Renovation and re-allocation of D'Ieteren Group's head office on rue du Mail in Saint-Gilles.

With an eye to the future, the D'Ieteren Group decided to diversify its activities and to renovate its headquarters, established since 1906, in a sustainable and multifunctional way for the future. The heritage value of the existing modernist building will be maximised.

One of the architectural objectives is to reduce the density of the site, which covers 67,000 m², and to open up the city block in the image of an international group that is open to the world. The site will include offices, shops and facilities, as well as the D'Ieteren Gallery - while the garage activities have already moved in.


On the Maliestraat, the building consists of two parts: the first volume consists of a skeleton in concrete and steel, the second of Preflex prefabricated pillars and floors in reinforced concrete. 

The lower volume has four levels: ground floor, two underground levels and a parking level accessible via an external ramp. This building houses the technical premises, the showroom, the workshop and the car park. 

The upper volume, which houses the offices, has five storeys and is characterised by:

  • curtain walls made of a series of vertical posts in aluminium  
  • parapets and lintels in green enamelled external panels  
  • a metal structure (skeleton, floors and roof) in the form of a parallelogram resting by means of metal columns on a raised platform that has been laid out as a car park; this terrace forms the roof of the lower volume.
