The verdict in three sentences
In Luxembourg, a luxury property developer's website costs EUR 18,000 to 45,000 excl. VAT at a local agency in 2026 and EUR 50,000 to 120,000 at a premium agency with a virtual tour or configurator, a ballpark based on typical local agency quotes. Kolonell's fixed grid is EUR 2,700 (Starter), EUR 4,500 (Growth) and EUR 8,200 (Premium), with a project manager reachable in your time zone, native English or French copywriting, delivery in 3 to 4 weeks (4 to 6 for Premium) and 3 months of support. For a developer, the real spend is elsewhere: properly captioned architectural renderings, up-to-date floor plans and availability, fast enquiry handling and reviewed legal notices.
What a buyer of a prestige development wants to check
The buyer of an apartment in Kirchberg, Belair or Limpertsberg is often an international executive, a cross-border worker settling in or an investor advised by an agency. They reach your site from a listings portal or a broker's recommendation, and they check quickly: who you are, what you have already delivered, where the build stands, what the unit includes. A developer's site must prove solidity before it seduces.
| Page | What it must prove | Trap to avoid |
|---|---|---|
| Completed projects | A real track record of finished developments, with photos of completed buildings | Mixing renderings and completed work |
| Current development | Architecture, location, projected delivery timeline | A date presented as certain |
| Visuals and floor plans | Atmosphere, floor areas, orientation | Renderings without an 'artist's impression, non-contractual' caption |
| Availability | Units available, reserved, sold, kept current | A grid frozen for six months |
| Specification and energy | Materials, fittings, stated energy performance | Vague promises on finishes |
| Team and architects | Who designs, who builds, who answers | An 'about' page without faces |
| Contact and appointments | Fast reply, choice of language, sales suite visit | A form with no acknowledgement |
Off-plan sales are regulated in Luxembourg, and property advertising must be fair to consumers. This is not legal advice: have your lawyer or notary review notices on timelines, guarantees and the non-contractual nature of visuals. Contact forms fall under the GDPR, overseen by the CNPD. Never publish yields, prices per square metre or numbers of units sold unless they are accurate and current.
What Luxembourg providers charge, against the Kolonell grid
| Provider | Build range (2026 ballpark) | Languages usually planned | Typical timeline |
|---|---|---|---|
| Freelancer | EUR 5,000 to 12,000 excl. VAT | Often one, translations extra | 6 to 10 weeks |
| Local agency | EUR 18,000 to 45,000 excl. VAT | French and German, English optional | 10 to 16 weeks |
| Premium property agency | EUR 50,000 to 120,000 excl. VAT | Per quote, with virtual tour | 4 to 8 months |
| Kolonell Starter | EUR 2,700 | Native English or French copywriting | 3 to 4 weeks |
| Kolonell Growth | EUR 4,500 | Native English or French copywriting | 3 to 4 weeks |
| Kolonell Premium | EUR 8,200 | The multilingual tier, languages set in the quote | 4 to 6 weeks |
For a Luxembourg developer, Premium, the multilingual tier, is often the right call: your buyers read French, German or English, sometimes Luxembourgish, and the languages are set in the quote. Starter suits a site dedicated to a single development. Buyer-only areas, integration with a sales CRM, a unit configurator or a 3D tour are on quote. Full details are on the international offer. As a verifiable reference, Kolonell built the website of Orven Properties (orvenproperties.com), a real estate company in Dubai.
Extra costs and a 3-year budget
Whoever you hire, budget for photography and drone video of the site and neighbourhood, a legal review of notices, hosting, then maintenance. Architectural renderings are usually already commissioned for the sales campaign. Assumptions used: photography and video EUR 3,000, legal review EUR 2,000, hosting EUR 600 a year, maintenance EUR 400 a month (EUR 800 for the premium agency), translations for the freelancer EUR 4,500. At Kolonell, maintenance after the 3 included months is on quote: the figure used is only there to compare.
| Option | Year 1 | Year 2 | Year 3 | 3-year total |
|---|---|---|---|---|
| Freelancer (with translations) | EUR 23,900 | EUR 5,400 (market assumption) | EUR 5,400 (market assumption) | EUR 34,700 |
| Local agency | EUR 45,400 | EUR 5,400 (market assumption) | EUR 5,400 (market assumption) | EUR 56,200 |
| Premium property agency | EUR 95,200 | EUR 10,200 (market assumption) | EUR 10,200 (market assumption) | EUR 115,600 |
| Kolonell Starter, one development | EUR 11,900 | EUR 5,400 (market assumption) | EUR 5,400 (market assumption) | EUR 22,700 |
| Kolonell Premium | EUR 17,400 | EUR 5,400 (market assumption) | EUR 5,400 (market assumption) | EUR 28,200 |
In year 1, the Kolonell Premium line reads: 8,200 + 3,000 + 2,000 + 600 + 9 months of maintenance at 400, so 3,600, total EUR 17,400.

When a Luxembourg agency is still the better choice
A local agency keeps the edge if you want weekly meetings at your offices, a German-speaking team on site, direct coordination with your sales agency and sales suite, or a 3D configurator linked to live availability. It also wins for a group launching several developments a year with a brand to build. If what you need is a solid, multilingual developer site live before the sales launch, the budget gap is better spent on video, visuals and legal review.
Questions to ask: who writes in each language, and who reviews it? How is availability kept current? Who owns the domain and the accounts? What response time is planned for incoming enquiries?
Mini case study
Illustrative example: Pétrusse Développement, a fictional developer of a 14-apartment residence in Belair, receives a local agency quote of EUR 38,000 excl. VAT. It chooses Kolonell Premium at EUR 8,200, with French, German and English set in the quote, adds drone video at EUR 3,000 (market assumption) and a legal review at EUR 2,000 (market assumption), so EUR 13,200. Spread over the 14 units, the site costs about EUR 943 per unit, and the EUR 24,800 gap with the local quote stays available for the sales campaign.
FAQ
What does a luxury property developer's website cost in Luxembourg in 2026? Expect EUR 18,000 to 45,000 excl. VAT at a local agency, 2026 ballpark, more with a 3D tour. Kolonell's grid runs from EUR 2,700 to 8,200.
Do we need one site per development? Not necessarily: a brand site with a section per development is often enough. A dedicated Starter site at EUR 2,700 makes sense for a flagship development with its own campaign.
How should architectural renderings be presented? Always captioned 'artist's impression, non-contractual' and kept separate from photos of completed projects. It is a matter of fairness to buyers, and your counsel can specify the expected wording.
How long until the site is live? 3 to 4 weeks for Starter or Growth, 4 to 6 weeks for Premium. Allow 1 to 2 weeks on your side to approve plans, copy and notices.
Which languages should we plan for? In Luxembourg, French, German and English cover most buyers, with Luxembourgish adding a local touch. With Premium, the multilingual tier, the languages are set in the quote.
Let's scope your project. A developer site on multilingual Premium, with floor plans, availability and completed projects, live in 4 to 6 weeks ahead of your sales launch. See the international offer or request a free quote: detailed reply within 48 hours.
