The building has been built on a site classified as equipment by the General Metropolitan Plan located at the intersection of Washington and Cristòfor Colom Streets, in a low-density residential area.
The land has an average longitudinal slope of 14% and borders on the north side with a future linear park area that joins Santa Eulàlia Street and Nord Street. On the west side it borders the wall that closes an isolated single-family building. Taking into account the urban situation and the conditions of the site, both in terms of dimensions and topography, an attempt has been made to place the pavilion at a level that would allow access on foot through the lowest level of the site and that, at the same time, it ensured that the emerging volume above the surrounding streets maintained a similarity with the neighbouring buildings, generally low and two-storey. This approach increases the excavation that must be carried out but minimises the impact of the building on the nearby urban environment.
Access is through the southwest corner, where Washington and Cristòfor Colom streets meet - it is configured through a small double-height arcade, protected by the roof, and allows passage at street level, which is the same as the lobby and sports court. From this lobby, the circulation of spectators and athletes is distributed separately to the stands and the locker room areas. The services for the public, the concierge, the referees' changing rooms, as well as a warehouse and a facilities room are located on this floor.
On the first floor there are four collective changing rooms, and one of them is adapted with access from a passageway in which the lockers are located and which has an exit to the exterior passage that separates the building from the neighbouring construction. This floor is also accessible to spectators by means of a staircase that connects with a balcony located above the track, which at the same time has the function of maintaining and collecting the retractable stands on the ground floor.
The track and grandstand area are located on the ground floor, with a roof with three skylights facing north coinciding with the position of the structure's trusses. Side openings protected with wooden slats have also been provided.
It should be noted that the pavilion has been located leaving a separation strip with both the neighbouring plot and the future linear park, which will open on the north side of the site. These exterior steps are accessible only for maintenance and as emergency exits. An access has also been opened for track maintenance on Washington Street, at the point where it coincides with the street level, equipped with the corresponding entrance.

This project responds to the need of the Santa Coloma de Gramenet City Council to have a pavilion adapted to the regulations and to the track size prescribed by the Catalan Sports Council of the Generalitat de Catalunya for a PAV-1 type multi-sport basic Pavilion.

The building has been erected on a plot qualified as equipment by the General Metropolitan Plan located at the intersection of Washington and Cristòfor Colom streets, in a low-density residential area.

The land has an average slope in the longitudinal direction of 14% and borders on the north side with a future linear park area that joins Carrer de Santa Eulàlia and Carrer del Nord. On the west side it is bordered by the wall that encloses an isolated single-family building. Taking into account the urban situation and the conditions of the site, both in terms of dimensions and topography, an attempt has been made to place the pavilion at a level that would allow access on foot through the lowest level of the site and that at the same time he achieved that the emerging volume above the streets that surround it maintained a similarity with the neighbouring constructions, low and two storeys in general. This approach increases the excavation that needs to be carried out but minimises the impact of the building on the nearby urban environment.

Access is through the southwest corner, where Washington and Cristòfor Colom Streets meet - it is configured through a small double-height porch, protected by the roof, and allows passage at the level of the street, which is the same as the lobby and the sports court. From this hall, the circulation of spectators and athletes towards the bleachers and the changing rooms are distributed separately. Public services, the concierge, the referees' changing rooms, as well as a storeroom and facilities room are located on this floor.

On the first floor there are four collective changing rooms, and one of them is adapted with access from a corridor in which the lockers are located and which has an exit to the external passage that separates the building from the neighbouring construction. This floor is also accessible to spectators by means of a staircase that communicates with a balcony located above the track, which at the same time has the function of maintaining and collecting the retractable bleachers on the ground floor.

The track and stands are on the ground floor, with a roof with three north-facing skylights matching the position of the structure's trusses. Lateral openings protected with wooden slats have also been arranged.
It should be noted that the pavilion has been located leaving a strip of separation both with the neighbouring plot and with the future linear park, which will open on the north side of the plot. These exterior steps are only accessible for maintenance and as emergency exits. An access has also been opened for track maintenance on Washington Street, at the point of coincidence with the level of the street, equipped with the corresponding entrance.
