The verdict in three sentences
For a luxury real estate agency in Brussels, the website has to win over two audiences: sellers in Uccle, Ixelles or Woluwe deciding who will market their townhouse, and international buyers, often connected to the EU institutions, who discover properties from abroad. A Brussels web agency remains the best fit if you want a partner who coordinates photography, drone footage and virtual tours of listings, for 8 000 to 35 000 EUR. If your visuals come from your usual photographers and the goal is an elegant, fast showcase that carries the IPI and EPB disclosures, a fixed-price remote studio (2 700 to 8 200 EUR at Kolonell) delivers in 3 to 4 weeks.
Which criteria separate a Brussels agency from a remote studio?
In prime real estate, each signed mandate is worth several times the price of the site. The decisive criterion is therefore the site's ability to generate valuation requests from sellers and to present properties with the expected discretion (off-market listings on request, hidden addresses).
| Criterion | Brussels web agency | Freelancer (Malt, local) | Kolonell (remote studio) |
|---|---|---|---|
| Time-zone overlap | Full (Central European Time) | Variable | Good: team based in Dakar (GMT), 1 hour apart in winter, 2 hours in summer |
| Meetings at your office | Yes | Sometimes | No, video calls only |
| Photos, drone, virtual tours | Often coordinated | Rarely | Not offered |
| Copywriting languages | French, Dutch, English depending on agency | Depends on profile | Native French or English; Dutch quoted on request |
| Price of a full site | 8 000 to 35 000 EUR | 2 500 to 9 000 EUR | 2 700, 4 500 or 8 200 EUR |
| Typical timeline | 8 to 14 weeks | 4 to 10 weeks | 3 to 4 weeks |
| Domain and code ownership | Check the contract | Often unclear | In the real estate agency's name |
These ranges are a 2026 ballpark, drawn from public price pages of Belgian web agencies, minimum project sizes on Clutch.co profiles and hourly rates posted by freelancers on Malt (often 50 to 90 EUR per hour in Brussels).
What does each option cost over three years?
Assumption: a Premium-sized bilingual FR/EN site, with neighbourhood pages, listing pages, a qualified valuation form and a section for international buyers.
| Item | Brussels web agency (mid-range) | Kolonell Premium |
|---|---|---|
| Bilingual site build | 22 000 EUR | 8 200 EUR |
| Dutch version | Often included or 3 000 EUR | Quoted on request (hypothesis: 3 000 EUR on both sides) |
| Support included after launch | Depends on contract | 3 months included |
| Maintenance years 1 to 3 (same hypothesis) | 3 x 1 800 EUR | 3 x 1 800 EUR |
| Hosting and domain (same hypothesis) | 3 x 500 EUR | 3 x 500 EUR |
| 3-year total | 31 900 EUR | 18 100 EUR |
Maintenance after the 3 months of support is quoted on request at Kolonell: the 1 800 EUR per year line is a hypothesis applied to both columns. Automatic syncing of listings from your property software (Whise, SweepBright or another) is an integration quoted on request. Everything is detailed on the international website offer.
Which disclosures and rules apply to your site in Belgium?
- Professional disclosures: an estate agent licensed by the IPI (Professional Institute of Real Estate Agents) shows their title, IPI number and company number (BCE/KBO), in line with the information duties of the Code of Economic Law. The IPI code of ethics governs advertising: no misleading information about a property or about services.
- EPB: in the Brussels-Capital Region, every sale or rental advert must state the energy class and the indicators from the EPB certificate. Each listing page must therefore include these fields.
- GDPR, enforced by the Data Protection Authority: privacy notice, prior consent for non-essential cookies, retention period for valuation requests.
- Accessibility: aim for WCAG 2.1 AA as the practical target.
This is not legal advice.
When is the Brussels agency the better choice?
- You want one provider for the site and the visual production of listings: photos, drone, 3D tours. Kolonell does no photo or video shoots.
- Your clientele is mostly Dutch-speaking or Flemish and the site must be trilingual FR/NL/EN from day one, with an agency writing all three languages natively.
- You value meetings at your office on Avenue Louise or in the Sablon.
- You want an owner portal or a buyer area with documents: that is an application, quoted on request at Kolonell, and a local agency can provide on-site follow-up.
Which questions should you ask both providers?
- Will the domain and code be in our agency's name from day one?
- Do listing pages include the EPB fields required in Brussels?
- How does the valuation form qualify sellers (municipality, property type, sale timeline)?
- Can we publish an off-market property visible only after registration?
- Who writes the English copy for international buyers, and is it native?

Mini case study
Illustrative example. Laurence D. runs a five-person prestige agency in Uccle, specialising in properties from 1 to 3 million EUR. A web agency quotes her 24 000 EUR and 12 weeks; Kolonell Premium costs 8 200 EUR for a bilingual FR/EN site delivered in 4 weeks. Gap: 15 800 EUR.
A sale at 1 800 000 EUR with a 3 % fee brings the agency 54 000 EUR. A single extra mandate won through the valuation form pays for the site more than six times over. Laurence keeps her usual photographer, paid per listing as before. Kolonell has built the trilingual FR/EN/AR site of Orven Properties, an off-plan real estate advisory in Dubai for international investors, with project pages and investor guides.
FAQ
Can the site be in French, Dutch and English?
The Premium tier at 8 200 EUR covers a full bilingual FR/EN site. Dutch is not included and is quoted on request.
Can you import our listings automatically?
Syncing with your property software is a custom integration, quoted on request. Without it, listings are published manually in the content manager, in a few minutes per property.
What is the time difference with the team?
The team is based in Dakar (GMT): 1 hour apart in winter, 2 hours in summer. A project manager stays reachable in your time zone during the 3 to 4 weeks of the project.
How does payment work?
By bank transfer, 50 % at kickoff and 50 % at delivery, with 3 months of support included.
Do we need to meet?
No, everything happens over video calls. If in-person meetings are essential for you, a Brussels agency will be a better fit.
