Designing public playgrounds for inclusion: a scoping review of grey literature guidelines for Universal Design

Universal Design (UD) is promoted internationally for the design of public playgrounds that support outdoor play, social participation, and inclusion. Despite this international recognition of UD, there is a lack of research evidence concerning the applicability of UD for playground design. Instead, municipalities need to rely on best practice guidelines to inform the design of public playgrounds for inclusion. Internationally, numerous grey literature guidelines have been produced for designing public playgrounds for inclusion, resulting in a lack of consensus on core principles for applying UD. Thus, this scoping review study aimed to synthesise findings from a review of international grey literature guidelines to strengthen the knowledgebase for designing public playgrounds for inclusion. Three themes were identified that characterise core considerations for good design: (1) design approaches, (2) design principles and (3) design recommendations. Although UD is recognised as having potential to support the design of public playgrounds, inconsistent design approaches, principles, and recommendations, were communicated within these guideline documents. Still, the core concept of inclusion underpinned all guideline documents and a tailored application of UD dominated. Consequently, to fully realise the design of public playgrounds for inclusion, UD may need to be tailored for play; however, further research is required.
