In København, public amenities and infrastructure reign as king. Innovative playgrounds, copious places to swim or relax in the sun—boy, do they know how to enjoy the summer! Winters can be brutal with days as short as 7 hours. What if you could close your eyes, lay on a deck, and feel like it’s summer? Imagine an ETFE enclosure orbiting a massive glowing sun, with a thermal slab and sauna powered by the waves. Winter might not seem so eternal anymore.
