In a rural environment, with extreme temperature conditions, a proposal is put forward that, in addition to creating a series of modules of gradual growth, allows the own building’s enery energy and the most sustainable response to the surrounding context. This is how the proposal, far from going to sensationalist forms, is based on the development of a module of easy construction and adaptability, not only because of the materials in which it is made, but also because of its scale and the simplicity of its construction system. All thought in such a way that it can provide the best shelter and the best way to grow to develop a complete building that fulfills the mission of the school.
