Construction of new volumes and open areas within the existing station caps in the Gare Maritime.

The building
The station consists of 7 station caps that date from the beginning of the 20 st century: 3 main former train aisles with a wingspan of 26 meters and 4 lower former platform hallls. The whole is made of iron, cast iron and glass. The pillars have Art Nouveau curls, the wooden roof rests on elegant arches.

The halls are 280 meters deep and 140 meters wide. The peaks of the roof are 23 meters high.

The project
By the installment of 12 separate building blocks with a footprint of 1,450 square meters and 4 floors, 34.000 square meters will be added to the 39,000 square meter area of the station hall.

On the ground floor there will be shops, showrooms and catering establishments, offices will be housed on the upper floors.

"We see it as a new contemporary neighborhood," says Willem-Jan Neutelings to the newspaper De Standaard. "We keep the three middle covers empty, in the lower halls we create green gardens over the entire length." In the side halls, six transverse streets will be constructed. The whole has to exhale the atmosphere of the Spanish Ramblas. 


  • In the side halls there is built with Cross Laminated Timber. A first for Belgium on this scale. 
  • Advice atypical fire connections and fire penetrations CLT
  • Architecturally correct connection of valuable patrimony and new construction. 
  • Optimization of the implementation method. 
  • Appointment of executors 

An important challenge was the correct implantation of the new building volumes in relation to the steel structure of the existing halls. To analyze the geometry of these existing steel constructions, a 3D point cloud was created using laser scans.

An equally big challenge was the modeling of the wooden joinery in the new volumes. The BIM models architecture and stability were used to view all connections of different elements in 3D and to assess the finer points of the proposed construction details.
