The verdict in three sentences
For a property management company in Brussels, a website redesign runs roughly €12,000 to €35,000 with an established agency in 2026, compared with €2,700 (Starter), €4,500 (Growth) or €8,200 (Premium) at Kolonell, with portals and listing feeds on quote. The realistic timeline is 3 to 4 weeks once copy in French, Dutch and English is ready, which is often the real bottleneck. The risks that matter are concrete: broken links to owner and tenant portals, maintenance request forms that collect too much data, and expired listings that vanish without redirects.
Which signals say the site needs a redesign?
In Ixelles, Uccle, Woluwe or the European Quarter, property managers serve three very different audiences: landlords, co-ownerships and tenants, many of them expats working for the institutions. A site built five or six years ago usually shows these symptoms:
- maintenance requests arrive by phone because the online form is hard to find on mobile;
- the Dutch or English version is incomplete, or machine translated;
- document pages (building rules, general meeting minutes, tenant guides) are scattered PDFs with no logic;
- links to owner and tenant portals change every time the management software updates;
- the IPI registration number and legal notices are missing or out of date.
What budget should you plan in Brussels in 2026?
The amounts are a 2026 ballpark, based on typical Brussels agency quotes and public rate pages, with no statistical claim.
| Provider | Site redesign | Three languages | Typical timeline | Watch points |
|---|---|---|---|---|
| Established Brussels agency | €12,000 to €35,000 | Often included, translation sometimes billed separately | 10 to 16 weeks | On-site workshops, maintenance under contract |
| Local studio | €7,000 to €15,000 | Translation extra, €1,500 to €4,000 | 8 to 12 weeks | Limited capacity in busy periods |
| Freelancer | €3,000 to €8,000 | Rarely included | 6 to 10 weeks | Reliance on one person |
| Kolonell Starter | €2,700 | One language | 3 to 4 weeks | Focused site, about 5 pages |
| Kolonell Growth | €4,500 | One language | 3 to 4 weeks | Service, document, blog pages, analytics |
| Kolonell Premium | €8,200 | The multilingual tier, languages set in the quote | 3 to 4 weeks | Advanced animation, deeper SEO |
Every Kolonell package includes a project manager reachable in your time zone, native French or English copywriting and 3 months of support. The detailed scope is on the international offer page.
On quote: connecting or embedding owner and tenant portals, listing feeds to property portals, a login-protected document area, integration with the management software and any custom application. SEO work beyond the migration is also on quote.
How does the redesign run, week by week?
| Week | Work | What the company provides |
|---|---|---|
| Before kickoff | Copy in three languages, list of public documents | Approved translations, registration number |
| Week 1 | URL inventory, 301 map, site structure | CMS, Search Console and DNS access |
| Week 2 | Design and copy integration | Mockup approval within 48 hours |
| Week 3 | Forms, document pages, portal links | Updated link list, inbox for requests |
| Week 4 | QA, compliance review, launch | Legal review of notices, go-ahead |
| After launch | 14 days of redirect and indexing monitoring | Reporting any issue |
Which risks, and what is the fix for each?
| Risk | Symptom after launch | Fix |
|---|---|---|
| Organic traffic loss | Office or neighbourhood pages missing from Google | URL inventory, page-by-page 301 map, 4 weeks of Search Console monitoring |
| Expired listings | Hundreds of 404 errors | Redirect to the matching category or municipality page |
| Portal links | Tenants blocked at login | Link list tested on staging, a named owner |
| Maintenance request form | Excess data (photos of the home, ID documents) | Minimal fields, no ID, set retention period |
| Document migration | Orphan PDFs, outdated versions | Sort into publish, archive, delete |
| Downtime | Lost requests on a rent due date | Mid-month DNS switch, rollback ready |
| Marketing claims | Unverifiable statements | Review of copy and the IPI number before launch |
For tenant data, the GDPR applies, supervised by the Data Protection Authority (APD/GBA): minimise fields, state the purpose, set a retention period. Estate agent or property manager (syndic) titles are shown only if held, with the matching IPI registration. This is not legal advice.
When is a Brussels agency still the better choice?
If your redesign comes with a switch of management software and full synchronisation of properties, owners and tenants, a local agency that knows that tool and can meet on site will often be safer. The same applies if you expect a maintenance contract with same-day intervention. Kolonell fits when the software stays in place and the goal is a clear, trilingual, fixed-price site.

Mini case study
Illustrative example. Sophie runs a fictional property management company, "Gérance de la Cambre", based in Uccle. Her site has 140 URLs, including 70 old listings.
- Quote from a Brussels agency: €24,000, 12 weeks.
- Kolonell Premium: €8,200, French, Dutch and English set in the quote.
- Dutch proofreading by a freelance translator (third-party cost, assumed €1,200).
- Scenario total: €9,400, a difference of €14,600 from the local quote.
- Redirects: 70 pages kept or merged, 70 expired listings redirected to 6 municipality pages.
Portal links stay simple links; an integration would be priced on quote. Illustrative scenario, no result promised.
FAQ
Does a Brussels property manager really need three languages?
French and Dutch serve local clients, English serves expat tenants. At Kolonell that is the Premium tier at €8,200, languages set in the quote.
Are owner and tenant portals included?
Links to your existing portals are built into the site. Any technical connection or integration is on quote, on top of the €2,700 to €8,200 package.
How long does the redesign take?
3 to 4 weeks at Kolonell once copy is ready, compared with 10 to 16 weeks at an established agency. Preparing three languages often takes 2 to 3 weeks beforehand.
What should the maintenance request form ask for?
Property address, nature of the problem, contact details and available time slots. No ID documents; the GDPR requires limiting data to what is strictly necessary.
When should the new site go live?
Mid-month, away from rent due dates and general meetings. Plan 14 days of redirect monitoring after launch.
