The verdict in three sentences
For an engineering and construction firm in Luxembourg, the website serves three audiences first: clients and developers, public buyers and engineering candidates, many of them cross-border commuters. A Luxembourg agency is justified if you want a French, German and English site written and maintained locally, with regular reports from your sites. A remote studio such as Kolonell handles a strong references site very well if you supply photos and technical content and accept a third-party German proofread.
Which criteria matter for an engineering firm?
A structural engineering office, a building services consultancy (HVAC, electrical) or a general contractor does not buy a website for looks alone: it needs readable references, up-to-date prequalification documents and a careers page that attracts people. Here is what each type of provider brings, and what to lock into the contract either way.
| Criterion | Luxembourg agency | Remote studio | Check in the contract |
|---|---|---|---|
| Meetings and site visits | on site, in Kirchberg or Belval | video calls, project manager in your time zone | number of meetings included |
| Languages (FR, DE, EN, Luxembourgish) | often in-house copy in FR and DE | native English or French copy, German by a third party | who writes and who checks each language |
| Site photography and drone | coordinated by the agency | local photographer, third-party cost | usage rights and on-site permissions |
| References and project sheets | often bespoke templates | templates structured by sector | right to remove a sensitive reference |
| Prequalification documents | uploaded by the agency | download area you manage | who updates them and how often |
| Domain, hosting, code | varies by agency | in your name from launch | explicit ownership clause |
| Time to launch | 8 to 16 weeks | 3 to 4 weeks | dated milestones or penalties |
In this market, meetings with technical directors are often held in person. If your partners sign off nothing without a physical meeting, this table leans towards the local agency.

When is the Luxembourg agency the better choice?
It is in specific cases, and it is better to say so.
- Your site must be written natively in German with exact technical vocabulary and updated with every new reference.
- You bid for many public contracts and want a nearby provider to refresh prequalification documents within each tender's deadlines.
- You need integration with internal tools (recruitment software, ERP, intranet) with on-site workshops.
- You want a quarterly photo and video report on your sites, run by the same team.
A remote studio is enough when the site presents references, sectors and services, a careers page and a document area, with content supplied by your teams.
What an engineering firm site must include
- References with large optimised visuals (WebP, AVIF), clients named only with their consent, no invented project values.
- Sector and service pages: structures, building services, envelope, site management, according to what you really do.
- Careers page designed for scarce technical profiles and candidates from France, Belgium and Germany.
- Downloadable tender documents, presented generally, never claiming compliance you cannot prove.
- Health and safety page described soberly, with no statistics or certifications you do not hold.
Frame: the architect and consulting engineer professions fall under the Ordre des Architectes et des Ingénieurs-Conseils (OAI); check with it what you may display. The GDPR applies to your contact and application forms, overseen by the CNPD. Aim for WCAG 2.1 AA; some public buyers ask accessibility questions. This is not legal advice.

Questions to ask both providers
- Who writes the German and who checks it before each release?
- Can I add a reference or a prequalification document myself?
- Are the domain, hosting and code in our name?
- How are received applications stored, and for how long?
- What is the monthly cost after support, and what does it cover?
Mini case study
Illustrative example: Laurent, partner in a building services engineering office at Cloche d'Or, receives a local agency quote of EUR 28,000 excluding VAT for a French, German and English site. He compares it with Kolonell Premium at EUR 8,200, languages set in the quote, plus a German proofread by a freelance proofreader at EUR 1,200 as a third-party cost, so EUR 9,400. The gap is EUR 18,600. Laurent sets aside EUR 4,000 for two site photo reports a year (third-party cost) and hands tender document updates to his assistant, about 2 hours a month.
FAQ
Can a remote studio handle a site in Luxembourgish?
It is possible with Premium at EUR 8,200, the multilingual tier, languages set in the quote, with a freelance translator if needed. Most engineering firms publish in French, German and English, with Luxembourgish as an option.
How long does a site with 25 references take?
Allow 3 to 4 weeks with Kolonell once project sheets and photos are supplied. Local agencies often quote 8 to 16 weeks.
Can I show my clients' logos?
Only with their written consent, especially for public clients. Add a removal clause within 5 working days if a client asks.
Is Growth enough for a 30-person firm?
Growth at EUR 4,500 covers a full references site in one native copywriting language. For three languages and a richer careers page, Premium at EUR 8,200 fits better.
Is maintenance included?
Three months of support are included, then maintenance is on quote. With a local agency, the market assumption is around EUR 150 to 400 per month.
