The Atlas of Never Built Architecture features the most spectacular unbuilt projects of the 20th and 21st centuries. At times impractical or fanciful but always imaginative and ambitious, the projects included reveal the incredible diversity of ideas that have emerged from the world s most influential architects. Futuristic visions from the likes of Frank Lloyd Wright and Le Corbusier, sit alongside more contemporary proposals from talents such as Norman Foster and Zaha Hadid to show how our built environments could have looked very different indeed.
