As part of the 2022 London Design Festival, this bespoke architectural installation uses an ancient-Egyptian wall-building technique to showcase the cutting-edge carbon-neutral concrete that’s been developed by the London-based enterprise Seratech. Their team – a spin-out from Imperial College London – has developed a way of sequestering CO2 within the creation of novel, waste-free construction materials. The installation is engineered by AKT II, and has been delivered for the 2022 festival with the support of the specialist concrete contractor Byrne Bros.
