Casa Milà by Antoni Gaudí, also known as "la Pedrera" or quarry, was commissioned by Pere Milà i Camps and his wife, Roser Segimon. Built between 1906 and 1912, it represents a rupture, both formally and structurally, from prior housing styles in the Barcelona Eixample. The key to its technical brilliance resides in both the fact that construction rests on a framework of pillars which generates a freestanding floor, and on its self-supporting stone façade, unsupported by the rest of the building.
The bank CatalunyaCaixa owns the building and has converted it into the headquarters of its charitable works division, Obra Social. A meticulous restoration was carried out under the supervision of Francisco Javier Asarta, Robert Brufau and Raquel Lacuesta. The two large apartments on the "principal" or main floor are reserved for holding temporary exhibitions. The roof terraces and attic have been made accessible; in the latter, you can view an interpretative exhibition on Gaudí: l´Espai Gaudí. The building´s fourth floor houses the Pedrera Apartment, which aims to display the Pedrera building in a dual light: its architecture and its value as a dwelling. Therefore, a period apartment has been recreated and entirely refurbished using original artefacts, showing what life was like for a bourgeois Barcelona family in the early 20th century.
