The Earthen Land Registry Part 2 Project 2021 Daniel Pope Bartlett School of Architecture (UCL) | UK London Clay plays a distinguished role in the rich architectural history of London and has now largely disappeared as a living industry. The Earthen Land Registry, a circular resource system, is proposed, producing new London Clay architectures using emerging technologies and tailored to current environmental sustainability priorities. Clay is sourced from local construction and engineering project waste streams, including the Thames Tideway Tunnel and city super-basements, diverting it from landfill. It is stored in the Greater London area, processed into tailored components including insulative extruded bricks, and used for on-site additive manufacturing. The range of proposals aim to heighten the sensuous and tactile relationship between the body and the materials of our built environment.The ‘Earthen House’ typology has a protective, fired envelope with a long lifespan, and tailored interiors that are 3D printed on-site with clay. The potency of bringing new London Clay systems back to historic London Brick architecture is investigated in the ‘Earthen Blanket’ retrofit strategy, augmenting existing buildings, opening new architectural opportunities, and upgrading performance whilst not compromising the existing building or reducing its lifespan. The proposals are carefully tailored to contribute to London’s migration to net-zero carbon whilst evolving its architecture in the process. Daniel Pope Tutor(s)
