The Exhibition Layout With a Fixed Skeleton
A designer is laying out a 200 m² temporary exhibition in a rectangular hall with one entrance and one emergency exit at the far corner. The brief lists 6 themes that 'should flow logically.' The hall has two structural columns 4 m from the long walls, splitting the space into a central zone and two side aisles. Fire regulations require a 1.5 m clear route from any point to the emergency exit. The client wants visitors to 'experience the themes in order,' but visitor research from similar shows says most people drift toward the brightest, most open area first. The budget covers 12 display units and 4 text panels.
1. How should the designer reconcile the client's 'themes in order' wish with the observed drift toward open, bright space?

The two are reconcilable if the designer treats circulation as the sequencing device rather than relying on visitors to follow numbered zones. If people drift to the brightest, most open area first, the designer should make that area the intended first theme, not fight the behaviour.
Concretely:
- Place Theme 1 in the open, bright central zone near the entrance so the natural drift lands on the correct start.
- Use the two side aisles (behind the columns) for later themes, so progression is a loop that returns visitors toward the exit.
- Use sightlines and lighting gradients to pull people from the bright start into the dimmer, more enclosed later zones - light becomes the sequencing cue.
The client's 'in order' intent is preserved; the mechanism changes from asking visitors to follow order to designing the space so the natural path is the intended order. That is the core layout judgement: work with observed behaviour, not against it.
2. Given the 1.5 m clear-route rule, the single far-corner exit, and only 12 display units, how should the designer place units and check the plan?

The 1.5 m clear route is a hard constraint that governs everything else, because the exit is in the far corner and every visitor must be able to reach it from anywhere.
Approach:
- Draw the clear route first, before placing any unit: a continuous 1.5 m-wide path from the entrance, through the central zone, around the columns, to the far-corner exit. Treat it as a no-build corridor.
- Place the 12 units against or beside the route, not in it - using the side aisles and wall lines so displays frame the path without narrowing it. Columns can become display anchors, which uses the awkward structure productively.
- Check pinch points: at the columns, the gap between column and wall must still leave 1.5 m clear on at least one side; if the column sits 4 m from the wall, the aisle is generous and a unit can sit against the wall leaving the route intact.
- Verify the worst case - a visitor at the far end of a side aisle must have an unobstructed 1.5 m path to the exit, not just the central zone.
The 12-unit budget is comfortable for 200 m²; the discipline is restraint in the route and using the 4 text panels at decision points rather than filling space. The plan should be checked by tracing the exit route from every corner before sign-off.
