The Decolonising Design Group relocates design from universal problem-solving to the politics of world-making. Its iconic concept is pluriversality: design cannot responsibly operate from a single modern, Eurocentric ontology while treating alternative epistemologies as contextual variations around a universal centre. The roundtable’s form is itself methodological, threading distinct positions across Indigenous knowledge, capitalism, pedagogy, materiality, mobility, language, gender and coloniality without resolving them into one doctrine. This produces a conceptual operation of disciplined non-unification: difference remains generative because each intervention modifies the field of the preceding one. Design becomes accountable for the worlds, exclusions and subject positions it helps reproduce. Its wider bridge reaches decolonial theory, STS and critical pedagogy, where knowledge is understood as situated and infrastructural rather than neutral, and where the legitimacy of a method depends partly on whether it can encounter other knowledge systems without absorbing them into its own categories.
