The revival of an iconic building.

At the crossroads of the bustling city of Brussels and the neighbouring Sonian Forest, you find La Royale Belge.


A treasured building located in the exceptional green setting of an 8 hectare park. Eager to embark on a new adventure in hospitality.

True Belgian craftsmanship.

A masterpiece of architecture and imagination.

Once designed by functionalists René Stapels and Pierre Dufau, yet thoughtfully done over, the building of La Royale Belge plays with volume, materials and light.


New objects, designs and other castles in the sky are now meticulously created by DDS+, Lionel Jadot and Zaventem Ateliers.
