This is the completion of an office building from the early twentieth century originally left incomplete.
The project involved the completion of one floor that was originally missing, and adding two more floors. The integration has been designed with a trilithic technique; an alternative construction system to the existing building.
The new construction system bears on the existing walls and the three way pillars are finished with traslucent gray glass.
The facade composition is based on two orders of pillars following the A-B-B-A pattern. This compositional system creates a pattern of “Serliana”type openings, as well as the Basilica of Palladio. This compositional strategy adapt the new architecture to the variable rhythm of the existing wheelbases.
The integration of the new architecture creates new openings aligned with the existing windows through the central element of “Serliana”, this element is repeated in the facade composition as a constant element.
Instead, the other two parts of “Serliana” (that symmetrically flanking the central one) act as variable elements; they absorb the alignment differences between the existing openings and the new windows interaxes in the whole facade composition.
