The construction of the future spa hotel and office complex in Aarhus is one of the most ambitious projects in the district. With approx. 342 rooms, several spa floors and around 16,000 m² of office space, the project combines architectural ambition with technical complexity. 
As a subcontractor on the aerated concrete contract, AROS Development has been a key player in the project's internal structures, where around 7,000 m² of AAC walls are being installed – from basement level to the top floors. 
"It's a fantastic project to be part of – both in terms of scope and complexity. We are working at heights rarely seen in other construction projects, and at the same time, the hotel's spa areas and the many technical solutions place high demands on precision. It is precisely these kinds of tasks that make it exciting to be in this industry," says Camilla Taulbjerg Poulsen, Contract Manager at AROS Development. 

When Technology, Form and Materials come together 

The upper floors in particular – including the spa areas – have required advanced solutions, including extensive use of curved aerated concrete blocks in various radii. AROS Development carried out the installation, while Xella supplied large quantities of aerated concrete in close coordination with both the subcontractor and the main contractor NCC. 
Deliveries have been spread over a long period and have required both flexibility and precision, as the work is being carried out in parallel on many floors and under changing schedules. The hotel's construction with curved walls and special solutions makes the project unusual – also from a material supplier's perspective.
"The construction project in Aarhus is one where our solutions really come into their own. The combination of height, constructional complexity and the desire for precise, versatile autoclaved aerated concrete solutions places high demands on both materials and collaboration. We are proud to contribute to a construction project that stands out – both in scale and in architectural ambition," explains Normann G. Karlsen, Sales Director at Xella Denmark. 

Logistics, Height and Special Work Processes 

Working on a 20-storey building places unique demands on logistics, safety and daily planning. As the main contractor, NCC has maintained a strong focus on safety and ongoing adjustment of schedules throughout the project, particularly in connection with the complex spa floors. 
For AROS Development, the project has been a textbook example of collaboration, with both suppliers and contractors supporting each other through long planning processes and great technical care. 
"This construction project requires everyone to think about logistics and safety every single day. When you're working at such heights and across so many floors, everything has to work. That's why strong partnerships are so important – both with the main contractor and with suppliers like Xella, where we've always had clear and reassuring communication and where we feel heard and understood," concludes Camilla Taulbjerg Poulsen.
