The building has a south facing elongated volume, and includes a longitudinal central patio with overhead lighting. Thus, it achieves a perfect control of sunlight (in winter the building can have the maximum amount of direct sunlight and in summer has the highest possible level of sun protection.)
The building behaves quite differently in winter or summer, and can be reconfigured easily to move from one state to another.
In winter, the building became a large greenhouse, solar radiation, obtaining the highest in the south. Underfloor heating complements the needs of building heat.
In contrast, in summer, the windows are closed completely south, through sliding panels and the building is illuminated by indirect sunlight from the north and indirect solar zenith central covered courtyard.
From a formal point of view, the composition of the building has made an apology to the reinforced concrete slabs with which it is built. Therefore, and in a poetic form, the building consists of a succession of plates, high up. Thus, the building resembles a grand staircase ascending. A "stairway to heaven."
