The verdict in three sentences
A portfolio website for an architecture practice in Amsterdam costs EUR 12,000 to 30,000 excluding VAT in 2026, delivered in 6 to 10 weeks, with maintenance around EUR 120 per month. The budget depends on three things: image processing quality (AVIF under 200 KB), the structure of project pages and the pages that reassure public clients. A EUR 300 per year Squarespace template works for a solo architect, not for a practice that enters competitions.
Three project levels and what they include
Public clients (municipalities, housing corporations, provinces) check your website before or during tender evaluation. They look for comparable references, floor areas, construction budgets and team composition. Typical Amsterdam and Randstad ranges in 2026 (estimates).
| Level | Scope | Projects online | Budget excl. VAT | Timeline |
|---|---|---|---|---|
| Customised template | Premium theme, gallery, contact | 10 to 20 | EUR 5,000 to 9,000 | 3 weeks |
| Custom portfolio | Dedicated design, project pages, typology filters | 40 | EUR 12,000 to 19,000 | 6 weeks |
| Advanced portfolio | + competition pages, team, publications, NL/EN | 40 plus | EUR 20,000 to 30,000 | 10 weeks |
| Option | Embedded 3D tour or drone video | Per project | EUR 400 to 1,000 | : |
| Option | Copywriting for 40 project pages | 40 pages | EUR 3,500 to 6,000 | +2 weeks |
| Recurring | Maintenance, hosting, backups | : | EUR 120/month | : |
The custom level is the sweet spot for a mid-sized practice: a design that reflects your architectural language, and a CMS where the team adds a project in 20 minutes. In Amsterdam, a bilingual Dutch and English site is the norm rather than an option.
Images: the technical item that decides everything
An architecture portfolio holds 400 to 800 high-resolution photos. Poorly processed, they produce 15 MB pages that take 8 seconds to render on mobile, and Google penalises that. The image pipeline must be automatic: you upload an 8 MB JPEG, the site generates the right versions.
| Format or setting | Average photo weight | Load time on 4G | Recommended use |
|---|---|---|---|
| Raw camera JPEG | 6 to 10 MB | 4 to 7 s | Never online |
| Compressed JPEG 2400 px | 600 to 900 KB | 0.8 to 1.2 s | Press downloads |
| WebP 1920 px | 250 to 400 KB | 0.4 to 0.6 s | Fallback for old browsers |
| AVIF 1920 px | 120 to 200 KB | 0.2 to 0.3 s | Main display |
| AVIF 800 px (thumbnail) | 30 to 60 KB | Under 0.1 s | Grids and filters |
| Lazy loading | 0 KB before scroll | : | All galleries |
With this pipeline, a 15-photo project page weighs under 3 MB and scores above 90 on Lighthouse. High-resolution files stay available in a press area for architecture magazines.
Structuring project pages for public clients

Each project page must answer a jury's questions: brief, client, gross floor area, construction budget, completion year, scope of services, sustainability labels (BENG, BREEAM, circular building). Filters should sort by typology (housing, schools, offices, transformation), by status (completed, on site, competition) and by public or private client.
Competition entries deserve their own treatment, with the ranking achieved and the boards. A team page listing skills (BIM, sustainability, heritage) also helps with tender applications.
Mini case study
Daan, partner at a 12-person Amsterdam practice, enters 25 public tenders a year with a 12% shortlist rate, about 3 projects. He invests EUR 22,000 in an advanced portfolio, plus EUR 1,440 of annual maintenance. If the site lifts the selection rate to 16%, the practice wins 1 extra project a year. With average fees of EUR 70,000 per commission, the gain is close to 3 times the total investment of EUR 23,440 in the first year. The team also saves about 2 hours per tender by reusing project data from the site: 50 hours a year.
FAQ
How much does an architecture firm website cost in Amsterdam? Between EUR 12,000 and 30,000 excluding VAT for a custom portfolio in 2026. A customised template starts around EUR 5,000 but limits the number of projects and filter quality.
What timeline should we plan? 6 to 10 weeks for a custom site, provided photos and project data are ready. Copywriting for 40 project pages adds about 2 weeks if we handle it.
Why AVIF rather than JPEG? An AVIF photo weighs 3 to 5 times less than a JPEG of equivalent quality, 120 to 200 KB instead of 600 KB. Pages render in under 2 seconds and SEO benefits.
Can we manage projects ourselves? Yes, the CMS lets you add a project in 15 to 20 minutes with typology, area and budget fields. Maintenance at EUR 120 per month covers updates, backups and security.
Do we need Dutch and English? In Amsterdam, yes for most practices: public clients expect Dutch, international competitions expect English. Bilingual setup adds roughly 15% to the build budget.
