Is Signage a part of the Architecture?
4 August 2026
A well-detailed building can still be undermined by the layer visitors actually read. Five principles for specifying signage on Scottish projects, and what to look for in a signage partner.
Every building has a layer the public reads before it reads the architecture. It sits at eye level, it is usually the last thing specified, and it is often the first thing to date. Signage rarely accounts for more than a fraction of a project’s budget, yet it carries a disproportionate share of the impression a building leaves.
Edinburgh makes this unusually visible. A practice working here might move in a single year from a Georgian terrace in the New Town, to Victorian institutional stone, to a contemporary insertion at Quartermile or on one of the university estates. Each context asks signage to behave differently, and each punishes the same mistake: a scheme designed after the building was finished rather than alongside it.
The symptom is familiar. Three months after handover, a laminated A4 sheet appears taped to a glass door because nobody worked out how visitors would find the accessible entrance. That is not a facilities failure. It is a design gap that was created much earlier, and it is avoidable.
Signage is a material decision before it is a graphic one
Signage is often handed to whoever is producing the brand guidelines, which frames it as a typographic exercise. On a building, the more consequential decisions are physical: what the sign is made from, how its edge is finished, how it meets the wall, and whether it sits proud on a shadow gap or flush in a recess.
Those choices determine whether the sign belongs to the building or merely sits on it. Brushed stainless steel behaves nothing like powder-coated aluminium in raking north light. Solid surface materials hold a crisp routed edge that acrylic will not. Timber ages, which is sometimes the point. Glass demands a rethink of fixings because every one of them is visible from both sides.
Scotland’s climate narrows the field further. Driving rain, freeze-thaw cycling and, on exposed coastal sites around Leith and Granton, salt-laden air will find any specification chosen purely on appearance. Fixing into historic stone raises a second question that is easy to miss until it is too late: how run-off from the sign and its fixings will stain the substrate over a decade, and whether isolating washers or a secondary backing plate should carry the load instead.
Legibility is a design constraint, not a compromise
Accessible signage is still occasionally treated as something that arrives to spoil a clean scheme. In practice the requirements are narrow, well documented, and entirely compatible with good design, provided they are known at the outset rather than retrofitted.
BS 8300-2:2018 remains the working reference for buildings, and the Equality Act 2010 duty to make reasonable adjustments applies across Scotland. The recurring points are visual contrast between text and background (a difference in light reflectance value of roughly 30 points is the usual benchmark), sans-serif typefaces at sensible sizes for the reading distance, non-reflective finishes, and mounting heights that work for a seated wheelchair user as well as a standing adult. Tactile lettering and Braille are expected on room identification in most public and institutional buildings, and audio-assisted signs are increasingly requested on public-sector schemes.
None of this constrains a designer meaningfully. What it does constrain is a scheme designed at Stage 5, when the contrast ratio of an already-approved palette becomes a problem to argue about rather than a parameter to design within.
Wayfinding follows the plan, not the wall
The most common wayfinding fault is not too little signage. It is too much, in the wrong places.
A wayfinding strategy is a reading of the building’s circulation: where a visitor has to make a decision, what they need to know at that exact point, and, critically, what they do not. Signs placed at every junction regardless of hierarchy train people to ignore all of them. Signs that appear only at the decision point, carrying only the information relevant there, get read.
This is a plan-level exercise, which is why it belongs to the architect as much as to the sign manufacturer. It also depends on something outside both their control: the client’s own naming. If the estates team calls a building by one name, the timetable calls it another, and the sign carries a third, no amount of specification quality will rescue it. Agreeing terminology early is unglamorous and saves more confusion than any single design decision.
Design for the building’s second decade
Departments merge. Tenants churn. Wards move. Room numbers get reallocated when a floor is refitted. A signage scheme that cannot absorb any of this will be defaced by the people using it, usually with adhesive labels.
The design response is to decide, deliberately, which information is permanent and which is not. A building name cut from steel can be bonded for good. A departmental listing in a shared entrance should not be. Modular systems with replaceable panels cost slightly more at handover and considerably less across fifteen years. They also preserve the original design intent, which fully bonded graphics rarely survive.
The same logic applies to procurement. Ask whether a matched replacement panel will still be available in year eight, in the same finish, from the same tooling. It is a dull question that determines whether the scheme still looks designed a decade after the photographs were taken.
Consents and coordination happen earlier than expected
Two workstreams routinely surprise project teams.
The first is statutory. External signage may require advertisement consent from the local planning authority under the Town and Country Planning (Control of Advertisements) (Scotland) Regulations, and on a listed building or within a conservation area, listed building consent may be needed for anything affecting character, including fixings into historic fabric. These are not fast processes, and they sit on the critical path more often than the programme assumes.
The second is buildability. Illuminated signage needs a power route agreed with the M&E designer while routes are still movable. Anything heavy needs pattresses or noggins fitted before the wall is boarded and skimmed. Signage that lands on joinery needs its setting-out coordinated with the joinery package, not discovered on site. Every one of these becomes expensive at exactly the moment it is discovered late.
Choosing a signage partner: the questions worth asking
Most signage suppliers can produce a sign. Fewer can hold a design intention across a whole building. A few questions separate them quickly.
Do they engineer, or only fabricate? Ask whether they have developed any of their own sign systems. A manufacturer that has engineered and patented a fixing or modular system has demonstrably solved problems rather than only assembling parts.
Is manufacture in-house? Brokered fabrication introduces a gap between the person who understood the detail and the person cutting the material.
How wide is the material range, genuinely? The test is whether one detail can be carried consistently across steel, timber, solid surface and glass, because most buildings need more than one.
Will they prototype? A physical sample, finish-matched and viewed in the actual light of the actual space, prevents the most expensive category of signage error.
Who owns installation? A single point of responsibility from survey through to the final fixing removes a familiar category of dispute.
When do they want to be involved? The revealing answer is Stage 3 or 4. A supplier who only wants a finalised drawing at Stage 5 is quoting, not collaborating.
For schemes with heritage constraints or a strong design language, specifiers increasingly shortlist manufacturers whose core business is bespoke architectural signage rather than catalogue ranges. These are firms willing to engineer a detail for a specific wall, rather than adapting the wall to suit a standard product.
The layer people actually touch
Signage is the part of a building that visitors read, touch, photograph and remember. It is also the part most likely to be value-engineered on the assumption that it is a commodity.
It is not. It is the final act of the design, and the one most exposed to public judgement. Bringing it into the conversation at Stage 3, as a material, spatial and regulatory question rather than a graphics deliverable at the end, costs nothing and protects everything that came before it.
