Presenting the state-of-the-art in sustainable retrofits in post war residential towers, this book captures and re-informs the current intense refurbishing process that is taking place in Britain, which is part of a global phenomenon happening all over the world, as cities upgrade their building stock in an attempt to comply with governmental emission reduction targets. The authors present inspections of 20 sustainably retrofitted social housing towers, analysing their aesthetic and technical modifications, as well as the shifts occurring in their social structure. The authors use over 200 full colour plans, elevations, photographs, maps and illustrations to beautifully support the statistical and analytical information collected. Finally they include interviews with some of the architects who designed the retrofits, residents and key stakeholders to inform the conclusions.
