This chapter distils design lessons from post-occupancy observation across PRH estates. It shows how modest, repeatable moves—continuous shade and rain cover, bench-niche sequences, curb radii that calm rather than forbid, all-weather queue lines, parcel-shelf nooks, stroller-and-trolley bays, and barrier-free cross-blocks—compound into measurable comfort and reliability for households on tight schedules. Ground-floor “switchable” rooms (service ↔ community use), plug-in points for licensed evening vendors, school-gate porches, and quiet decks off lift lobbies are presented as a kit-of-parts that respects operations and budgets. Thermal spot checks, path-reliability traces, and simple crowding indices guide prioritisation. The argument is pragmatic: PRH works best when designed for the day—peak flows, predictable waits, and safe edges—so that care work, commuting, and small commerce interlock with minimal friction. Retrofit sketches and cost bands close the chapter to support near-term upgrades.
