Five years after proclamation of the Sustainable Development Goals promoted by the United Nations, Spain joined this process of transforming the world socially, economically, and environmentally. This research covers the route taken and results obtained during subsequent years in Spain and proposes, as a general objective, to observe whether it is feasible to work in the technical drawing classroom on an eco-urban project, following the learning approach and method proposed by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) in 2017 Education for Sustainable Development Goals: Learning objectives, in order to reinforce cognitive, socio-emotional, and behavioral objectives, as well as the key competences established in Sustainable Development Goal 11. The phases of the project were related to the learning objectives and key competences, the results of which were complemented by a questionnaire that provided information on the sustainable consciousness of the students after completing the project, and could serve as a starting point for future educational projects. We agree with other authors, and in particular with UNESCO, that implementation of this type of project in the classroom is a key learning method for SDG.
