Avenue de l’Héliport, in the heart of the Nord quarter, has been the focus of many projects and surveys. Here, we especially find buildings now occupied by the Brussels Region’s SIAMU offices. The buildings are fine examples of brutalist 1970s architecture: the Brussels Region would like to explore their potential within its programme. In view of their strategic position, in different sectors of the Nord territory (Manhattan district, near the canal, Masui district), the site’s transition from the current SIAMU is particularly important to the future of a territory which is much wider than the site itself.

The survey seeks to assist with the Brussels-Capital Region’s decision-making, in both strategic and operational terms, on what will become of the buildings and how their future transformation will be organised.

The mission includes the following phases:

  • Phase 1: Inventory, analysis and identification of existing and projected potentials;
  • Phase 2: Establishment of scenarios and assessment;
  • Phase 3: Establishment of final scenarios

For this mission, Société d’Aménagement Urbain (SAU) is looking for a multi-disciplinary team of architects-town planners capable of using the project research to view, test, inspect and optimise the challenges and options open for the transition of the SIAMU buildings. Interaction and co-construction with the authorities, including the facilitator Be Sustainable (Réferntiel Quartier Durable in the Region), will constitute a key part of the survey, to obtain an “innovative development model” for the Héliport site’s transition.
