The first modern office complex in Barcelona was designed by José Antonio Coderch de Semenat in 1968. This high-rise building (any high tower under 35 meters, otherwise it would be a skyscraper) is located at Avda. Carlos III in Les Corts just behind shopping center El Corte Inglés and it is called the Trade Center Complex.
