials, agencies and mechanisms that might enable the transformation of cities. The second section presents a more detailed examination of retrofit governance at the 'sub' urban scale, using an audit of local scale retrofitting initiatives in Australia's largest city Sydney to develop a typology of means or techniques through which retrofitting is governed. Developing the argument that an understanding of governing retrofit requires attention to the mechanisms and techniques through which conduct is conducted. It also concludes with an analysis of the limitations of retrofitting governance as currently practised and reflections on the purchase of demonstration as a governmental technique at citywide scales.
