Reuse to Reduce: Architecture within a Carbon Budget. The Case of BioPartner 5 - Popma ter Steege Architects documents the building of BioPartner 5 at Leiden Bio Science Park, the first Paris Proof, demountable building in the Netherlands designed by Popma ter Steege Architechten. Unable to ignore the pressing challenges our world faces, the architects developed ideas for a circular building, finding ways to reduce the consumptions of raw materials, energy, and water. They dismantled and reused steel from the base of another nearby university building, repurposing 165,000kg of steel for the skeleton of the new building. From the steel structure to the internal walls, the floor finish to the toilets, this project shows the promising future of sustainable architecture.
