There are countless types of exploitation of limits as a starting point for a project; the limit defines a filter during the design process. Inside a large and wooded space, for example, the “Natural element” can be considered, to some extent, “limiting”. It requires the exploitation of complex spaces in terms of composition and needs. In that case, it is appropriate to understand the spatial relationships between man and nature. Each project must be identified in the needs of both these spheres in symbiosis. It is not possible to accept the hypothesis of a project that doesn’t plan the development of Nature and Artifice together in a single process. Considering Nature as limiting, but generative factor, it is possible to plan a more complete design hierarchies and project.
