The initial programme for this project described a building complex that was to house the facilities for the treatment and reception of satellite signals, a telephone exchange and premises for the management and sale of these services. These functions were grouped in the two main buildings: a representative building with offices and an exhibition hall with a small bar, as well as a technical building which is the teleport itself. The programme also included a security control and premises for conventional installations. Of all this, only the technical building and those of installations and control have been built. In the technical building, the importance of the network of connections and its frequent modification due to technological innovations finally led to a square floor plan completely surrounded by a perimeter corridor of access and service. To complete the effectiveness of this corridor and the flexibility of the connections, numerous vertical ducts have been placed that allow the direct passage of the installations from the ground floor to all the others, including the roof. A certain homogeneity in the premises that make up the building, the margin of the surfaces and the security with which an evolutionary programme must be treated led to solving the plan with an orthogonal plot. A circular concrete pillar is placed in each of its nodes, and the partitions are always placed within the lines of this grid. It is therefore a perfectly isotropic porticoed structure, in which the enclosures are totally subordinated to the organisation of the framework. Construction and design problems are concentrated, as always, at the edges. To support the corridor, the perimeter pillars are deformed, hinged from a certain height to support some prefabricated slabs located at the height of the false ceiling of the interior premises. The technical building is surrounded by a light enclosure made up of glass and practicable aluminum carpentry, which accompanies the perimeter corridors on the two upper floors and, through them, provides light and views to the work premises. This closure is interrupted in all corners of the building.
