Top 8 Architecture web developers in Brussels

In Brussels, a business website typically costs €5,000 – €20,000, while a custom web app runs €20,000 – €120,000. Agency day rates of EUR 80-160/hr are the main driver, followed by integrations and how much custom functionality you need. Tecklogist quotes architecture projects from from €799 at a fixed price.

A business website usually takes 3–6 weeks; a custom web app takes 8–20 weeks. Delays almost always come from late content, unclear scope or third-party integrations, so agree those before work starts.

The usual options are Webflow, WordPress + custom theme, Cargo / Format and Custom static site. The right one depends on how often your team edits content, which systems the site must connect to and your budget, so be wary of any Brussels agency that recommends the same platform for every client.

Ask about large-format project photography that loads fast without sacrificing visual quality, tested on both desktop and mobile; a project-led navigation structure organised by typology or scale, not a single undifferentiated portfolio grid; clear display of professional registration and accreditation relevant to the practice's jurisdiction and project types. Then ask for two or three live architecture websites they built, who will actually work on yours, and what support looks like after launch.

This list is published by Tecklogist, and we rank ourselves first because architecture websites are core work for us: fixed prices, fixed timelines and code you own. The other Brussels agencies are ordered by the architecture evidence in their public profiles, and none of them pay to appear.
