Resilient communities are an important prerequisite to reach urban resilience. In such communities, citizens need to be able to par- ticipate for improving liveability and safety of their environment. The playable city, where participation is key, provides the environment for this process to unfold. This paper researches requirements for the de- sign of playgrounds: environments for open interaction and collabora- tion, as part of the playable city. Two workshops were organised in two neighbourhoods in The Hague to explore specific citizen preferences for playground design. Neighbourhood locations and the type of informa- tion citizens would like to discover, share, and create are identified, in particular with respect to healthcare, safety and social engagement. The implications of these requirements are presented and discussed with de- sign options which exemplify how playgrounds in the city enable joined information sharing, creation, interaction, and collaboration.

These transitions mandate the ability of individuals and communities to survive despite the challenges with which they are faced [20]. This ability, referred to as urban resilience by the Rockefeller Foundation, is core to their “100 Resilient Cities Network” (100RC). This network helps cities around the world to become more resilient, and ex- plicitly includes social inclusion and cohesion [1] in its goals. As fragmentation of neighbourhoods is one of the major challenges faced by cities [11], this paper focuses on The Hague 1 , one of the 100 RC and the most fragmented city in the Netherlands [12, p. 52]. 1 This paper reports on research performed within the context of the project BART!, that aims to improve coordination and collaboration between citizens, municipality, and police through co-creation, to increase safety and liveability of The Hague.
