Distinguished by its wedge-shaped form, green slopes and blocky façade composed of aluminum bricks, CopenHill is built from the idea of using an industrial space for recreational purposes: “BIG came up with the idea of using the roof to satisfy a need that many Danes have—to be able to ski, climb and hike all year round, to feel the novelty of a mountain in an otherwise flat country”, notes Christian Ingels, CEO of CopenHill.
