This sculptural office building, built in 2009, was designed by the prestigious French architect Dominique Perrault. By its balanced play of architectural volumes, it creates and transmits an image of great dynamism that gives energy and movement to its office spaces, accentuated by its elegant black glass facade striated by fine silver, shiny and reflective lines, on which it is projected, in real time, an environment constantly changing due to the intensity of daylight. Located on Diagonal, it has a privileged location in the 22 @ district and offers exceptional views over what has become the green lung of the district, Parc Central. The area, in constant urban improvement, has successfully positioned itself as a new technological and innovation centre of great attraction for multinational companies in their search for and retention of talent. Its consolidated urban area offers excellent communications by public transport due to its proximity to the L4 Selva de Mar and Poble Nou stations and the Tram service. Diagonal 123 houses high-quality office spaces in rectangular-shaped floors with a three-sided façade. Its spectacular terrace on the 9th floor is a unique place to enjoy a changing surrounding whose architecture has become a world reference. The building is certified as BREEAM GOLD.
