We have won, together with the PMMT Arquitectura team, the first prize for the construction of the new headquarters of the Guàrdia Urbana in Barcelona. Our proposal KOBAN XL will be the first building designed according to a new neighbourhood police model, aiming trust and proximity to the citizens. The public façade, a 70 meters long wall along JV Foix Avenue, minimizes its mass by reducing the height and generating 4 big voids: three patios and a crossing lobby that connects the Street to the forest across the building.
