We have been following, with great interest, the new urban and local initiative strategies promoted by the municipality of Barcelona. It was with surprise, and unmistakable honour, that we received the invitation from Janet Sanz - councilor for Ecology, Urbanism, Infrastructure and Mobility - to participate in one of the several competitions that the city was promoting for the construction of the new superblock in Eixample . Our proposal, carried out in collaboration with the friend and expert on Catalan reality João Seixas, did not win but allowed us to better study the incredible urban experiences that are taking place in Barcelona.
