Although stress relief comes in many forms, soaking in a swanky sauna hanging over the water may just be the new trend in spa design. Danish firm Arcgency has converted a former coal crane into The Krane, a multi-tiered structure topped with a soothing spa retreat that overlooks Copenhagen’s industrial harbor.


The Krane space was carved out of a former coal crane that has sat overlooking Nordhavn’s industrial port for years. The creative adaptive reuse project was a collaboration between owner Klaus Kastbjerg and architect Mads Møller from Arcgency, who wanted to convert the old crane into a useful space for the city.

The first floor of the crane was converted into a glass-enclosed meeting space called the Glass Box. A calming spa and wraparound terrace are on located on the second floor, and on the top floor, guests can enjoy a calming lounge space and additional terrace that looks out over the water.

Paying homage to the crane’s industrial history, the structure was clad entirely in a stark black, on the interior as well as the exterior. The monochromatic color scheme was used to reduce distractions, intentionally putting the sole focus on the beautiful 360-degree views of the harbor.

The space was decorated with minimal furnishings made out of leather, wood, stone and steel – most of which were custom built so they could disappear into wall panels. Local artists were commissioned to create various pieces, which are also subtly embedded into the walls.

Møller explains that the monochromatic color scheme was inspired by the crane’s new use as a soothing getaway, “It’s all part of the vision, where the focus has been the integration of sensations—sight, sound and stemning (the Danish word for atmosphere). The Krane involved a 360-degree inside-outside approach. Natural light directly affects how we feel in a space and our happiness overall. So we optimized the inside to capture natural daylight and set the stage for the views of the water outside.”
