How Much Does an Interior Designer Cost in Belgium?
If you’ve started looking for an interior designer in Belgium, you’ve probably noticed that most studios don’t publish prices at all. We believe you deserve a straight answer before you commit to anything — so here it is.
What drives the price of a design project
Interior design is usually priced per square meter, and the rate is not the same for every project. Three factors move it up or down:
- Project size. Small spaces are the most expensive per square meter — a 15 m² studio still needs a full set of drawings, planning decisions and materials, just like a house. As the area grows, the rate per m² drops.
- Type of visualization. Photorealistic 3D renders take significantly more time than schematic views. They cost more — and for most clients they’re worth it, because you see exactly what you’re approving.
- Material selection. “Actual selection” means real products from real, local suppliers — with exact prices, ready to order. Conditional selection describes the type and character of materials, leaving the sourcing to you.
Typical ranges in Belgium
For a 60–99 m² apartment — the most common project size — a complete design project with photorealistic visualizations and actual material selection typically lands in the €4,000–€7,000 range. A smaller one-room project can start around €1,000–€2,000; large houses of 200+ m² benefit from lower per-m² rates.

What about supervision?
The design project is one thing; making sure contractors actually build it is another. Author’s supervision — site visits, contractor communication and quality control against the documentation — is usually priced from €250 per month, depending on the location of the site and the pace of construction.
In our experience, supervision pays for itself: one prevented mistake on site usually costs more than a year of supervision.
Why cheap design projects get expensive on site
A design project that skips technical documentation looks affordable — until contractors start guessing. Vague drawings mean vague quotes, changes mid-build and disputes about what was “supposed” to be there. A complete documentation set (we work in Revit BIM) lets contractors quote accurately and build exactly what you approved.
