The verdict in three sentences
In Luxembourg, an engineering and construction firm website built by a local agency costs, as a 2026 order of magnitude, 10 000 to 40 000 EUR, depending on the number of references, languages and integrations (job listings, download area). Kolonell builds the capability pages, project references, careers page and an enquiry form at a fixed price: 2 700, 4 500 or 8 200 EUR, delivered in 3 to 4 weeks for Starter and Growth. For a firm that recruits continuously and bids for public contracts, the real issue is the three-year cost and language management, with German and Luxembourgish supplied by the client or quoted separately.
This version is written for the English-speaking partners and managers of engineering firms based in Luxembourg; the main article is in French.
Luxembourg agency, freelancer or Kolonell: how big are the price gaps?
The ranges below are cautious orders of magnitude, not official rates. They rely on public price lists from agencies in the Grand Duchy and the Greater Region, minimum project sizes on Clutch.co profiles, hourly rates published by Luxembourg digital agencies (often 90 to 150 EUR an hour) and rates visible on Malt and Upwork. Agencies in Metz, Arlon or Trier are often cheaper and deserve the same analysis.
| Criterion | Agency in Luxembourg | Greater Region freelancer | Kolonell |
|---|---|---|---|
| Build, 2026 order of magnitude | 10 000 to 40 000 EUR | 3 000 to 10 000 EUR | 2 700 / 4 500 / 8 200 EUR, fixed price |
| Out-of-scope hours | Often 90 to 150 EUR | Often 55 to 90 EUR | Additions quoted before work starts |
| Usual timeline | 8 to 14 weeks | 5 to 10 weeks | 3 to 4 weeks, Premium usually 4 to 6 |
| Languages | FR, DE, EN often offered | Depends on the profile | Native FR or EN, bilingual FR/EN in Premium; DE and LU supplied or quoted separately |
| Site photos, drone | Sometimes optional | Rarely | No: local photographer booked by the firm |
| Support after launch | Separate contract | Case by case | 3 months, 6 in Premium |
| Ownership | Check the contract | Check the contract | Domain in the firm's name, all access handed over |

What is the three-year cost for an engineering firm?
A firm adds references every year, updates its job listings and sometimes its certifications. We use the same maintenance assumption on both sides, since Kolonell maintenance after the support period is quoted on request.
| Item over 36 months | Luxembourg agency (mid-range) | Kolonell Premium |
|---|---|---|
| Build, FR/EN version | 22 000 EUR | 8 200 EUR, bilingual included |
| German version | 2 500 EUR | Professional translation, assumption 2 000 EUR |
| Maintenance (same assumption) | 160 EUR a month for 30 months, i.e. 4 800 EUR | 4 800 EUR, quoted on request |
| Adding 12 project references | 12 hours at 120 EUR, i.e. 1 440 EUR | Quoted before work, assumption 1 000 EUR |
| Site photos and drone | 2 400 EUR | 2 400 EUR, booked by the firm |
| Indicative total | 33 140 EUR | 18 400 EUR |
These figures structure the comparison. The right reflex is to ask every provider to complete the same table.
What does each package include for an engineering firm?
| Item | Starter 2 700 EUR | Growth 4 500 EUR | Premium 8 200 EUR |
|---|---|---|---|
| Capabilities | One page per main field | Structures, civil engineering, building services, project management | One page per discipline, methods and tools (BIM if real) |
| Project references | Up to 8 | Filters by sector: housing, offices, public, industry | Detailed sheets, firm's role, phase, client with consent |
| Recruitment | Careers page with link | Published jobs and open applications | Jobs by discipline, candidate journey |
| Quality, safety, certifications | Mention | Dedicated page (ISO only if actually held) | Detailed page, downloadable documents |
| Languages | FR or EN | FR or EN | Bilingual FR/EN |
| Support | 3 months | 3 months | 6 months |
A plan-sharing extranet, a subcontractor portal or an intranet is a custom application, quoted on request. Ongoing SEO is also quoted on request.
What a Luxembourg engineering firm needs online
Luxembourg's construction market combines office and housing projects in Kirchberg, Cloche d'Or or Belval, major infrastructure (tram, roads, rail structures) and strong housing demand. Clients are developers, public contracting authorities, general contractors and architects. The site mainly serves three audiences:
- Clients and architects, who check references, capabilities and capacity before consulting the firm.
- Candidates, often cross-border workers from France, Belgium or Germany: the careers page must be clear about roles, location and working languages.
- Public buyers, who review tender applications: the site complements the application file without replacing it.
A few factual rules. Project references should only appear with the client's consent; state the firm's exact role (design, supervision, coordination). In the Grand Duchy, the OAI, the Order of Architects and Consulting Engineers, regulates these professions; check with it how to mention membership and titles. Display only ISO certifications actually held, with their scope. The GDPR applies to forms and applications (CVs are personal data, with a retention period to define), supervised by the CNPD. The European Accessibility Act, applicable since 28 June 2025, mainly targets certain consumer services; a B2B site is not always covered, but WCAG 2.1 AA remains a good reference. This is not legal advice.

Mini case study
Illustrative example. Marc L., managing partner of a 35-person structural and building services firm in Luxembourg, wants a new site before a recruitment campaign. A local agency quotes 24 000 EUR for an FR/EN/DE site in 12 weeks. Kolonell offers bilingual Premium at 8 200 EUR in 5 weeks, and the firm has the German translated for 2 000 EUR.
Build and languages: 24 000 EUR against 10 200 EUR, a gap of 13 800 EUR. With the same maintenance (4 800 EUR) and the same site photos (2 400 EUR), the three-year gap stays at 13 800 EUR. Marc L. chooses Kolonell and asks a German-speaking engineer to proofread the technical pages.
