The complex of 100 metres, the equivalent of approximately 30 stories, will include a hotel, offices and possibly housing. The building will be equipped with an entrance to a new station at street level directly opposite the city's old main railway station, Centralen, and will therefore be a landmark for Stockholm's new metro.

C.F. Møller's design is based on a concept of multi-function, a building where many varying uses can take place simultaneously.

The tower draws inspiration from the city of Stockholm, an example of which is Stockholm's largest church Klara kyrka situated right next to the site. The project reinterprets the city's beautiful town hall and classic church steeples, which combined make up the city's historic landmarks and create Stockholm's historic skyline, but at the same time integrates the unique urban feeling defining the area around Centralstationen.
