Due to the necessity of a strong financial control and endow the thought of building infrastructures for a future easy access maintenance, the global cost of the work was restricted in a pre-established value by the City Council of Viana do Castelo. Demands which became a true challenge in the way of thinking to respond to what was requested. Hence, the use of the brutalist image in the project without being taken to extremes, perceptible in the change rooms and sports field. It was with this intention that Valdemar Coutinho Architects devised a Pavilion, reflecting the various program and budget demands with an appealing dynamic and humanized image, minimizing the common impact in these types of buildings.

Due to the limited land, the project occupies practically the whole area. The dimension of the programme was developed on a floor at a ground floor level with a secondary storage area. The surface for sports practise is 650 m2 (to play volleyball and basketball essentially) with a height of 7.50m, with 4 independent blocks of change rooms, 2 blocks for the athletes, each one with a capacity for 15 to 20 sportsmen and another 2 for coaches and referees. In the union of the two bodies, the main entrance is developed, where 50/80 people can wait until they find seats.

In this jockey ball around the entrance, a reception, a surveillance post, a cafeteria which operates punctually according to the necessity, a technical support area, sanitary facilities for males and females as well as for those with reduced mobility. Volumetrically, the pavilion, in general terms, is made up 2 parallelepiped bodies (East and West body) perpendicularly implanted between themselves, forming in their whole a unique volume of dynamic and restrained lines. The building predominantly presents two finishing materials, the apparent concrete and grey-bluish stapled stone tack.

The general tone of the building is grey, which reminds us of the beautiful grey sea, in the same way the entrance hall has various panels of grey embossed tiles, allusive to the crustaceans and the algae of the Viana do Castelo beaches.
