Interior signage includes all signage used within a building to support navigation, identification, safety and brand communication. This can range from wayfinding and directory systems through to feature branding, wall graphics and decorative lighting elements.

The most effective interior signage is planned holistically. Rather than treating each sign as a standalone item, layouts, materials and finishes are aligned so the environment feels intentional and easy to understand.

Interior environments typically use a combination of the following approaches, selected based on visibility requirements, aesthetics and practical constraints.

Brand & feature signage
Often used in reception areas, focal walls and key spaces to reinforce brand identity. This can include Built-Up Letters and Laser Cut Acrylic Signs, with illuminated options such as LEDentity used where stronger presence or visibility is needed.

Decorative and statement lighting
Used to add character and atmosphere while still communicating brand or messaging. Formats such as LED neon-style signage are often specified here, including systems like LumiNeon or SustaiNEON where energy efficiency or visual softness is important.

Wayfinding and information signage
Practical signage that helps people move confidently through a building, commonly delivered through Wayfinding Signage, Directional Signs and Directory Signs, supported by safety and compliance signage where required.

Interior signage focuses on usability and experience within a building, while exterior signage is primarily about visibility and attraction from outside. The two are most effective when designed together so messaging and visual language remain consistent.

Some interior projects require illuminated signage for impact or visibility, while others rely on non-illuminated solutions for a more discreet aesthetic. Both approaches can coexist within the same environment when applied thoughtfully.

Interior signage improves how a building functions day to day. Clear navigation reduces confusion, brand features reinforce identity, and well- placed information helps people feel comfortable in unfamiliar environments.

It also plays a key role in how a space is perceived. Offices, venues, healthcare and education environments all benefit from signage that feels aligned with the architecture and interior design rather than added as an afterthought.

JD3 begins by understanding how people move through and use the space—arrival points, destinations, pause areas and decision points. From this, we define the right mix of signage types rather than defaulting to a single solution.

Materials, finishes and fixing methods are then specified to suit lighting conditions, surface types and durability requirements. Signage is manufactured and installed with precision so it integrates cleanly into the interior rather than competing with it.
