Editing Casa Milà (section)

==== Hall and courtyards ====
The building uses a completely original solution to solve the issue of a lobby being too closed and dark. Its open and airy courtyards provide a place of transit and are directly visible to those accessing the building. There are two patios on the side of the Passeig de Gracia and of the street Provence.

Patios, structurally, are key as supporting loads of interior facades. The floor of the courtyard is supported by pillars of [[cast iron]]. In the courtyard, there are traditional elliptical beams and girders but Gaudí applied an ingenious solution of using two concentric cylindrical beams with stretched radial beams, like the spokes of a bicycle. They form a point outside of the beam to two points above and below, making the function of the central girder a [[Keystone (architecture)|keystone]] and working in tension and compression simultaneously. This supported structure is twelve feet in diameter and is considered "the soul of the building" with a clear resemblance to Gothic crypts. The centerpiece was built in a shipyard by Josep Maria Carandell who copied a steering wheel, interpreting Gaudí's intent as to represent the helm of the ship of life.

;Interior, gates

Access is protected by a massive [[iron]] gate with a design attributed to Jujol. It was originally used by both people and cars, as access to the garage is in the basement, now an [[auditorium]].

The two halls are fully polychrome with oil paintings on the plaster surfaces, with [[eclecticism|eclectic]] references to [[mythology]] and flowers.

During construction there was a problem including a basement as a garage for cars, the new invention that was thrilling the bourgeois at the time. The future neighbor Felix Anthony Meadows, owner of Industrial Linera, requested a change because his [[Rolls-Royce Motor Cars|Rolls-Royce]] could not access it. Gaudí agreed to remove a pillar on the ramp that led into the garage so that Felix, who was establishing sales and factory in Parets del Vallès, could go to both places with his car from La Pedrera.<ref Name=huertas/>

For the floors of Casa Milà, Gaudí used a model of [[floor]] forms of square timbers with two colors, and the hydraulic pavement hexagonal pieces of blue and sea motifs that had originally been designed for the Batllo house. The wax was designed in gray by John Bertrand under the supervision of Gaudí who "touched up with their own fingers," in the words of the manufacturer Josep Bay.<ref name=bayo20>[[#bayo|Bassegoda, 2003....pàg. 20]]</ref>
