The aesthetics of an architectural project, as a sensitive relationship to the building, is important because it is the link that allows us to interpret through experience. We can then explore its correlation with the challenges of sustainable development (ecological, social, economic) as parameters of a project. Through this text, the relationship between these two concepts is studied, without being opposed, by their mutual impacts and the beauty of their complementarity. Through a parallel with the vernacular, as a qualitative legacy of design methods, it is by drawing inspiration from its lasting qualities and beauty in diverse forms that we can strive for contemporary creation in architecture.
