The separation distance required by urban regulation of the town, establishes the location of the building in the middle of the plot. The main idea was to do a courtyard three stories high that provides monumentality, transparency of the work places and organizes the functional requirements.From the corner of the plot, a lack of sun protection of the façade announces the main entrance of the building and drives people to the inner hall. The program is organized concerning its privacy. In the ground floor we put, the conference hall, classrooms, cafeteria, and common services. On the first floor, there is the workplace for the accounts departments. And finally, in second and last floor, we put general direction and human resources.On the other hand the Building contains as well a little health centre which has an independent entrance in the opposite corner.Image of headquarters is conferred by prefabricated concrete elements, with U shape in section which is used as a path for cleaning glasses and provides a sun protection to the floor below.
