For buildings that hold flats, shops and offices on the same block. Zoned access, time-bounded passes, and one audit trail across all three populations.
"At 7:30 the office floors open to staff lifts only. At 9:00 the retail concourse opens to the public. The residential lobby is its own door, all day. The same building. The same identity model. The same logged record at the end of it."
Residential, office, retail and service zones each carry their own rules. A retail courier doesn't see a residential lift. A tenant employee doesn't ride into the flats.
Office reception, residential lobby, retail loading bay — same identity model, separate desks, separate hours, one log.
Office tenants manage their own employees. New starters appear at the desk on day one, leavers vanish at five p.m. on their last. Each tenant sees only its own people.
Inbound deliveries route to a single loading bay with a window. Retail unload, residential parcels and office mail — sorted, signed, photographed.
A weekend launch is a time-window: pre-approved staff, a guest list, a pass that expires on its own. The building doesn't have to remember.
A retail-only fire test, a tower-wide drill, an after-hours office lockdown — push the right notice to the right population, with read-receipts.
