The CityLife project located in the heart of Milan – in the centre of the historic fiera area immersed in a park of 160,000 square metres (one of Europe’s largest pedestrianized zones) — involves a group of architects rather than a single designer: Zaha Hadid, Arata Isozaki and Daniel Libeskind. CityLife brings to the urban context a new model for work and leisure, an area to be enjoyed on foot or by bicycle, with traffic circulating only underground.
