The floors of homes were designed by Gaudí so that they could adapt easily to the needs of tenants, since having no load-bearing walls are interchangeable and adaptable. Thus, all plants and almost all floors have different structures, which have evolved with the passage of time: for example, the main floor, the dwelling of Mila marriage, later an office, then a bingo and is now an exhibition hall. This House, the main building, had 1323 m2, with access both Paseo de Gracia and the Provença street, via lift or two large staircases that leave from the entrance hall. It had more 35 different application spaces, including the receiver, an oratory, a room of reception, the office of Mr. Milà, the dining room and the master bedroom; Some rooms received special names, such as «purple room» or the «china». Note the different floors designed by Gaudí according to their function: plates of La Senia stone corridors and halls, Park for lounges and rooms, and hydraulic tiles for kitchens and bathrooms.
The decoration of the main dwelling was one of the most luxurious and detailed building, conducted by Josep Maria Jujol, who designed the furniture and various decorative elements, as well as some details on relief in columns and ceilings, always under the supervision of Gaudí. Highlights a pillar with the Latin inscription charitas (charity), next to the words in catalan sorry (sorry) and oblida (Miss), wrapped in various elements, such as a rose, a cross, a fish fry, a jellyfish, a flower of Lotus, an egg and a M (Maria) crowned; also, the i of oblida shaped sperm. In the same column, below, reads tot the be creu (‘all the good believe’), and o of a 9 concha.nota appears it in another column one lute, in another appears a harp, and in another a dove Messenger and a table ready for a banquete.46 ceilings and moldings, elaborate plaster, Jujol carried out various designs abstract or naturalistic inspired – like sea waves – as well as different figures, symbols and inscriptions, as Maria, the phrase M faces som lliures (“still are free”) or several verses of poems and songs popular catalanas.nota 10 to the owner and Roser Segimon, didn’t this decoration, so sent it to cover with plaster after the death of Gaudí, in 1926.
The rest of housing for rent, were you project by Gaudí with the same dedication, so cared for down to the last detail and intervened in numerous cases in decorative elements and furniture. In general, classrooms and dorms each housing onto the street, while service areas are oriented to the inner courtyards. On the first floor there are three homes of about 440 m2 each one; in the second and third are located four houses, one overlooking the Paseo de Gracia, another to chamfer and two to the Provença street; and in the fourth, there are three houses, one which occupies the area of Paseo de Gracia and the chamfer, and two corresponding to the Provença street. Gaudí included all of them all the advances and comforts for the time, such as electricity, heating and hot water; In addition, each House had a parking place and a storage room in the basement and a laundry room in the attic. The architect cared the most details, especially doors and windows, designed with a fully modernist ornamental style, as they dictated the stylistic canons of the time. In general, these designs had organic inspiration, as drops of water, eddies, jellyfish, starfish, seaweed and flowers. Another outstanding feature are molding of plaster in the door frames and the arches of the Interior of the houses, with several original designs with organic or abstract shapes. Gaudí even designed the latches of doors, made in bronze with again original, and innovative designs with almost sculptural forms. He also drafted numerous designs of furniture, some of which can be seen in the sample of the building floor.
The top floor is the loft, which Gaudí conceived independently from the rest of the building, with an original at the same time plastic and functional structure. This plant, 800 m2, housed the laundry rooms and other areas of services, and at the same time acted as a regulator heat, isolating the building from temperature extremes, both winter and summer. To do this, the architect was inspired in the typical Catalan farmhouse attic, but with a new design based on parabolic arches, which in a succession of 270 brick arches create an autosustentante structure which does not need columns or load-bearing walls, and getting an open space that creates a corridor all along the building. These arches come together in the ceiling in a kind of spine that recalls the skeleton of an animal or the structure of a boat ready to reverse. On the exterior, this loft is located meters deeper than the line of the façade, and is crossed by two lines of small windows, slightly larger than the upper lower. In the space between the attic and the façade is a narrow pass of round that goes around the building, whose route are four small domes of parabolic profile. The loft was remodeled in 1953 by architect Francisco Barba Corsini, who created thirteen apartments for rent, modern and away from the Gaudi project. However, after the acquisition of the building by Caixa Catalunya, in 1996 it was restored, restoring the original designed by Gaudí, and currently hosts the Espai Gaudí (space Gaudí), an exhibition on the life and work of the architect, with models and audiovisual material of the main innovations made by the catalan architect.
