As part of a project with the Koryo Tour group, an architect working in North Korea was asked to design buildings suitable for sustainable tourism with no constraints on cost or possibilities.
The aim was to tap into the creative spirit of those living and working in the DPRK and the results are currently on display at the Venice Architecture Biennale in Italy.
