Imagine a chunk of city, more than a third of one million square metres, made from a single cast concrete detail; a district of nine towers up to 14 storeys tall, defined by nearly 12,000 iterations of the same structural module. These are the numbers behind David Chipperfield Architects’ biggest project to date, the City of Justice, which brings together all of Barcelona’s legal services in one complex.
 

The height and width of every block in the City of Justice is determined by its programme. There is no leftover space.
