The concept started with security. The front façade has a closed elevation, negating the openings. This is because the front of this official street faces south and no vulnerability was wanted. On the east façade, where there is a secondary access, something more imposing was designed, with an emphasis on volumetry and openings. To ensure the safety of the building, a wall with adjustable visual permeability was designed through the landscaping. Barys, from the Greek, means heavy, and, like the metal Barium, reference is made to this monumental and imposing architecture.
