Office Signage and Wayfinding: Helping People Find Their Way
Wayfinding is the planned system that lets someone move through a building without asking for directions. It works by placing information at the points where people must choose, in a consistent hierarchy — and it fails when signage is treated as decoration added after the fit-out is complete.

Wayfinding starts with routes, not walls
The common approach is to complete a fit-out, notice people getting lost, and add signs where they hesitate.
The designed approach is to walk the routes first:
- A visitor arriving at the building entrance, reaching reception, then a meeting room, then finding the toilets
- A new employee finding their desk, the pantry, the fire exits, the meeting rooms
- A delivery reaching the correct door without crossing the visitor route
At every point where one of those journeys requires a choice, information is needed. Between those points, it is not.
The hierarchy
| Level | Answers | Placed at |
|---|---|---|
| Primary | Which floor, which zone? | Lift lobbies, main entrances |
| Secondary | Which way from here? | Route junctions, corridor decisions |
| Tertiary | What is this room? | At each door or room |
| Statutory | Where is the exit? | As required, independent of the above |
Keeping the levels distinct is what makes a system readable. A sign trying to serve two levels at once usually serves neither.
Statutory signage is not a design decision
Exit signs, escape route marking, assembly points and safety notices are requirements. Their positions, sizes, visibility and illumination — including behaviour during a power failure — are governed by the applicable rules for the building.
What applies to a specific project is determined under NBC 2016, Part 4 and local requirements by the fire consultant and the authority having jurisdiction. Fire safety signs are addressed in IS 12349, with graphical symbols in ISO 7010.
The practical design point: statutory signage must not compete visually with wayfinding or branding. If a bold feature sign draws attention away from an exit sign, the design has created a hazard.
Why it belongs in the design, not the snag list
Signage needs things that have to exist before the walls are finished:
- Power for illuminated signs, without surface cabling
- Fixings suited to the construction behind — glass, plasterboard, stone and timber all differ
- Lighting coordination, so signs are legible rather than in shadow, with interior illumination practice in IS 3646
- Wall finishes that the sign can sit on cleanly
- Space, so a sign is not competing with a switch plate or a fire panel
Every one of those is straightforward at design stage and awkward afterwards.
Materials and durability
Signs live at hand height on routes people use daily:
- Edges and corners get knocked
- Surfaces get touched and cleaned repeatedly
- Applied vinyl lifts at the edges over time
- Sunlit positions fade
Specify for that, and keep the system extensible — a floor will be reconfigured, rooms will be renamed, and a signage system that cannot absorb change gets replaced piecemeal with mismatched items.
Room numbering
Adopt a logical scheme at the outset — floor, zone, sequence — record it, and leave gaps for future rooms. Numbering invented during the fit-out produces a building nobody can navigate and a facilities record nobody can use.

Statutory signage requirements for a specific building must be determined by the project's fire consultant and the authority having jurisdiction.
