Construction of new facilities on Callens’ own properties in Laakdal and Liège
09 September 2025
Callens is building two new facilities in Belgium: in Laakdal (Kempen) and Awans (Liège). These regions are no strangers to us: for years we’ve been leaving our mark from rented spaces. Successfully so. Now it’s time to shift gears strategically and create room for further growth.
More than 200% growth at each location
Together, the local teams in Kempen and Liège have already handled more than 750 projects, a number that keeps climbing year after year. Revenue followed the same upward trend: in Kempen, it soared by 524% compared to the founding year of 2018, and in Liège it grew by 270% compared to its first year in 2021.
“We’re making a strong statement: Callens is here to stay. Over the past years, we’ve built our project portfolio with enthusiasm and landed some remarkable projects that set the tone. That gave confidence to the businesses established there,” explain CEOs Annick Callens and Windy Moerman.
Focus on sustainability and employee well-being
The new facilities are designed with sustainability and relaxation in mind. That means:
Nearly Zero Energy (NZE) buildings powered entirely by renewable energy
A Calliër Café with bar and training zone
A gym and carwash in Laakdal
The HVAC installation in Laakdal is being designed and installed by Callens itself — a showcase of our expertise. After all, industrial air technology, such as ventilation in production halls, is a core business, accounting for 40% of all activities. The other 60% consists of industrial heating technologies and service.
We aim to move into the new facilities by the end of 2026. It’s a tight deadline, but achievable. Our employees are eagerly looking forward to their new workplace, which will largely mirror the design and amenities of our expanded headquarters in Waregem.
Windy Moerman
CEO Callens Group
Windy Moerman has been Co-CEO of the Callens Group, together with Annick Callens, since 2003. He grew with the company from within: in the early years he, like Annick, worked his way up through every department to acquaint himself with industrial processes and customer needs.
These days, he translates that broad experience into a distinctly strategic and operational role. Under the impetus of Windy and Annick, Callens grew into Belgium’s market leader. Presently, they are purposefully building on an international future for the Callens Group, with steps into the Netherlands and France for starters.
Windy Moerman believes in entrepreneurship with strong, forward-looking partners. He sees the energy transition as a unique opportunity to guide customers to sustainable, future-proof solutions.
The local teams have grown from a small group of ambitious starters into a diverse group of project managers, design engineers, welders, fitters, maintenance technicians, and more, tackling projects of all sizes with a burning passion for progress. To give space to these ambitions, the entire second floor in Laakdal has been left as a shell, ready for future development.
Both sites are already welcoming new colleagues who share the same determination, pride in their work, and team spirit.
