This project aims to stress everything we considered valuable from the typological housing tradition of the Barcelona’s Eixample. Thus, the type plans are formalized following the distribution of equal (or almost equal) rooms that traditionally characterized the housing blocks of the late s. XIX in the area. A characteristic that has allowed the apartments to modify the way they have been used over the decades without substantial architectonical changes. A seemingly rigid system has allowed nevertheless to change their use in the course of time.
