During this semester my work has been shaped by a series of personal challenges that I have set for each exercise. The first challenge was to make contact with the problem and its magnitude, carried out through a first material exploration and a subsequent compositional rationalization. The second challenge was the connexion of concepts: a material connexion and a connexion of the material with the composition, in such a way that they all condition each other. The third challenge was concretion, a search for greater rigor, trying to apply real measures to a large-scale project. Finally in the fourth exercise I wanted to take the concepts to the extreme and that was only possible with a great trial and error process.
