The high density of buildings in the area, the absence of large public spaces together with the location and privileged views lead us to conceive the building as a plaza – viewpoint.

For this purpose, the tourist-cultural center is semi-buried and the roof of the building is used as a public space, as a square. The tender involved maintaining several existing facilities (pumping station, caissons) that are “covered” by this semi-raised plaza.

A public space where a large portico or porch rises up to frame the views and, like a sculptural element, tries to be an attraction. A cafeteria and a circular staircase connecting with the space below, give program to this porch,

This space has an amphitheater-grandstand on two of its fronts, which spatially delimit this empty space or square, where concerts, theater, street markets, games or a simple viewpoint can be held.

The surface of the square is interrupted by a circular patio, skylights, a circular stage and other elements that try to break the monotony of the square, in the same way that in an urban square there are kiosks, subways, benches, flowerbeds, etc., without breaking the spatial continuity.

In the same way, stairs or ramps of large dimensions are located at the four corners to attract and generate a fluidity of pedestrian movement, just as in a traditional urban square, the corners are almost always open to the streets.

As the building is semi-buried, the height of the square with respect to the street is a little less than one floor. A large 5 m wide ramp continues the pedestrian path of the sidewalk inviting you to climb naturally.

A certain idea of a citadel or citadel presides over the image of this square, as if it were a defensive building that serves as a watchtower or lookout. Hence, the walls that enclose the building and form the square are thought of as solid marés stone walls, the stone pavements and the ramp as a presiding element that brings to mind the image of a fortification.
