In Copenhagen’s Nordhavn neighbourhood, a post-industrial area that is being transformed into a new district, architects COBE have turned an old 17-storey grain silo into an apartment block. The result is a monolithic building with a fantastic concrete interior left over from its old life as an industrial storage space. The facade is made of raw, galvanised steel, which acts as a climate screen and makes the building suitable for flats. There are 38 apartments in The Silo, some with ceiling heights of up to seven metres (23 feet), and the building really shows how urban planning can be an opportunity to reuse and reform existing spaces. There’s also a restaurant in the Silo, which can be visited by non-residents.
