'Working as an architect: parking in the basement' is an interdisciplinary project of Technology, Mathematics and English with students of 2nd ESO. The students, in groups, design a 3D parking lot for different types of vehicles, taking into account the current regulations (electric vehicles, spaces for disabled people, motorcycles, bicycles, ...). On a plan and a series of requirements already given by their teachers and using the computer program Tinkercad, the students design their own parking lot.
