"This building, built for the State Telephones Company - ENTEL -, is a complex of offices and telephonic exchange packed in a large prismatic volume of expressive plasticity and strong texture, whose language, belonging to the second moment of Modernity, announces the brutalist esthetic the Studio would bring to it climax at the Bank of London.
It is separated from the ground by a series of hard columns, which laid down in a free ground floor, according to the correct observation of the architect Federico Ortiz. There are also fixed solar shading separated from the wall, typical of the time. Although, the new remodeling of the building, still in execution, continues transforming many of the original elements."

"Begun when he was 50 years old, this was Kahn's first major work and the one that launched his extraordinary, late-flowering career. It was also Yale's first modern building. The reserver, street-respecting exterior attracted little public notice at the time, but the exposed concrete ceiling and round stair tower with the form-work showing were such publicized - the first sign that many had seen of what would soon become familiar as Brutalism. The interior has now been altered - it was said that it "lacked elegance" - and the original floating partitions have been replaced with white walls, partly concealing the concrete frame. Out back a sculpture garden and the cout of Weir Hall make on of Yale's most idyllic outdoor places."
Yale's first modern building, and the first sign that many had seen of what would soon become familiar as Brutalism. The discreet exterior façade and entrance with exposed brick panels establishes a contrast with the interior spaces, defined by exposed concrete slabs of the floors, whose triangulated, tetrahedral shape in reinforced concrete. A central service zone includes a cylindrical hollow for the triangular stairs with a top lightning that repeats the triangle/circle motif.
