The majority of the books could not be saved from the flames. The structural repair of the building was planned to be carried out in four stages: 1996–1997 (financed by a donation from Republic of Austria), and 2000–2004 (financed by a donation from the European Commission), and the city of Barcelona among others. The third stage ended in September 2012, with an estimated cost of KM 4.6 million (about €2.37 million) and will return the city hall to its former grace. The fourth stage began following the completion of the third stage and lasted about 20 months, finishing at the end of 2013 and cost of KM 14 million (about €7.23 million) which are secured through the IPA. In this stage the entire interior of the building was rebuilt and reconstructed (paintings, sculptures, books), resulting in the library being brought back to its pre-war condition. Everything that was possible to restore has been done so, while those things that were not possible to save have been made anew through special molds. The whole reconstruction and restoration process was predicted to cost about KM 25 million (about €13 million).
