In 1948, General Motors opened its headquarters with a building with a new scale on the most emble­matic corner of the recently inaugurated Avenida Los Ilustres. The building, a clear example of mid twentieth century functionalism, was meant for offices, workshops and sales for the Chevrolet brand. The group of volumes, with two low rectangular bodies and one tall rectangular nine-story body, became a reference in the sector. Its differentiated façades show a composition of walls and openings framed according to their function. The low volume intended for sales and located towards the northeast corner, has large windows protected by a horizontal overhang, while the east tower consisting of offices and a blind vertical circulation body, has horizontal windows surrounded by frames as part of the formal language, which act as sun protection. The workshops, a closed volume on the northeast corner, complete the harmonious group of brick covered shapes. The authorship of this elegant building, which was owned by successful businessman Armando Planchart, is attributed to architect Pedro Dupouy. The iconic Cars sign on the façade and the words Chevrolet on the roof and the vertically placed Buick, which were an integral part of the building’s image, have been replaced by a cube crowning the circulation core, deforming its scale and altering its original shape.
