Pedro Milà i Camps, a rich businessman was impressed by the Casa Battló, an expressionist building designed by Gaudi. He commissioned Gaudi to construct an apartment building on a corner site at the Passeig de Gracia, in the Eixample district.
The result is a less colorful but nevertheless an even more unconventional building than the Casa Batlló. It breaks with traditional architecture by using not a single straight line. The building does not use load-bearing walls, but rests on pillars and arches. Together with the use of steel this allowed the architect to create completely irregular floor plans. Even the height of the pillars and ceilings differ from one to another. In order to allow light in all the
Balcony rooms, - the apartments are arranged around two central courtyards, one circular and the other oval shaped.
La Pedrera - On the outside, the undulating balconies look like a series of waves. The iron-wrought balconies were designed by Josep Maria Jujol, who improvised on the spot. Some people see the facade as a cliff-like rock with caves. During construction, people dubbed it a quarry, or 'Pedrera'. To date, people still call the building 'La Pedrera' rather than 'Casa Milà'.
Interior - The top floor, attic and the extraordinary roof are open to visitors. The apartment on the top floor gives an idea of how the interior must have looked at the beginning of the 20th century. Just like on the outside, the interior has virtually no straight lines. The attractive rooms have a lot of character, with a mixture of expressionist and Art Nouveau styles. The attic houses an exposition of Gaudi's works, with photos and scale models of his buildings.
Roof Terrace -The roof is probably the most extraordinary of the building. It features a number of surrealistic colorful chimneys. Many of them look like warriors in a science fiction movie, others look more frivolous. The roof also features a bench similar to the one in Park Guell. From the top of Casa Milà, you have a nice view over the Eixample district.
