Casa Milà, also known as “La Pedrera”, is a modernist building located on Passeig de Gràcia in Barcelona, on the corner with Carrer de Provença. It was the last civil work designed by Antoni Gaudí and was built between 1906 and 1912.
It was commissioned by the businessman Pere Milà i Camps and his wife Roser Segimon i Artells, a native of Reus and widow of the wealthy Indian Josep Guardiola i Grau. At the time it was very controversial due to the bold wavy shapes of the stone facade and the twisted wrought iron that decorate its balconies and windows, designed largely by Josep Maria Jujol, who also designed some of the low ceilings of plaster.
Architecturally it is considered an innovative work as it has a structure of columns and floors free of load-bearing walls. In the same way, the façade – entirely made of stone – is self-supporting, in other words, it must not support loads from the plants. Another innovative element was the construction of the underground garage.
