Sweet Terrain
Bahbak and Rafael will present their project, Sweet Terrain, which repurposes wild London clay excavated during HS2 railway construction in West London into a system of wall tiles for the proposed Old Oak Common Station. The project reimagines this overlooked material as a new architectural language rooted in the area’s cultural and industrial heritage.
Bahbak and Rafael collaborated with local Middle Eastern bakers—drawing on their tools, aesthetics, and craftsmanship traditionally used in making maamoul cookies. Carved wooden moulds, typically used to shape pastry, were instead pressed into clay to imprint intricate patterns onto the tiles.
To bring the tiles into public use, the team partnered with Craven Dunnill Jackfield—the UK’s last remaining Victorian ceramic tile manufacturer, known for producing many of the London Underground’s historic tiles.
The result is a system of hyper-local tiles that connect people, place, and process—supporting sustainable practice and British industry, while giving new form to the materials and stories embedded in West London’s evolving landscape.
