Earth-based materials play a central role in JORD’s material strategy. Throughout the design process, their potential was explored through material studies and full-scale testing, including investigations into rammed earth. The design ultimately incorporates unburned clay bricks and clay-based interior finishes, combining low embodied carbon with a distinctive architectural character. Together with timber, hemp, and other biogenic materials, they form part of a broader strategy to reduce reliance on conventional, carbon-intensive construction methods and materials. Unburned clay bricks define the first two storeys of the façade, grounding the building both physically and materially. At street level, they become the primary surfaces encountered by passers-by and users, offering a tactile and visibly natural expression that reveals the material’s origin rather than concealing it.
