Designed by Semrén & Månsson, the hotel was built in the former Posthuset (post office building) of Gothenburg, with the addition of a modern tower.
The hotel is owned by the Swedish firm Home Properties, which is controlled by the Norwegian billionaire Petter Stordalen.
Posthuset was designed by Ernst Torulf and was completed in May 1925.
In 1995 it was registered as a listed building, meaning that the facade and certain prominent features, for example kassahallen (the cash hall) could not be altered.
