The project takes place in a former 1200 square meter antiatomic shelter. An amazing location 30 meters down under the granite rocks of the Vita Berg Park in Stockholm. The client is an internet provider and the rock shelter hosts server halls and offices. The starting point of the project was to consider the rock as a living organism. The humans try to acclimate themselves to this foreign world and bring the ‘best’ elements from earth: light, plants, water and technology. We created strong contrasts between rooms where the rock dominates and where the human being is a stranger against rooms where the human being took over totally. The choice of lightning has been very challenging. We tried to bring as much variation as possible. Otherwise it is very easy to loose the feeling of time in an enclosed space. Our references come straight from science fiction films, mostly ‘Silent Running’ and a bunch of Bond films with Ken Adams set design.
