In 1988, Xavier Fabré graduated in architecture in Barcelona. During his studies, from 1985 to 1988, he worked in several studios, publications and exhibitions. He also taught as an assistant at the Faculty of Architecture in Barcelona, from 1989 to 1994. Fabré set up a studio in 1988 with Lluís Dilmé, Fabré & Dilmé, where they undertake a great number of projects in many different kinds of spaces, educational, residential, sanitary, museums and exhibitions, and public spaces: L'Escola d'Ensenyament Integrat de Música I Dansa Oriol Martorell (1995-1997), or various livings in El Prat de Llobregat (2002), Girona (2002), or Figueres (2002).
Having worked with Solà-Morales in theatre projects, the three architects assumed the restoration of Barcelona's Opera, the Gran teatre del Liceu, with Eulàlia Serra. In 2000 Solà-Morales, Fabré and Dilmé were awarded the Cultural Heritage National Prize handed by the Catalan Government (Generalitat). They had already been consulted in 1986 before a fire destroyed the theatre in 1994, thus their restoration plan became a reconstruction and enlargement project. They worked on rebuilding the Opera "as it was before, where it was", updated in all the technological aspects.
