The book aims to demonstrate a methodology to achieve a green and cheap architecture using containers. Shipping containers were designed to provide an economically viable way to store and transport goods over long distances in watertight conditions. Their dimensions were internationally standardized, particularly in terms of height and the shape of the enclosure itself. These standardized dimensions as well as being economic and secure also happen to be almost perfect in terms of human scale, meaning they are entirely appropriate for designing habitable spaces. Green Container Architecture 3 features four advanced container projects designed by renowned architect and expert on sustainability, Luis de Garrido, that are analyzed in depth.
