This project was carried out on commission by the Ministry of Education as a result of a tender process. The difficulty of the topography, the functionality of the terrain and the relationships between the users, were the constraints of the project. The building adapts to the topography of the terrain and separates the uses of pre-school and primary. We studied how to optimize conditions, through orientation and construction, maintenance and energy consumption but without giving up the interior design of spaces. It was designed as a dynamic, cheerful and very functional space, valued positively by the faculty of teachers.
