China’s ministry of transport says around 700 million people, more than half of China’s population, will make 2.85 billion road, rail, air and ferry trips around the spring festival, as the holiday period is called.

Some projects absorb themselves into the original structure. Built in 1876 as a gasholder to supply the lanterns of Berlin, and converted into an air-raid shelter during World War II, the Fichtebunker is the only surviving structure of its type in Berlin. The steel dome of the structure inspired the radial design of 13 new apartments and gardens built into the roof. “Clearly most older urban rooftops are neglected – the sort of ‘junk space’ that Rem Koolhaas has written about,” says Jodidio. “But a combination of rising urban density, high land and construction costs, and interest in ecology have promoted and encouraged the use of areas, even when they are not visible from the ground.” (Credit: Cordia Schlegelmilch)
