Copenhagen is filled with architecture that takes risks to defy the traditional definition of a building. Aside from 8House talked about earlier, Bjarke Ingel and his team have built other innovative residential buildings such as the VM Mountain, VM Houses, and Dortheavej.  CopenHill, also known as Amager Bakke, is a Copenhagen-based heat and waste-to-power plant designed by the Bjarke Ingels Group and built in 2017. What is striking is that this industrial plant doubles as a ski slope as its roofline is designed to engage with the community, relating the value that a “sustainable city is not only better for the environment — it is also more enjoyable for the lives of its citizens.”
