Sweco has signed an agreement to acquire assar architects, a leading architectural practice specialising in large-scale public and private sector projects, including offices and commercial buildings, healthcare, defence, education and urban planning. The acquisition will significantly broaden Sweco’s architecture offering in Belgium and Luxembourg.

The acquired company assar architects focuses on “inclusive architecture” and primarily operates in Belgium and Luxembourg. The company has worked on projects such as the NATO headquarters, some of Belgium’s largest hospitals and developments for European institutions and multinationals.

This acquisition will strengthen Sweco’s organisation through the addition of approximately 150 experts and the company is being consolidated into Sweco immediately. The turnover of assar architects was approximately EUR 16.5 million in 2024.

“I warmly welcome assar architects and their inclusion as a new and important part of Sweco, the European leader in architecture and engineering consulting. We have collaborated successfully on client projects in healthcare, government and defence as well as on complex urban development projects subject to stringent sustainability standards. Together we will be ideally positioned to deliver maximum client value in the ongoing green transition and modernisation of the built environment in our regions,” says Erwin Malcorps, Business Area President of Sweco in Belgium.

Belgium and Luxembourg are transitioning toward sustainable, energy-efficient and smart urban development phases with a focus on infrastructure renewal, digital innovation and climate goals, and which are strongly supported by EU programs like the Green Deal, NextGenerationEU and Horizon Europe.

Sweco holds a strong market position in Belgium by combining engineering and architecture consulting to create synergies for public and private clients. In 2023, Sweco acquired VK architects+engineers, adding 600 experts to Sweco. With the new addition of assar architects, Sweco further solidifies its position in Belgium.
