The park is the result of the purchase by Barcelona City Council of the urbanisation of a luxury neighborhood designed by Gaudí and promoted by Eusebi Güell that never came to be. What can currently be visited are the landscaping of sixty undeveloped plots at the foot of Mount Pelada, with magnificent views of Barcelona, and the common parts of the project: the paths, access, market, central square. Gaudí urbanises the mountain with streets that follow the minimum sloping lines and four bridges built with material from the clearing of the plots. The retaining porch walls inside which can be circulated, covered with local stone, are exceptional. Both the bridges and the porch are crowned by unique columns crowned in turn by planters where agaves are planted. The heart of the urbanisation had to be an elevated square that instead of a perimeter railing has a corrugated bench designed and built with prefabricated concrete by his collaborator Josep Maria Jujol, finished with some breakwaters that are worth discovering in detail. Below the square is a hypostyle room that was to house the market, with twisted columns to work with as little effort as possible. The columns are empty and below them is a water tank that should cover the entire park. Some are removed in order to make room for larger stops and are replaced by medallions, also designed by Jujol. The ensemble is accessed by an imperial staircase that has, on the axis of symmetry, a spectacular dragon made of trencadís that has become one of Barcelona’s landmarks. The fence that guards the park at the entrance, finished with two asymmetrical pavilions, is equally remarkable. One of the pavilions currently houses the Gaudí Museum.

Refurbishment of the Hypostyle Hall, the square and the perimeter bench. Park Güell was a real estate operation of 60 houses for the Barcelona bourgeoisie that failed, and in 1922 the city council bought it and turned it into a public park. The park has never seen its architecture change. Since the 20s, there have only been some punctual repairs and touch-ups. The vegetation has changed and grown, and that sparse and stony image of slopes and ravines is no longer offered to the eye; immobile and permanent vegetation, pruned into stone. An architectural and abstract garden of a rocky nature; a sculpted bare mountain with stone vegetation quarry. The Hypostyle Room is a Greek-style temple with exaggerated Doric capitals and with a dented ceiling with little domes. It supports a dirt square with a wavy edging-bench; a border of acroteria of wave crests with encrusted crustaceans that bring the sea from the horizon closer to the bare mountain. Restoration works of the Hypostyle Hall and the square. Repair of structural elements in poor condition; waterproofing of the roof, and construction of an efficient drainage system; reconstruction of artificial stone coverings of column shafts, capitals and architrave; replacement of tiles on lintels, domes and perimeter bench.

The project was conceived with the intention of improving and maintaining the image of the current building, of considerable dignity. The proposal tends, rather than a transfiguration of the building, to a better use of the surface. The reform project has two intentions: On the one hand, to arrange the different parts of the program to obtain maximum profitability of the space, solve the building's vertical communications by adapting them to fire regulations and, on the other hand, to solve the volumetric problems of the building, consequence of the latest additions. Thus, parts of the building are removed, improving its relationship with the immediate surroundings of the Hypostyle Hall, causing an exit at the level of the room of the columns, tangent to the retaining wall, enriching in this way the routes through the park. The fundamental operation of the project consists in the transfer of the current entrance door, thus facing the new staircase and elevator. This makes it possible for us to have the entire free floor of the wing facing south and west. The attic of one wing of the building is converted into a multipurpose room by removing the cover and turning it into a roof. The dining room and kitchens are on the ground floor with their corresponding services, the patio and concierge changing rooms. The three kindergarten classrooms are on the mezzanine floor, and they have a separate staircase from the general one, which at the same time leads to the gymnasium. This is located in the old greenhouse. The administrative offices are located in the west wing of this floor. On the first floor, there are three classrooms and the library in the south-facing wing and a workshop classroom, two tutorials and a department in the west wing. The toilets are located at the ends of the floors. On the second floor there are three classrooms in the south wing and two classrooms in the west wing. On the third floor there is a multipurpose room in the west wing. Above it, on a higher level, the boiler room and the space for the elevator machinery are found. We have tried to control the holes and windows of the building, repeating on some occasions the existing ones and introducing a new type of window, which in the form of a large lattice, provides light and ventilation to the new dependencies, mainly those of services.
