The verdict in three sentences
For an architecture practice in Amsterdam that enters competitions for public buildings, the website acts as a permanent reference file read by juries and clients. A fast, precise portfolio costs EUR 9,000 to 20,000, with AVIF images, project sheets showing floor area, cost and schedule, and LCP under 2 seconds. A second language, at EUR 3,000 to 6,000, opens German and international markets alongside Dutch and English.
What a jury and a client look at
A client adviser preparing a shortlist spends 3 to 5 minutes on each practice's site. They look for comparable references: a 3,500 m² primary school, a library, a sports hall, with construction cost, scope of services (DNR 2011 phases), completion date and environmental performance (BENG, MPG score, timber construction). A portfolio limited to beautiful images without data forces them to dig through paper files, and the practice loses clarity.
Private clients (developers, housing corporations) look at the same data, plus the ability to hold budget and schedule.
| Site block | Expected content | 2026 budget (EUR) |
|---|---|---|
| Art direction and UX | Editorial grid, typography, 8 to 12 templates | 2,500 to 5,000 |
| Structured project sheets | Program, area, construction cost, scope, completion | 1,500 to 3,500 |
| Portfolio filters | Type, client, status, year | 800 to 1,800 |
| AVIF image pipeline | Conversion, responsive sizes, lazy loading | 900 to 2,000 |
| Practice and team pages | 18 profiles, skills, awards and publications | 800 to 1,700 |
| German version | Architectural translation and DE SEO | 3,000 to 6,000 |
| QA, performance, launch | LCP < 2 s, accessibility, GDPR | 700 to 1,500 |
Performance: heavy images without a slow site
A photographer's architecture shot often weighs 15 to 30 MB. Without processing, a 20-image project page exceeds 100 MB and mobile visitors leave. The image pipeline must convert automatically to AVIF, with WebP fallback, and serve 4 to 6 sizes depending on the screen.
| Indicator | Unoptimized site | Optimized 2026 site |
|---|---|---|
| Hero image weight | 8 to 12 MB as JPEG | 180 to 350 KB as AVIF |
| Project page weight | 60 to 120 MB | 2 to 4 MB |
| Mobile 4G LCP | 5 to 9 seconds | 1.4 to 2 seconds |
| Lighthouse performance score | 30 to 50 | 90 to 98 |
| Monthly image CDN cost | Variable, often uncontrolled | EUR 15 to 40 |
| Time to publish a project | 2 to 3 hours | 30 to 45 minutes |
The CMS must let a team member publish a project in under an hour: drop images, fill fields, approve.
Timeline, languages and upkeep
Allow 8 to 10 weeks: 2 weeks of art direction, 2 weeks of mockups, 3 to 4 weeks of development, 1 to 2 weeks of entering 20 to 40 projects and QA. The extra language runs in parallel if source texts are frozen by week six. Maintenance costs EUR 80 to 180 per month, hosting and CDN included.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Sanne, partner at an 18-person practice in Amsterdam, enters 25 competitions a year and wins 3. She invests EUR 16,000, including EUR 4,500 for German. The structured portfolio cuts reference preparation by 4 hours per competition entry, or 100 hours a year, about EUR 6,500 of time at an EUR 65 hourly cost. If better clarity lifts her shortlist rate from 20 % to 28 %, a single extra competition won on a EUR 4,000,000 construction project represents around EUR 380,000 in fees.
FAQ
Should we publish the construction cost of each project?
Yes for public projects, where the figure is public anyway. For private clients, a range is enough, with their consent.
Why AVIF rather than JPEG?
AVIF cuts image weight by 50 to 70 % at equal visual quality. A project page drops from 60 MB to under 4 MB.
Is a German version worth it in Amsterdam?
For practices targeting North Rhine-Westphalia, Hamburg or Berlin competitions, yes: EUR 3,000 to 6,000 for a market where tenders are published in German.
How many projects should we launch with?
Between 20 and 40 well-documented projects beat 120 empty sheets. Add 1 to 2 projects per quarter afterwards.
Can we show unbuilt projects?
Yes, with a clear status (competition, study, on site, completed). Juries appreciate well-presented lost competitions, which show the design approach.
