Oscar Pedros – “Thinking on a 21th. Century library -as a friend of mine would say-, is like wondering about a book´s cemetery”. At that point, all efforts must conciliate architectonic non-variable values as sequence, promenade and staying with immateriality brought by new technologies. There is no other solution than sharing jealously material space with virtuality to avoid Carballo´s newest building ending as book warehouse. The building is placed in Carballo, a medium-sized spanish village (30.000 inh.), 35 km. far away from A Coruña, Galicia, Northwest Spain. Urban atmosphere is strongly rude, full of party walls and unfinished housing blocks. The building becomes quite hermetic and opens itself to an inner patio acting as an open space for reading.
