The expansion of the sports complex of the Betsaida club with the addition of new changing rooms and new stands is a commitment project within the neighbourhood. It is located on the border between the sports track and the Masia de Can Rigalt, one of the last traces of the pre-industrial city of Sant Adrià de Besòs.
Some of the commitments are reflected in the creation of an access patio at the entrance of the complex. A perforated concrete block lattice screens the access and separates it from the rest of the courtyard.
The front of the changing rooms faces the sports court, creating access on the same level. The building becomes a border, a thick boundary between complex and courtyard, defined by the programme and reacting to the conditions of the site. Materialised in wood and U-Glass, the façade acts as a lantern at night. Behind it, 5 changing rooms, the cafeteria and the access area fulfill the programme with simplicity. The rear façade, painted white, curves in response to the shape of Can Rigalt.

Completing the set, the deck serves as a grandstand, gathering the emotions and cheers of the spectators. The rear part is materialised in the form of balconies finished in crimson enamelled ceramics. Taking the form of the dressing rooms they cover, and at the same time enlarge the stand and create a square, a viewpoint over the Masia de Can Rigalt. This is the meeting point for the little brothers, who play with their spinning tops while their parents cheer on their brothers and sisters who are on the court.

The construction of the extension is economical, simple and typical of the urban periphery. For this reason, the building entrusts its image to its curved geometry, without pretension in the finishes. Lattice shadows, reflected in the curvature of the glazed ceramics on a white canvas as a background, are enough to achieve the conformation of the place; to conform the limit.

The project is located between the limits of a sports facility and one of the last vestiges of pre-industrial Sant Adrià, the Can Rigalt country house. The project must respond to two absolutely different conditions. On one hand, the activity of the youth and the flat topography of the track. On the other, the variable topological condition of the old country house, practically disused.

This commitment is materialised by generating an access patio to the complex, along the edge of the changing rooms. A patio that articulates the new, in front of the specificity of the pre-existence. This limit is the general and democratic access, by means of a ramp to the runway. The building can also be surrounded by a staircase that gives access from the bar. A gate generated by simple, inexpensive concrete lattice pieces, typical of the periphery, protects the patio and the access.

The application of serialisation-variation processes on the selection of pieces allows this deliberately vulgar element to be re-signified. The front of the changing rooms is located at court level. It is a continuous, translucent, and luminous front on the track. Simply a "screen" made of wood and u-glass dresses up the programme. Behind this you can see the five changing rooms, the bar and the toilets. In their rear part, they respond to the stereometry of the house by being specific in their non-orthogonal geometry.

The cover of the changing rooms is built with a topographic element of tiers, an addition of slabs organised with the same vector of uses specific to the building. The stand is parallel to the track in front, where the activity and bustle of the spectators will accumulate. At its rear, balconies clad in bright red ceramics respond to the geometry of the dressing rooms, causing the appearance of a small, raised square, a viewpoint over the country house.
