The conversion of the Frøsilos, Copenhagen fits into this categorisation but represents an even more radical design. Whereas a warehouse is a more or less complete structure, which requires modest adaptation to allow it to function as housing without losing its original charm, silos are different: they are very basic and bare structures, they are incomplete. This bareness and incompleteness comprise the challenge of this project.

The structural limitations of the silo hold the solution to the design. For instance, big openings are difficult to make in the exterior concrete rings. Making door openings is possible but complicated, and can only be done in a limited number of locations. Locating apartments in the silos might imply, in areas where views are available, that the spaces are directed inward. For a warehouse renovation this might be acceptable, due to its monumental status, but in the case of a silo, this type of design misses a key opportunity. In addition, if you were to fill the silo with floor slabs and walls, it would destroy the most exciting aspect of its present state: its emptiness.
