The Alsik Hotel and Spa was the first phase of the redevelopment of Sonderborg’s waterfront. Led by the Claussen family, who own Danfoss, it was offered to the people of Sonderborg but was also created to put Sonderborg firmly on the map as a destination in Denmark and neighboring countries.


We created a spa concept reflecting the beauty and creativity of the intelligent and functional design culture that Denmark and Scandinavia are famous for. We balanced high tech with high touch, dedicated a floor to each and created spaces for all age groups to touch on and enjoy wellness and wellbeing. And we designed a unique room, the Danam – a play on a Danish Hammam experience.


Alsik arranged for an open day during construction, which saw thousands of locals walking through a building site and pre-booking memberships. Most memberships were sold out before the pre-opening and it has been growing in strength since.
