Sustainable urban planning and urban renewal are major challenges of the 21st century. In this context, Urbanism and Town Planning proposes a geohistorical approach to urban construction. The city and its neighborhoods are studied through their materials and general layout, which sometimes reveal a logic of economic profitability, prestige and social equity, and sometimes a more innovative approach from an environmental perspective. Across these elements, unbuilt spaces (distinctive streets and squares) and built spaces (commercial and residential areas, both individual and collective) form a three-dimensional grid of "voids" and "solids", characteristic of urban landscapes and lifestyles. Supported by numerous original examples, this book is a comprehensive summary of the most tangible elements of urban planning and development; elements that must be put into context in order to think concretely about the development of the cities of the future.
