Sustainable rebuilding (of the city)

Besides high performance in energy design and circularity, this project approaches prototype circular design principles for sustainable reuse of existing buildings in high-density urban environments.

Circular construction

  • Building in independent layers: elements with different lifespans that can be detached and replaced or recovered without damaging adjacent building parts.
  • Disassembly already foreseen in design. The building as a future materials bank.
  • Materials with low environmental impact and high material efficiency.
  • The new building envelope as green infrastructure for dense urban environments.
  • The envelope is designed as a system of independent layers (Cfr. circular building).
  • Components are accessible from both outside and inside.
  • The new building envelope allows flexible interior design.


We first modelled a BIM model architecture of the existing situation. Using the point cloud and a linked series of 306° photos, the model was adapted to the changes between original building and renovation.

  • The building parts to be demolished were placed in the model with limited detailing and in two demolition phases according to the demolition plans.
  • The new parts were added to the model with a fairly high degree of detailing in order to test in the facade the requested rhythmicity with corner solutions. For the new shed roof above the atrium, it was a challenge to model and correctly measure the sloping volumes in combination with the stability model.

The main building is the converted existing building. A detached new shed was erected next to it. The total gross floor area of all buildings is +/- 14,500 m². 10,879 elements were automatically measured in the BIM model

As executive architects, we help the designing architects with all technical and financial issues so that they can fully focus on the design. We also monitor the implementation and ensure that the objectives and plan are always crystal clear for all partners, so that together we can realise our dreams.

The Scientific and Technical Centre for the Construction Industry (WTCB) recently announced that they will continue under the name Buildwise as an engine of innovation in the construction industry. In addition to the new identity and strategy, they will also move to a new, sustainably renovated office. BOVAArchitects was responsible for designing the sustainable workplace in collaboration with Bureau Bouwtechniek. (dixit Architectura)
