Office signage: guiding, identifying, and securing your spaces

Tertiary signage simultaneously addresses three enforceable normative bodies of regulation, which Kytom handles from the audit stage rather than at the end of the project.

The regulatory framework applicable to the workplace requires the marking of emergency exits, the display of fire safety instructions, and a six-monthly periodic inspection of safety lighting. It also conditions the maximum capacity of the floor based on passage units: a single emergency staircase 1.40 to 1.50 m wide allows a maximum of 100 people per floor, a structuring factor for sizing evacuation signage.

Safety pictograms and colours fall under an international normative reference, applied to floors, walls, and door leaves. Visual accessibility requirements apply to character height, contrast, and tactile or braille supports in reception areas.

In practical terms at Kytom, the market treats these three frameworks as separate graphic constraints, managed by the communication studio at the end of the chain. Across 42 projects delivered between 2022 and 2024, this separation generates 60 to 70% of post-delivery reworks. We therefore align enforceable safety, standardised pictograms, and accessibility in a single compliance file from the audit stage, enforceable during safety commission reviews and internal audits.

Typographic sizing conditions the actual legibility of your system, measured from the decision points identified during the audit. Our thresholds combine normative signage references with criteria 10.x of RGAA 4.1, and appear in all Kytom files.

These values are assessed in light of the actual illumination level. A 4.5:1 contrast compliant with RGAA does not deliver on its promises if the brightness of the circulation drops below 200 lux, a threshold below which legibility degrades noticeably in real conditions. Our teams measure illumination before installation, applying the ergonomic principles of indoor workplace lighting, and alert the client in the event of a discrepancy.

When this grid does not apply: on short floors below 400 m² with a single circulation axis and fewer than 3 decision points, standard marking at 50 mm height is sufficient, and the additional cost of a calibrated typographic study (4 to 6 k€) is not worthwhile. Our complete method targets head offices above 800 m² with at least 6 decision points.

The financial reading of a signage project rarely comes down to the initial investment cost. Three lines structure the decision for the finance and asset management departments.

Enforceable compliance and insurance risk. An unfavourable safety commission review following marking that is non-compliant with R4227 may lead to a partial suspension of operations. The cost of an enforceable signage compliance file (3 to 6 k€ included in the package) remains lower than a single day of forced vacancy on a 1,500 m² floor (Paris CBD rent, indicative range 800 to 1,200 EUR/m²/year).

TCO over the lease term. Our supports, guaranteed for 5 to 10 years, significantly reduce the TCO compared to standard solutions renewed every 2 to 3 years, avoiding 2 to 3 renewal cycles over a 9-year lease.

Asset valuation and environmental trajectory. A signage system integrated into the environmental approach (PEFC supports, manufacturing, material traceability) feeds the file and environmental certifications, bearing in mind that BREEAM In-Use certification is valid for 3 years, unlike BREEAM New Construction and Refurbishment, which have no expiry date, or HQE Exploitation, which are recognised levers for asset valuation.

For a tertiary head office of 1,500 to 3,000 m², an integrated signage system generates measurable benefits across four areas: smoother circulation, regulatory compliance (R4227 file, standardised pictograms, RGAA accessibility), visitor reception quality, and TCO control over the lease term thanks to supports guaranteed for 5 to 10 years. On our recent projects, we have recorded no reservations at the safety commission review upon acceptance.

User feedback from our tertiary clients since 2006 highlights four quantifiable benefits, observed across our portfolio of signage projects delivered between 2022 and 2024.

Operational fluidity. Your staff and visitors save circulation time between reception and meeting rooms, a gain measured by before/after timing on several pilot floors.

Enforceable compliance. No reservations at the safety commission review on projects delivered since 2022, with an R4227 file, standardised pictograms, and RGAA provided systematically upon acceptance.

Visitor reception quality. Your hosts and hostesses see their orientation requests drop noticeably, freeing up time for value-added tasks.

Controlled TCO. Significant savings over the term of a 9-year lease thanks to our supports guaranteed for 5 to 10 years, compared to standard solutions renewed every 2 to 3 years.

These four benefits add up and directly feed the ROI observed on head offices above 1,500 m², excluding indirect asset valuation linked to sustainable operation approaches.

1. On-site audit and flow mapping
   Over two weeks, our teams walk through your floor to map visitor and staff flows, measure reading distances at decision points (15 to 40 on a standard floor), and record brightness circulation by circulation. The deliverable: an audit file with a signage plan, an inventory of regulatory gaps regarding fire safety, standardised pictograms, and digital accessibility, and costed recommendations.
2. Graphic design and brand guidelines validation
   Over two weeks, your brand guidelines are translated into a coherent signage system: typography calibrated by distance, RGAA 4.1 contrasts, standardised pictograms, support variations. Validation within 2 to 3 iterations maximum, with decisions presented to your real estate department and your in-house studio if you have one.
3. 1:1 on-site prototyping
   In week 5, we install full-scale mock-ups at critical decision points to test legibility during actual occupancy hours. Your users validate or adjust before production launch, securing the investment and eliminating 90% of post-installation rework requests.
4. Manufacturing in certified workshops
   Over four weeks, our workshop partners produce the supports: aluminium, PMMA, PEFC wood, or acoustic textile, according to your environmental requirements and your obligations to reduce tertiary energy consumption. Material traceability is provided to feed your environmental certification files during the operation phase.
5. Installation in occupied premises and acceptance report
   Over three weeks, our teams install during off-peak hours (evenings, weekends) so as not to disrupt your operations. A detailed acceptance report covers each installed element, accompanied by the enforceable compliance file covering R4227, standardised signage, and RGAA. A hotline 8am-6pm is active for 12 months for any operational questions.
