“…Moreover, the requested qualities in green spaces often include variation as a quality in its own right [33,46,53]. This can be seen in qualities from a mixture of open and closed spaces [46], cover both highly designed and maintained playgrounds with smooth slopes and surfaces [52] and age-appropriate size and design [62,64,69,81], adapted to all variations of ability [44,72], to informal and unprogrammed areas [24,45,59,60] that are green, natural or wild [13,14,45,50]. The qualities needed in different types of spaces may also depend on the context; while some studies advocate for the elimination of architectural barriers more generally [53,56], others frame a selective reduction or application around specific types of spaces [27,44] where, for example, entry gates and fences can be used as a feature for controlling access (as connected to theme of access) [28].…”
