There is a need for spaces that can support reflecting on and reimagining design, and redirecting it toward sustainment and justice. Such spaces would necessarily operate with the understanding that design is ontological and has political consequences. We might think of such spaces as metabolic design museums. In this paper, we imagine how metabolic museums might help to redesign design through keeping process at their heart and critically unpacking design’s involvement in urgencies as well as possibilities to envision and move towards more just futures. To do this, we build on intersectional feminist analysis of existing design museums through museum visits and participatory workshops, as well as inspiration from activist spaces; and we speculate about how feminist tactics applied by para-museums could catalyze transformational processes. If those processes were successful, a design museum would then enter into a state of continuous metabolization and become able to contribute to transforming design.
