Book excerpt: Re-readings 2 is a companion book to Re-readings, originally published in 2004. This second volume is testament to the growing interest and demand for clarification of the re-modelling, adaptation and transformation processes within the existing built environment. With increased interest in the sustainability and heritage agenda and emerging interest from non-European-centric areas of the world in this type of work, this book explores how the re-modelling of existing buildings is a sustainable and viable alternative to the construction of new buildings. Throughout this highly-illustrated book, drawings and photos of various projects from around the world highlight how the new fits into the existing. Case studies are analysed holistically, and include information on the practical issues and challenges of individual projects.
