Rem Koolhaas, the architect whose ties to urbanism run so deep that his firm is even called the Office for Metropolitan Architecture, has shifted his focus to the countryside.

His recent research obsession will be the subject of “Countryside: Future of the World,” an exhibition planned for the Guggenheim Museum’s spiral rotunda in fall 2019, the museum announced on Wednesday.

The exhibition — organized by Troy Conrad Therrien in his most ambitious project since he was hired as the Guggenheim’s first curator for architecture and digital initiatives three years ago — will explore how the world’s rural landscapes have been altered by technology, migration and climate change.
