An urban development located in the new area called Porta Firal, which borders the Fira 2000 grounds. The volumetric layout of the complex was our proposal, although with limitations. The buildable area was already defined, and the recommended solution to achieve it was to concentrate it in three skyscrapers about 120 meters tall. However, the City Council—then represented by Pilar Rahola—had agreed with the distant neighbours not to exceed 80 meters in height at any point. This forced us to think of four squat, closely spaced towers. Therefore, we decided to slim down the base of the taller towers to make the platform they rest on more permeable and generous. This is the reason behind their bold structure. Only the central cores for vertical circulation rest on this platform, and only about 10 meters above it do the towers reach their full perimeter. The squat skyscrapers were so close to each other that we proposed having two of them almost touch at their tips, creating a welcoming small square on Passeig de la Zona Franca. The narrow gap between them is almost south-facing (like the rest of the Eixample), which creates a narrow sunlit band that shifts over the square’s pavement—essentially a sundial, whose intricate “sphere” is engraved into the ground. We began the ambitious project in 2004 with a huge underground parking lot. By the time the 2008 crisis hit, we had reached street level, erected the first tower (the isolated one to the west), and construction came to a halt. Only years later, with a substantial reduction in the initial budget, were we able to build the smaller building (originally planned as a hotel) and, eventually, the two nearly touching twin skyscrapers.
