The verdict in three sentences
For an architecture firm portfolio in Amsterdam, a freelancer at about 6,000 EUR works if the site stays stable and you accept availability risk. An agency at about 15,000 EUR is justified when the 40-project portfolio must evolve every quarter, load fast despite heavy images and help win competitions. Over 3 years, if you publish a dozen projects a year, the gap reverses once maintenance, additions and contingencies are counted (in Bordeaux, the same comparison is 3,500 versus 9,000 EUR).
Day rates and scope: what you are really buying
The upfront price gap mostly reflects the number of days and the profiles involved. A freelancer combines design, development and build. An agency splits work between an art director, a developer and a project manager.
| Criterion (2026 estimate) | Freelancer Amsterdam | Agency Amsterdam | Bordeaux reference |
|---|---|---|---|
| Day rate | 550 to 750 EUR | 950 to 1,200 EUR | 350 to 500 / 600 to 800 EUR |
| Days billed | 9 to 11 | 13 to 16 | 8 to 10 / 12 to 15 |
| Price of 40-project portfolio | 6,000 EUR | 15,000 EUR | 3,500 / 9,000 EUR |
| Dedicated art direction | Rarely | Yes | Same |
| Delivery time | 4 to 8 weeks (calendar-dependent) | 5 to 7 weeks | Same |
| Availability risk | High (holidays, illness, other clients) | Low (backup team) | Same |
| Code and account ownership | To negotiate | Usually contractual | Same |
Image weight, the architects' technical trap
An architecture portfolio typically shows 8 to 15 visuals per project, or 400 to 600 images. Unprocessed, each photo weighs 2 to 6 MB and a project page exceeds 30 MB. Google penalises slow pages, and clients often browse on mobile.
| Format and processing | Average weight per image | Project page (12 images) | 4G load time |
|---|---|---|---|
| Raw camera JPEG | 4 MB | 48 MB | 20 s or more |
| Hand-compressed JPEG | 600 KB | 7.2 MB | 4 to 6 s |
| Resized WebP | 250 KB | 3 MB | 2 to 3 s |
| AVIF with responsive sizes | 150 KB | 1.8 MB | 1 to 2 s |
| AVIF + lazy loading | 150 KB (3 visible at first) | 450 KB initial | under 1 s |
Ask explicitly in the quote for automatic WebP and AVIF generation, responsive sizes and lazy loading. A freelancer can deliver this, but it is often the first line cut to hold a low price.
Total cost over 3 years (Amsterdam)
| 3-year item | Freelancer | Agency |
|---|---|---|
| Build | 6,000 EUR | 15,000 EUR |
| Maintenance and updates | 2,880 EUR (80 EUR per month) | 5,400 EUR (150 EUR per month) |
| Adding 36 projects (12 per year) | 12,150 EUR | 675 EUR (self-service CMS, support) |
| Hosting | 720 EUR | 900 EUR |
| Takeover by another vendor (30% probability) | 1,500 EUR weighted | 0 EUR |
| Estimated total | 23,250 EUR | 21,975 EUR |
The 9,000 EUR upfront gap reverses: the agency ends up about 1,300 EUR cheaper over 3 years once the firm publishes 12 projects a year. If you publish only 2 or 3 projects a year, the freelancer keeps an advantage of about 7,800 EUR.
Mini case study
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Julien, partner at a 9-person architecture firm, publishes 12 new projects a year. With the Bordeaux freelancer, each addition costs 225 EUR (half a day at 450 EUR), 2,700 EUR a year. With the agency, the CMS lets him enter a project in 40 minutes, keeping 150 EUR a year of support. Over 3 years, the savings on additions reach 7,650 EUR versus the freelancer, so the 5,500 EUR upfront premium is recovered in about 26 months. In Amsterdam, with higher rates, the payback is similar at around 28 months. One competition won with a stronger portfolio, worth 40,000 EUR in fees, makes the question secondary.
FAQ
What does an architecture portfolio website cost in Amsterdam?
About 5,000 to 8,000 EUR with a freelancer and 12,000 to 18,000 EUR with an agency for 40 projects. Maintenance adds 80 to 200 EUR per month.
How do we limit freelancer availability risk?
Require the code in a repository in your name, hosting access and documentation. A takeover then costs 1,500 to 3,000 EUR instead of a rebuild.
WebP or AVIF for architecture photos?
AVIF cuts weight by 30 to 50% versus WebP at equal quality. Serve AVIF with an automatic WebP fallback.
Can we update projects ourselves?
Yes with a well-configured CMS: a 12-image project goes live in 30 to 45 minutes. Make sure it is in the quote.
What timeline should we expect?
Allow 5 to 7 weeks with an agency, and 4 to 8 weeks with a freelancer depending on their calendar.
