Hack Our Play (HOP) is Singapore’s first participatory, community-built play space. It is an initiative that lets children, educators, and parents co-create their very own play space, from start to finish. Together, they will be able to conceive, create and curate a safe and unique play experience while also fostering stronger bonds, greater community investment and a sense of pride and excitement through the process. This toolkit offers a starting point, source of inspiration and how-to guide, for those who are looking to co-create their very own community-built play space in preschools or at under-utilised public spaces.
