Parks and public baths answer through open space and water, while plazas create room for the looser activity of being among other people. They give unclaimed time a permanent location and allow rest to become a shared urban experience. Rest occupies the same ground as play, which thus gives an underused piece of public housing landscape a broader social role. Permanent leisure architecture requires more than a persuasive installation. The right to rest is built through architecture, then sustained by the rules that govern who may occupy it and for how long.
