The proposal changes the current image of the building, closed and inert, to convert it into a 'living' structure sensitive to the passage of time and the future new naturalized urban space. Through its new efficient facade, which it seeks to be a contemporary reinterpretation of the traditional facade of Eixample district, it is sought that this new 'organism' evolves, vibrates and breathes, in line with each season of the year. A new building for a new way of making a city.
