Built-up letters – front-lit
The light shines forward through the face: the letter itself lights up. The most eye-catching version, visible from a distance. The choice along a busy road or between competing façades.
Built-up letters are individual three-dimensional letters fixed separately to your façade. They give depth and a high-end impression that a flat panel never achieves. The question is not whether you light them, but how: front-lit, halo-lit, or not at all. That choice decides how your façade looks after dark — whether you stand out or stay understated.


The light shines forward through the face: the letter itself lights up. The most eye-catching version, visible from a distance. The choice along a busy road or between competing façades.

The light is thrown backwards onto the façade. The letter stays dark and stands out against a halo. Subtler and more refined — the choice for offices, hotels and brands that would rather not shout.

Three-dimensional, with a cast shadow in daylight, but invisible after dark. The choice when a permit rules out illumination, or when your premises are only visited during the day.
From first sketch to maintenance — one partner who handles everything in-house.
You call one number. We measure, design, produce, install and maintain. No fragmented responsibility, no waiting on subcontractors pointing at each other.
A 3D visualisation of your own façade or space, by day and by night. We only start producing once that image is right. No surprises afterwards.
Custom work from our own workshops, without intermediaries. That means a shorter lead time, a sharper price, and changes that are genuinely still possible.
ISO 9001 and ISO 14001. Colourfast, weather-resistant materials and energy-efficient LED lighting. With long-term service and maintenance.
Built-up letters are individual three-dimensional letters, each fixed separately to the façade. Because the façade stays visible between the letters, the result looks more refined than a flat panel — with depth and cast shadow that a sign board never achieves.
The three versions differ not in material but in the direction of the light, and that changes everything about the effect. The question is not whether you light them, but how.
The light passes through the face of the letter: the letter itself lights up. This is the most striking version, visible from a distance. The logical choice along a busy road or on a business park where you have to stand out among other façades.
Also called backlit letters. The light is thrown backwards onto the façade: the letter stays dark and stands out against a halo of light. More subtle, and generally perceived as more upmarket. The choice for offices, hotels and brands that prefer not to shout.
No lighting. Still three-dimensional, with cast shadow in daylight, but invisible after dark. The choice when a permit does not allow illumination, or when your premises are visited only during the day anyway.
We produce in plastic, aluminium or a combination of both, in any RAL or PMS colour. Aluminium is the choice for large letter heights and for façades near the coast or along a busy road; plastic is lighter and more economical for smaller heights.
You receive a 3D visualisation of your own façade beforehand, by day and by night, so you can compare the three versions side by side before anything is produced. That is the moment to have second thoughts — not once the letters are up.
There is no square-metre price for built-up letters, and that is not an evasive answer. The price is set by letter height, the number of characters, the complexity of the typeface, the material and the method of illumination. A short name in a sans-serif typeface thirty centimetres high is something entirely different from a handwritten logo a metre and a half high with halo lighting.
On top of that comes installation, which depends on the façade: working height, substrate, and whether a lift or scaffolding is required. For illuminated versions the power supply counts too — the distance to a connection point determines how much work goes into the façade itself.
That is why we quote per project and not per letter.
Prices are available in the Herva-Doublet Platform.
Illuminated signage requires an environmental permit in virtually every Belgian municipality. Unlit letters are usually simpler, but local rules on dimensions and positioning apply there too.
We know how the process normally runs and supply the drawings and material specifications that go with such an application. Do start in good time: the processing period is usually longer than production.
Send us a photo of the façade and your logo, and we will draw the three versions on your own building and place them side by side. You will see at once which effect suits your business.
What you see here is a selection. Our range is considerably wider — in sizes, materials and finishes that we cannot all show online. Tell us what you need it for and where it has to go, and we will work out what fits.
