Royale Belge

Brussels, Belgium 2019 – 2023

Client: Souverain 25 European Heritage Europa Nostra Award

This commission was won in a competition organised by the City of Brussels. The design is a collaboration with Antwerp-based Bovenbouw Architectuur and was developed in partnership with Brussels-based DDS+ architects.

Located in the south-east of Brussels, in a landscape of lakes and beech trees, the Royale Belge building is a fine example of 1960s corporate architecture. Designed by the renowned Belgian architect René Stapels in collaboration with architect Pierre Dufau, the building was completed in 1970 as the headquarters of the Royale Belge insurance company. Its cross-shaped tower and large two-storey podium contained offices, conference and training facilities for around a thousand of the company’s staff. A landmark in Brussels’ architectural landscape, both the 80,000 m2 building and its surrounding landscape received regional heritage protection in 2019.
