CONQ explores local, biobased, and circular construction methods, aiming to bridge the gap between demonstration and implementation. The goal of the project was to develop a functional, versatile biobased cladding system, which utilizes calcareous waste shell material. Advancing sustainable architecture for the future, while challenging the aesthetics of regenerative building materials.

Heidi Jalkh and Angie Dub, the team behind this Experimental Fellowship with Bauhaus Earth project, bring together the expertise of a materials designer and an environmental architect. Jalkh and Dub synthesize design and science, conceiving of their collaborative work as both artistic practice and research laboratory. They root their methods in local contexts, with the potential to be replicated in diverse settings; reimagining the future of the built environment through innovative methods and technologies.

Ceramic materials make up a significant proportion of the cladding materials used in construction, including clay, bricks, tiles, glass, and cement. While ceramic processes are known to be energy intensive, they could be sustainable if maintained over time. However, due to the high rates of demolition and reconstruction in urban areas, ceramic materials tend to become non-renewable waste.
CONQ takes inspiration from nature to achieve maximum performance while using limited resources. It explores the potential of mineralised biogenic materials, such as shells and eggshells, to provide a sustainable alternative to cladding systems by transforming waste into a bioceramic at ambient temperature.
