The verdict in three sentences
In Brussels, a website for an architecture firm built by a local agency usually costs between 6 000 and 35 000+ EUR (2026 ballpark, depending on scope), and a freelancer typically quotes 2 500 to 9 000 EUR. Kolonell builds the site at a fixed price of 2 700, 4 500 or 8 200 EUR, with a project manager reachable on Brussels time, native English and French copywriting and delivery in 3 to 4 weeks. For an architecture firm, the real gap lies in three items that quotes rarely spell out: project photography and image rights, the Dutch version and support after launch.
What does an architecture firm website cost in Brussels in 2026?
The ranges below are deliberately wide 2026 ballparks. They draw on sources you can check: public rate cards of Brussels agencies, Clutch.co profiles that list minimum project sizes and freelance platform rates (Malt, Upwork). They are not official figures; they vary with the number of projects shown, the languages and the level of visual finish.
| Option | 2026 ballpark | Typical timeline | Usually included | Support after launch |
|---|---|---|---|---|
| Full service Brussels agency | 12 000 to 35 000+ EUR | often 8 to 16 weeks | art direction, custom design, sometimes photography and three languages | monthly retainer, quoted |
| Graphic design studio | 6 000 to 15 000 EUR | often 6 to 12 weeks | refined design, copy often supplied by the firm | hourly |
| Freelancer | 2 500 to 9 000 EUR | 4 to 10 weeks | adapted theme, copy and images supplied by you | ad hoc, hourly |
| Kolonell Starter | 2 700 EUR | 3 to 4 weeks | project manager, native copywriting, domain in your name | 3 months |
| Kolonell Growth | 4 500 EUR | 3 to 4 weeks | same commitments, wider scope fixed in the quote | 3 months |
| Kolonell Premium | 8 200 EUR | written schedule, usually 4 to 6 weeks | bilingual FR/EN site available | 6 months |
Hourly rates commonly published by Belgian web agencies often sit between 80 and 150 EUR: that is the price of every change outside the scope. The page count and exact features of each Kolonell tier are fixed in writing in the quote; current details are on our international website offer.
What a Brussels architecture firm website must show
- Project pages: each project with the brief, the floor area if the client agrees, the year, the team and partners (engineers, landscape architect), plus a carefully laid out gallery. This is the core of the site and the reason a client contacts you.
- Sorting by type: multi-unit housing, renovation of Brussels townhouses, public buildings, offices, interiors. A developer and a private client do not look for the same thing.
- Image rights: architectural photographers usually grant specific usage rights; check that they cover the web. For a private home, get the owners' written agreement, and never publish an address or an identifiable interior without consent. Competition renderings sometimes belong to several parties.
- Competitions, awards and publications: a factual page, no superlatives, with verifiable references.
- Team and method: partners, architects, skills (energy performance, heritage, public tenders), the stages of a commission.
- Qualified contact: a short form (project type, location, timing, indicative budget) to sort enquiries.
- Languages: in Brussels, clients are French speaking, Dutch speaking and international. Kolonell writes natively in English and French; a bilingual FR/EN site is available from Premium. The Dutch version is supplied by the firm or quoted separately.
- Compliance: GDPR applies to forms and analytics, supervised in Belgium by the Data Protection Authority. The Order of Architects sets professional conduct rules that the firm must check for its communication. This is not legal advice.
An honest point: Kolonell does not include on-site photo shoots. If your projects have never been photographed by a professional, the photography budget outweighs the website itself, and a Brussels agency working with an architectural photographer may then be the right choice.
How do you compare quotes and read the 3-year cost?
Two quotes at 5 000 and 20 000 EUR rarely describe the same site. Put each proposal in the same grid.
| Question to ask | Why it matters | Kolonell answer |
|---|---|---|
| How many projects are laid out? | Galleries are most of the work | number fixed in writing in the quote |
| Who writes the project texts? | Often excluded from low quotes | native English or French copywriting included |
| Is the Dutch version included? | Can add 15 to 30 % to an agency budget | supplied by the firm or quoted separately |
| In whose name is the domain? | You must keep it if you change provider | in your name, all access handed over |
| What does support cover? | Retainers often start the next day | 3 months, 6 on Premium, then quoted |
| How is payment split? | A large deposit shifts the risk to you | 50 % to start, 50 % at delivery, bank transfer or Wise |
Red flags: a domain in the agency's name, a mandatory 24 month maintenance contract, a design presented without a mock-up of the project pages, photo rights never mentioned, and a promise of first page on Google. A serious quote states the number of projects, the languages and who supplies the images.
Mini case study
Illustrative example, not a real client. Sophie runs a 6-person architecture firm in Ixelles focused on renovation and multi-unit housing, with English-speaking partners and many international clients. She wants to present 15 projects in English and French. Quote A, Brussels agency: 18 000 EUR, three languages included, plus 250 EUR per month of maintenance. Quote B, Kolonell Premium: 8 200 EUR in EN/FR, plus a Dutch translation she hands to a translator for 1 500 EUR (assumption).

| Line over 3 years | Brussels agency | Kolonell Premium |
|---|---|---|
| Build | 18 000 EUR | 8 200 EUR |
| Dutch | included | 1 500 EUR (assumption) |
| Support | 250 EUR x 36 months = 9 000 EUR | 6 months included, then 30 months x 180 EUR = 5 400 EUR (Sophie's assumption, to be quoted) |
| Total | 27 000 EUR | 15 100 EUR |
The photos already exist, taken by the firm's usual photographer, with web rights confirmed. The 11 900 EUR gap pays for two new project shoots. Her maintenance figure is only an assumption: at Kolonell, maintenance after the included period is quoted.
