Planning permission has been granted for the renovation and alteration of Royale Belge, a listed former company headquarters in the south of Brussels. The 39,000 sqm office building, built in 1970 and standing within a landscape that is also now listed, has been empty for the last 5 years. The new mixed use programme includes offices, hotel, health club, restaurant and co-working, and is being developed by the consortium Souverain 25.
The project is a design collaboration between CSTJ and Bovenbouw Architectuur, together with local architects DDS+. Construction starts in September 2021 and is due for completion in January 2023.
The commission reflects the practice’s interest in the renovation of existing buildings to address future building needs.
