Swedish engineering consultancy Sweco has signed an agreement to acquire CONIX RDBM Architects with offices in Brussels and Antwerp in Belgium, according to Cision.

The Stockholm-headquartered company strengthens its position in large-scale sustainable urban development through the addition of approximately 50 experts.

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 €7.6 million in 2025, and its Belgian activities are expected to be consolidated into Sweco from 30 April 2026.

Erwin Malcorps, business area president of Sweco Belgium, said: "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."

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.

Malcorps added: "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."

The acquisition aligns with Sweco's strategy to grow through adding key skills. The group completed 13 acquisitions in 2025, adding approximately SEK 2.1 billion (€177.24 million) in annual net sales.
