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

LevelAnswersPlaced at
PrimaryWhich floor, which zone?Lift lobbies, main entrances
SecondaryWhich way from here?Route junctions, corridor decisions
TertiaryWhat is this room?At each door or room
StatutoryWhere 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:

NeedsWhy
PowerFor illuminated signs, without surface cabling
FixingsSuited to the construction behind — glass, plasterboard, stone and timber all differ
Lighting coordinationSo signs are legible rather than in shadow; interior illumination practice is in IS 3646
Wall finishesA surface the sign can sit on cleanly
SpaceSo 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.

Frequently asked

Signage is the physical items. Wayfinding is the system that decides what information appears where, and in what order of importance. A building can be covered in well-made signs and still be confusing, because each was added where someone got lost rather than as part of a plan. Wayfinding starts from the routes people take, not from the walls available.

At decision points — where a route divides, where someone arrives and must orient themselves, and where a destination is reached. Between decision points, signs add clutter without adding information. Walking the actual routes a visitor and a new employee would take, and noting every point where a choice is required, produces a better sign schedule than working from a floor plan.

The order in which information is given. Primary signs handle the building level — floors, main zones, reception. Secondary signs handle directions within a floor. Tertiary signs identify individual rooms. Statutory safety signage sits outside this hierarchy and must never be competing with it for attention. Mixing the levels produces signs that try to say everything and communicate nothing.

It is a requirement rather than a design choice. Exit signs, escape route marking, assembly point signage and safety notices are governed by the applicable fire and safety requirements — determined under NBC 2016 Part 4 and local rules by the fire consultant and the authority having jurisdiction — with fire safety signs addressed in IS 12349 and graphical symbols in ISO 7010. Their position, visibility and illumination are not matters of taste.

Because it needs power for illuminated signs, fixings that suit the wall construction behind them, and coordination with lighting so signs are actually legible. Decided at the end, illuminated signs end up with surface cabling, signs land on glass where nothing can be fixed, and a beautifully specified sign sits in shadow. Ten minutes at design stage avoids all of it.

Adopt a logical, extensible system at the start — usually floor, zone, then sequence — and record it. Numbering invented room by room during a fit-out produces a floor nobody can navigate and a facilities record nobody can use. It also needs to survive future reconfiguration, so leaving gaps in the sequence is sensible.
