Another masterpiece by Gaudi (and the most iconic work of his civic architecture), this spectacular house was built between 1906 and 1912 and commissioned by Pere Milà and Roser Segimon. Casa Mila was in fact the new home of the Milà family (Roser Segimón and her second husband, Pere Milà), who occupied the main floor and rented out the other apartments. Gaudi made his first sketches in his workshop in Sagrada Familia. The building features forms drawn from nature.
