The project responds to a program for a small hotel located in front of the Barcelona França Station. The solution proposes different treatments to the part of the building that faces the narrow streets and the part facing the avenue. The result is the addition of two completely different bodies. The body facing the avenue is wider, the enclosure is glazed, and the pillars and girders are visible. The back body is a wall structure that houses individual rooms. The staircase concentrates all the vertical dynamism by means of a continuous railing that spirals up to the top floor.

Moragas was one of the founders of R Group (1951-1961) and he was later dean of the Architects’ Association of Catalonia and the Balearic Islands (1964-66 and 1972-74), where he organised a series of international avant-garde architect conferences, such as Alvar Aalto, Nikolaus Pevsner or Gio Ponti. He was also the founder of the Industrial Design Association (ADI), created in 1960 within the Promotion of Decorative Arts (FAD), and president of the FAD from 1968 until his death. He always defended the organic and expressionist conception of Scandinavian architecture opposing it to the International Style.
The Hotel Park is one of the projects that Moragas had in process during the foundation of the R Group and that meant his full affiliation to the modern movement. The geometry of the site is very long and narrow, which would completely determine the conception and distribution of the project. The floor plan is organised around a central corridor, with all the rooms on either side, facing the outside. The main façade coincides with a seven-metre headwall and is the place where Moragas explores all kinds of formal inventions. The lateral façades, on the other hand, are neutral walls cut out by a uniform pattern of windows.

The Hotel Park is defined by the uniqueness of the irregular plot on which it was built. Because it is a building which faces all the angles, three of the hotel’s façades face very narrow streets, the size of the city within the walls. On the other hand, the fourth façade, and for this reason the main one, faces Marquès de l’Argentera Avenue, one of the widest in the city, both at the time of its construction and currently. It is necessary to add to all these urban singularities the conditions of the land itself: on the one hand, crossing the lot, was the Rec Comtal channel; on the other hand, the inconsistent composition of the soil and a water table very close to the surface.

These reasons were decisive in the choice of a mixed structural system of perimeter load-bearing walls and pillars. The composition of the façades responds to the layout of the rooms and the different services of the hotel, except in the main façade, which is only seven metres wide and where balconies open on both sides. Not closing these elements with a side wall helps to dilute the feeling of volume narrowing; the continuity of the railing, the barred beams or the lightness of the partitions are also elements that make this construction singular. In Antoni de Moragas i Gallisà’s words, "this is an ordinary building without any pretensions, as the buildings that are made every day should be".

The treatment of the materials changes its scale on the ground floor, with delicate attention to detail, which is transformed into comfort once we pass through the front door. The building was renovated in 1990 by his son, the also architect Antoni de Moragas i Spa.
