Wayfinding Failure in a Single-Corridor Clinic
An outpatient clinic has a single 60 m straight corridor. The entrance is at the south end. Registration is 18 m along the corridor but set 4 m back in a side bay, so it is not visible from the door. The main waiting area is 24 m ahead on the right; the lift core is at the far north end. Consultation rooms open off three side corridors at 30 m, 42 m and 54 m. All doors are the same pale grey, there are no exterior windows, and the only signs are small room-number plates. Staff report that patients queue at the lifts even for ground-floor services, miss registration, and ask directions at the 30 m junction. The clinic wants a low-cost retrofit, not a new plan.
1. Diagnose the two strongest spatial causes of the wayfinding failures. Use the evidence in the setup.

The first cause is the registration bay: it is 18 m in but set 4 m off-axis, so from the entrance a patient sees the corridor and the far lift core, not the desk. That makes the lift the default visual destination. The second is the 30 m junction: three side corridors meet a 60 m tunnel with identical grey doors and no exterior view, so there is no landmark at the decision point. The queue at the lifts is therefore not a lift-capacity problem; it is a visibility problem. The missed registration and repeated questions are symptoms of the same failure: decisions are made where information is absent.
2. Propose a retrofit package under a modest budget and predict which symptom each item addresses.

Open the registration bay to the corridor and turn the desk to face the entrance, so it is visible from the door. Put a staffed information/nurse point at the 30 m junction, not a signboard, because a person is a stronger landmark. Use a continuous floor colour band from the entrance to the main waiting area, then branch bands to the three clinic corridors; name destinations ('Dressing', 'Orthopaedics') rather than room numbers. At the lift, add a floor-level sign: 'Lift to floors 1–3; ground-floor clinics straight ahead'. This addresses registration, junction hesitation and lift queuing respectively.
3. A vendor proposes 40 new overhead signs. Evaluate this proposal.

Forty overhead signs would probably make the ceiling noisy and still fail at the 30 m junction, because signs do not create a memorable structure. Wayfinding works best when the route is simple, the destination is visible, and decision points are marked once with a clear name. Use a small number of signs at the entrance, the 30 m junction and the lift, and spend the rest on opening the registration desk and adding the staffed junction point. Evaluate after two weeks by counting directions requests and lift use for ground-floor clinics.
