The verdict in three sentences
For a 12-person architecture studio in Amsterdam, an agency rebuild costs 9,000 to 20,000 EUR excluding VAT in 2026, versus 3,500 to 8,000 EUR with a freelancer and about 25 EUR per month for a Squarespace template. The gap is justified by a structured project portfolio (one page per project, filters by programme, client and floor area) that competition juries and public buyers check before shortlisting. Plan 8 to 10 weeks, half of which goes into sorting photos, writing project pages, optimising images and meeting European Accessibility Act (EAA) expectations that apply since June 2025.
Agency, freelancer or template: what you are really buying
An architecture studio website is first of all a reference library. In a design tender, the submission often points to the website: a jury that opens a slow page with three blurry photos and no project data moves on to the next file. The choice of provider depends on how deep you want the portfolio to be.
| Option (2026 order of magnitude, Netherlands) | Initial budget | Annual cost | Project portfolio | Lead time |
|---|---|---|---|---|
| Squarespace or Wix template | 0 to 600 EUR | 300 EUR (25 EUR/month) | Simple gallery, no filters | 1 to 3 weeks |
| Freelance WordPress | 3,500 to 8,000 EUR | 500 to 1,000 EUR | Basic project pages | 4 to 6 weeks |
| Local agency, custom build | 9,000 to 20,000 EUR | 1,500 to 3,000 EUR | Structured pages, filters, map | 8 to 10 weeks |
| Agency specialised in architecture | 20,000 to 35,000 EUR | 2,500 to 5,000 EUR | Project stories, video, 3D | 10 to 14 weeks |
| Partial rebuild (portfolio only) | 4,000 to 7,000 EUR | unchanged | New project module | 4 to 5 weeks |
A template remains sensible for a two-partner practice working mostly for private clients. Beyond 10 people, and once public commissions exceed 30 % of revenue, the structured project page becomes a sales tool in its own right. Accessibility matters too: the EAA mainly targets consumer services, but Dutch public buyers increasingly ask for WCAG 2.1 AA compliance from their suppliers, and an accessible site is easier to defend in a tender.
The portfolio that wins public competitions
An effective project page answers a public buyer's questions in under 30 seconds: which programme, what floor area, what construction budget, what delivery date, what environmental performance. Storing this data in fields (not free text) lets visitors filter « schools » or « social housing » in one click.
| Project page element | Role for a jury | Production effort |
|---|---|---|
| Programme, gross floor area, budget | Check the scale of references | 15 min per project |
| Client and delivery year | Prove recent public commissions | 5 min per project |
| Labels (BENG, BREEAM, bio-based) | Meet environmental criteria | 10 min per project |
| 8 to 15 AVIF photos | Show build quality | 1 to 2 h of sorting and export |
| Simplified plans and sections | Read the design concept | 30 min per project |
| 200 to 350 word text | Explain concept and constraints | 1 h per project |
| Team and role (lead, partner) | Clarify responsibilities | 5 min per project |
The most underestimated item is imagery. A JPEG photo shoot often weighs 2 to 4 MB per image. Exported in AVIF, these images are usually divided by 4 with no visible loss, bringing a 30 MB page down to 7 or 8 MB and making the site usable on a phone in a jury room. Lazy loading, responsive sizes and alt text (also an accessibility requirement) complete the setup.
Typical 8 to 10 week schedule
- Weeks 1 and 2: scoping, sitemap, selection of the 20 to 30 projects to feature (a 12-person studio often has over 80 in its archive).
- Weeks 3 and 4: designs for the home page, project list and project template.
- Weeks 5 to 8: build, project entry, AVIF export, technical SEO (tags, structured data, sitemap), Dutch and English versions.
- Weeks 9 and 10: mobile testing, accessibility audit, team training on adding projects.
The real bottleneck is internal: partners signing off texts. Block two half-days during scoping.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Thomas, managing partner of a 12-person architecture studio in Amsterdam (illustrative example), answers about 15 competitions and tenders a year. He picks a 14,000 EUR rebuild with 25 project pages. Cautious assumption: a clearer portfolio lifts his shortlisting rate from 20 % to 27 %, roughly one extra shortlist per year. If an average design commission brings 75,000 EUR in fees and he wins one in three shortlists, the expected gain is about 25,000 EUR a year. In this scenario the rebuild pays for itself in under 7 months, not counting inbound private enquiries.
FAQ
How much does an architecture studio website redesign cost in Amsterdam in 2026?
With an agency, expect 9,000 to 20,000 EUR excluding VAT for a custom site with a structured portfolio. A freelancer costs 3,500 to 8,000 EUR, and a specialised architecture agency can exceed 30,000 EUR.
How many projects should the portfolio show?
Twenty to thirty complete pages beat 80 galleries without data. Keep projects from the last 5 to 8 years and references that match the markets you target.
Does the European Accessibility Act apply to my studio site?
The EAA mainly covers consumer-facing services, so a B2B studio site is rarely directly in scope. Still, aiming for WCAG 2.1 AA adds about 5 to 10 % to the budget and helps in public tenders.
Is AVIF supported by all browsers?
Yes, all recent browsers read it in 2026, and a WebP or JPEG fallback can be served automatically. The average gain is a factor of 4 on photo weight.
What lead time should I plan before a competition deadline?
Allow 8 to 10 weeks for a full rebuild. If a competition comes earlier, a two-step launch (portfolio first) is possible in 4 to 5 weeks.
