Which Spanish architect designed the Casa Milà (La Pedrera) in Barcelona?

The Spanish architect who designed Casa Milà, also known as La Pedrera, was Antoni Gaudí.

Casa Milà was built in Barcelona between 1906 and 1912 as a private residential building. Commissioned by Pere Milà and Roser Segimon, it was one of Gaudí’s final major secular projects and his last completed private residence. Its undulating stone façade and wrought-iron balconies challenged conventional ideas about how an apartment building should look.

Rather than relying on load-bearing exterior walls, the building uses a self-supporting façade attached to an internal structure. This allowed Gaudí to create more flexible interior layouts, while two large courtyards brought light and ventilation into the apartments. The roof is especially famous for its sculptural chimneys, ventilation towers, and stair enclosures.

Casa Milà is often grouped with Catalan Art Nouveau, but in Catalonia the style is usually called Modernisme. It is also sometimes confused with Casa Batlló, another Barcelona landmark by Gaudí. UNESCO added Casa Milà to the World Heritage list in 1984 as part of the Works of Antoni Gaudí.
