The vision for Hotel Alsik was to create a design that represents the city’s long history and ongoing growth. Among the weathered brick and pastel storefronts of Sønderborg’s cobbled streets, Hotel Alsik offers a contemporary architectural interpretation of the extant urban fabric. An abstracted brick motif weaves its way up the hotel’s aluminum and glass façade – where traditional building material meets its modern reimagining.

The building is broadly divided in two; the taller tower element containing primarily hotel and restaurant program, and the lower volume housing spa facilities. The 190 hotel rooms follow a simple, regular module, with each room boasting views onto the water, promenade, or city. Three restaurants (Alsik, Freia, and Syttende) are arrayed throughout the building, with the fine dining restaurant Syttende boasting panoramic views from its placement on the 17th floor. From the 16th floor, visitors can see out across Sønderborg, the Flensburg Fjord and, on clear days, its rumored, even to northern Germany.

Alisk is both part of the city’s Project Zero vision and a demonstration venue for clean-tech expertise in the Sønderborg area. The building is currently 76% carbon neutral – the result of a numerous sustainable strategies and technologies at work. Photovoltaic cells on the roof generate 35% of the hotel’s energy and the heat supply is met entirely by green district heating. Additionally, the building operates with the aim of reducing waste, using local and organic suppliers, and reusing materials where possible.
