Based on design methodologies and tools, a general understanding of the ‘Leça Green Corridor’ is proposed, and in particular its specific features, in order to build a coherent and legible narrative that values, adds to and promotes the relationship between the watercourse and its banks and recovers and enhances the associated small constructions, such as paths, mills, weirs, levadas and bridges. In this course, which is part of the Blue Design Alliance, the necessary synthesis of the thinking model for project development aims to stimulate the use and reuse of simple and available materials combined with assembly techniques and construction logic, resulting in a project economy that allows transformation strategies to be implemented in objects built by the students.
