Among his most notable architectural works are the reconstruction of Ludwig Mies van der Rohe's Barcelona Pavilion, and the reconstruction and expansion of the Liceu Theatre in Barcelona.

Ignasi de Solà-Morales coined the term "terrain vague", applied to “free, available, unengaged” parts of the city that are, as urban scholar Stefano Bloch puts it, "left over as underutilized remnants of capitalist development."https://www.taylorfrancis.com/chapters/edit/10.4324/9780203731932-65/painting-insurgent-artscapes-stefano-bloch
