The land on which the following residences are built is the connecting thread of this volume. The plots, be it their topography or geological composition, determine the design of the houses and are a challenge for architects. The allotments` different heights and the geological characteristics define the organization and planning of the structures. Climatic elements such as wind, sun and rain determine the inclusion of energy-saving systems like a tank for rainwater or making use of the breezes to cool down the houses. The surroundings, mainly beautiful landscapes and ecological diversity, delimit the presence of houses, thus we can find some housing integrated into the scenery and other that provokes a clear visual contrast between nature and human creation. This book presents structural and material diversity, ideas for innovation and energy solutions that allow you to get the most out of natural resources.
