After several versions, the ground plan was defined as an irregular hexagon, formed by the perimeter union of the double hexagon proposed in a previous version. The program consists of four bedrooms, a living room, the kitchen and the toilet, with independent uses. The entire program is on the first floor, which is accessed through a staircase located in the centre of the floor, and whose body is the only support for the entire building.
In the construction plan, a mixed structure was proposed, consisting of a metal skeleton, vertical planes built with a double sheet of ceramic work, and horizontal enclosures with brick vaults of ceramic plane. The use of any of these elements may seem contradictory, especially the combination of the light metal structure with the heavy enclosure of the factory. This suggests that the original intention was probably the placement of prefabricated enclosure elements, as can be inferred from the modulation of the façade. All in all, the final solution involves the combination - at least original - of traditional construction elements included in a totally innovative structural system. The body of the central staircase included six perimeter pillars (in an equidistant position with respect to the centres of the two theoretical original hexagons) on which the entire construction rested. The rest of the metal structure, built using UPN and L profiles, was arranged in the form of a double bracket, in such a way that a large part of the load was transmitted in traction from the braces arranged at the top of the pillars.
