An original solution to the problem, very common in Barcelona, of constructing an apartment building on a gap site. The plot, close to the corner with Calvet St., has an extremely narrow opening onto the courtyard in the interior of the block, and thus very little opportunity for natural light or ventilation to the rear. It was decided to give the building an internal courtyard of its own, oriented towards the point of contact with the communal courtyard. This new courtyard provides a shared space for all the apartments, letting daylight into the stair well, the houses themselves and the entrance hall. Given the asymmetrical disposition of this courtyard, it was necessary to devote considerable attention to working out the distribution of each apartment in order to ensure individual privacy in spite of the high proportion of space devoted to communal use.
