In 2013, the Kenyan Truth, Justice, and Reconciliation Commission (TJRC) recommended that the former torture chambers at Nyayo House be transformed into a public memorial. The chambers were used under the Moi regime (1978–2002) to torture political dissidents. To date, memorialisation remains deferred amid ongoing state injustices. Working from the specificities of the Kenyan political context, this paper examines the politics of co-design through an intergenerational dialogue and design workshop on Nyayo House, run in Nairobi in 2024. Bringing together survivors and young Kenyans, this workshop was structured in two parts: the morning as a conventional group dialogue and the afternoon as a co-design session for the creation of a memorial at Nyayo House. By examining this workshop through first-hand descriptions and interviews with participants, this paper critically investigates (1) how knowledge transmission diverges between dialogue and architectural co-creation, and (2) what the political effects of such knowledge transmission might be. It engages with Amartya Sen’s deliberative idea of justice, Hannah Arendt’s conception of political innovation, and Achille Mbembe’s philosophy of disenclosure to understand the multiple forms of justice at play. Dialogue appears as a process of augmentation that aids in the implementation of justice as defined through the TJRC, while co-design is found to go beyond extant political relations as a politics of innovation. This recasts justice as a futural practice that opens up new solidarities and imaginaries of justice, situating co-design as a key practice for justice in contexts such as Kenya, where memorialisation can be deployed to enact political closure.
