Many cities of the developing countries have, for a long time, been burdened with the sprawling squatter settlements constituted of insanitary spaces in ad-hoc structures, overcrowded and inappropriate to the contemporary standards of living. This book presents a novel approach to transforming a number of old squatter settlement into condominium high rises. The problems and potentials for creating sustainable habitats in place of squatter settlements in cities are highlighted. This book also outlines a quantitative study of the holistic thermal capacity of examples of vernacular from a wide range of climates and locations around the world, comparing the results for a range of climate classificatory scales.
