DGIR Conseil is an engineering firm specialised in flat-roof waterproofing, building renovation and maintenance, working on both public and private contracts.

Their know-how is solid: more than 37 years of field experience, but no proof of that track record online. No website, no online presence to rely on. For a prospect looking for a serious engineering firm, that absence can do real harm: their credibility can't be checked anywhere.

The stake for DGIR Conseil? Laying the first stone of their digital credibility and turning a simple visitor into a concrete inspection request.

The challenge lay in the format: saying everything clearly, on a one-page site.

We had to translate decades of field know-how into one clear, convincing page: expertise, services, past projects, maintenance, without overwhelming the visitor or diluting the message. Each section had to find its place and steer the visitor towards one single goal: the inspection request. All with a site that is fast, secure and GDPR-compliant from day one, on a controlled budget and timeline.

1.Desktop and mobile design
We designed a bespoke interface, built first for readability and trust, and adapted cleanly from desktop to mobile.
2.A one-page journey, built for conversion
We structured the whole site into sections that tell the story of the trade and lead to getting in touch: hero, expertise, inspection, services, before/after projects, maintenance, about, legal notice. The before/after projects do most of the convincing.
3.Built end to end, without a CMS
Rather than a heavy CMS that the project didn't need, we built the site from scratch, with all the content centralised in one place. A tool that is easy to update for non-technical people, not an overbuilt machine.

To build a quality showcase website, everything comes down to the details and the choices visitors never see. Here's what we did for DGIR Conseil:

100% static (Astro 5), no server runtime
An ultra-fast site, cheap to host, with an almost non-existent attack surface.
Self-hosted fonts instead of the Google Fonts CDN
No IP address sent outside the EU, for full GDPR compliance from the start.
Images optimised from the outset (responsive WebP)
Sharp, lightweight visuals, sized exactly to never slow the page down.
A single JavaScript interaction (zoom on past projects)
Only what's needed, nothing superfluous, for speed and reliability.
Basic SEO and JSON-LD structured data (LocalBusiness, SIREN, VAT)
The site is understood by search engines as soon as it goes live.

To deliver a premium, fast and compliant website, we selected several technologies:

A first online presence in just 10 working days

Until now invisible online, DGIR Conseil now has a clear, credible showcase, worthy of its 37 years of experience. Enough to turn a simple visitor into a prospect!
