To acknowledge and honour the heritage value of the residences, innovation extended well beyond the building itself. The project pioneered new approaches to design, procurement and collaboration, engaging four multidisciplinary teams of architects, engineers, contractors and manufacturers in a competitive yet collaborative learning process.

What emerged was much more than a renovation project. A student residence from the 1970s became, all at once, a research platform, a full-scale design testbed, a showcase for circular construction, and an award-winning design. The project demonstrated that energy performance, affordability, sustainability and heritage conservation need not compete with one another, but can reinforce each other when approached through a life-cycle perspective.

Key insights

  1. Like the Circular Retrofit Lab, this living lab focuses on the iconic student residences designed by Belgian modernist architect Willy Van Der Meeren in the early 1970s. Yet this time, its heritage values take centre stage. [vubwejv405...405.axc.nl], [archdaily.com]
  2. The project evaluates solutions through four lenses: energy, heritage, sustainability and affordability. Here, leaving the concrete exposed, integrating reversible window frames, and preserving existing elements are not compromises, but circular synergies.
  3. Rather than developing a single renovation solution, the project showcases three scalable strategies for practitioners facing similar challenges across Brussels. Each strategy serves as a provoking discussion starter. [vubwejv405...405.axc.nl], [makerarchitecten.com]
  4. The realised project demonstrates extensive material reuse while combining heritage preservation with contemporary comfort and performance requirements. Its visual quality and aesthetics complete the story. [archdaily.com], [vub.be]

Project context

The WVDM Living Lab investigates sustainable renovation strategies for post-war heritage buildings as in the whole Brussels Capital Region, as was therefore funded through the Innoviris Living Labs Test-It programme, with support from the European Regional Development Fund and the Brussels-Capital Region. The project rand from 2017 to 2021, with the construction delivered in 2023.

VUB researchers, infrastructure services, architects, engineers, sustainability experts, construction companies and regional innovation actors partnered-up, including MAKER architecten, Origin, VK, VITO and Beneens for the final realisation.

The WVDM Living Lab ultimately proved that preserving a building does not mean freezing it in time. Instead, it showed how existing buildings can continue to evolve — adapting to new needs while retaining the character, stories and materials that make them worth keeping in the first place.
