Constructed in the city of Buenos Aires, on a lot measuring 8.66 metres wide and 23 metres deep, this building, a printing works covering 220 square metres, consolidates the edge of the city with a metal wall rising the height of the ground floor and first floor. Use of resources which are very basic, in terms of both structures and construction techniques, allowed the architect to employ a vocabulary that might be defined as 'expressively austere'. The ground floor, a uniform, windowless white structure that seems to be intentionally limited to the function of base, barely reveals the location of the entrance door and the loading and unloading bay for printing material. But the first floor opens up toward the sky, letting daylight in through a series of metal fins which dematerialise the building's mass to create an elaborate counterpoint of solid and empty spaces.From the outside, the transparency of the hermetic crystal wall reveals the different degrees of depth in the building, while from inside, a tree provides shade from the sunlight, its perennial green mass standing between the metal fins and the sky. As the project was intended to be an elaboration on an architectural structure, space is expressed by the naked vocabulary of this structure and the elements composing it, which, playing with light, express their strong artistic value while at the same time interpreting the building's various functional requirements. The deep volume of the printing works is illuminated by four skylights which evenly light up the whole surface, and a system of glass walls ensures the space is perceived as continuous right down to the back, where the bright light of the entrance hall dominates the void.
