The development will usher in a new quarter for lively Upper Street, with 263 homes, boutiques, bars and restaurants, a theatre rehearsal space, health club and cinema. The four-and-a-half-acre site’s grand double-arched entrance, once only used by postal delivery vans, has been opened up and a new shopping arcade, right, and civic square created. There will be an acre of green space across the rooftops of restored buildings, along with newly built apartment blocks.
