io9 spoke to Nick Bonner, founder of Koryo Tours who have been bringing travellers to North Korea since 1993. Bonner commissioned an architect to create a series of designs imagining how a future North Korea might accommodate a huge influx of tourists:
Many buildings in North Korea have what we in the West would call a retro-futuristic feel, so something that we have seen before, except this time we were pushing the eco side of it all.
The project was commissioned in-house – an experiment between Koryo Tours and the North Korean architects, and looking at the future of sustainable tourism. When we started taking the first tours to North Korea in 1993, only a small handful of people were visiting, but now we take over 2,000 a year (more than half of all the foreigners who visit). It still remains the least-visited country in the world, but also one of the most interesting experiences possible.
