International architecture and interior design practice Antonio Citterio Patricia Viel has unveiled design for the new Milan headquarters of Italian multi-utility company A2A. Reaching at 144-metre height, the office tower – named Torre Faro (lighthouse tower in Italian) – will connect Milan's historic center and periphery by reactivating a north-south axis that runs from the city center all the way to ACPV's Symbiosis business district, located just across the disused railway yard.
