Architectural Alchemy: Translations of the non-human Part 2 Dissertation 2025 Catherine Cousins Ulster University | UK This dissertation investigates the architectural potential of seaweed as a sustainable biomaterial, exploring its application through traditional and experimental methods within a culturally and ecologically responsive framework. It positions seaweed not merely as a construction resource but as an active material with agency, capable of shaping architectural outcomes in dialogue with ecological and cultural narratives. Grounded in material agency theory and supported by practical experimentation in the “Seaweed Lab,” this research adapts techniques such as weaving, knitting, and sewing to develop biodegradable, weather-resistant seaweed panels suitable for cladding and insulation. By situating the study in Northern Ireland, it revives vernacular knowledge while proposing innovative, scalable biomaterial applications that align with contemporary sustainability goals. Ultimately, this work redefines the architect’s role as a translator of non-human materials, advocating for architecture that embraces natural cycles and fosters a circular economy. The dissertation contributes original insights to biomaterial research and encourages a more inclusive, accessible approach to sustainable building, positioning seaweed as a viable and culturally meaningful alternative within the pursuit of net-zero architecture.
