Project Support I Collaboration

Construction of an 80 m high residential tower on the Nieuw Zuid site in Antwerp. The tower has 25 floors and is flanked by 6-storey buildings. The residential tower is a hybrid apartment building with a core of steel and concrete surrounded by a wooden frame.

This residential tower is the first wooden skyscraper in Belgium.


  • Concrete frame (beams, columns) with prefabricated wooden facade.
  • the study and examination of the specific façade construction,
  • Slabs composed of timber and concrete, executed as a hybrid construction.
  • Ventilation ducts are integrated in the slabs.
  • The wood remains exposed as a wooden ceiling.
  • Wooden facade-cladding.

The biggest technical challenge lies in bringing the wooden facade unusual for high-rise buildings in line with the fire legislation.


Bureau Bouwtechniek modeled the BIM model architecture, excluding the layout of the apartments and office areas. The BIM model stability was prepared by stability bureau Greisch, the BIM model techniques by Sweco. To ensure smooth model coordination between the study offices, the aspect models were exchanged regularly.

For Bureau Bouwtechniek, the challenge of elaborating the 1st wooden tower in Belgium in BIM lay in organizing and structuring the extensive library of elements that would shape the outer shell and its accessories. Shigeru Ban's particular focus on modeling and specific façade design resulted in the need to develop geometry and associated data one-to-one.

The gross floor area of the project is 35,000 m² and 22,500 elements were measured from the aspect model architecture.
