On the 18th of October we will be a guest speaker during the conference “CONCRETE & SUSTAINABILITY. History – Restoration – Perspective” organised by urban.brussels and CIVA. Together with Waldo Galle, from the research group Architectural Engineering (VUB) Stijn Elsen will share experiences on the design and construction of the Circular Retrofit Lab, realised in the former student houses, built by Willy Van der Meeren in the 1970s on the campus of VUB.
