At the edge of the Northern Harbour of Copenhagen, this contemporary office building, known as Unionkul, cuts a striking silhouette.

The project was completed in 2015 and occupies a temporary site on a vacant lot that is earmarked for future residential development.

Consisting of an impressive stack of repurposed containers, the 660 square metre structure is an office building made to be moved.


Designed with energy efficiency in mind, the project is an innovative experiment in pre-fabricated architecture that challenges universal waste issues and traditional building techniques.


The used containers have been left almost untouched. Pre-existing scuffs, dents and imperfections have been preserved and all functioning doors, original floors and corrugated surfaces are intact.

The only modification is a grey matte coating, which ties together the overall look and feel of the building.
