Sweco has signed an agreement to acquire CONIX RDBM Architects with offices in Brussels and Antwerp in Belgium. The acquisition will strengthen Sweco’s position in large-scale sustainable urban development through the addition of some 50 experts.

The acquired company CONIX RDBM Architects delivers architecture, interior design and master planning projects across sectors including offices, residential, education, healthcare and mixed-use developments. The company’s turnover was approximately EUR 7.6 million in 2025, and its Belgian activities are expected to be consolidated into Sweco from 30 April 2026.

“It is with great excitement I welcome CONIX RDBM Architects to Sweco. This architectural firm has left its mark with high quality projects that combine contemporary design with impressive sustainability performance. Together, we will offer advice to public and private sector clients, covering the entire lifecycle of urban transformation,” says Erwin Malcorps, Business Area President of Sweco Belgium.

Sweco and CONIX RDBM Architects have previously been involved in joint client projects. One example is the award-winning Herman Teirlinck building in Brussels, a major project commissioned by the Flemish government, using digital twin technology to optimise sustainability performance.

“The addition of CONIX RDBM Architects means Sweco is now even better positioned in Belgium, where substantial public and private sector investments are being directed toward sustainable urban development. Market demand is being driven by national regulatory requirements and reinforced by EU climate and urban policy frameworks – accelerating the transition to low-carbon, resilient cities,” says Erwin Malcorps.
