Common ground is a research project focused on the reintegration of Hyper-local clay into our built environment. We partnered with Park royal and HS2 to provide us with large quantities of extracted earth from various London construction sites. The wasted material is collected and then processed into workable clay. This delicate process demanded a thorough research of the possible additives that can be present in the clay and safe firing protocols. However, it also asked us to move away from conventional ceramic techniques to give way to new methods that accommodate for the ambiguous soils of London. The project presents itself as a collaboration between design, science and disturbed soil. Approached with care and naivety, each piece of work lives as a physical hypothesis. We are actively working to bring forward change in the way we relate to the soil we inhabit.
