The different ways an architect is paid in 2025
The price of an architect varies depending on several important factors. You need to understand these different pricing options. Three main formulas exist on the market today.
An architect’s hourly rate: how does it work ?
An architect’s hourly rate is a transparent option. You only pay for the time actually worked. Hourly rates typically range from €80 to €250.
A young architect charges lower fees. Their hourly rate often starts around €80. On the other hand, an established firm easily charges €150 to €250 per hour.
This formula is ideal for small, one-off projects. Consulting appointments often use this billing method. However, the cost can become difficult to predict.
Flat-rate payment : when and why choose this option?
The fixed-price plan offers significant budget certainty. You know the cost of the architectural project from the outset. This method avoids unpleasant financial surprises.
A simple study mission costs between €1,000 and €3,000. This amount includes preliminary analyses and initial sketches. Detailed technical plans also increase this initial budget.
The price of an architectural plan depends on its technical complexity. Execution plans require meticulous and precise work. Their price therefore varies between €1,500 and €5,000 depending on their level of detail.
The percentage on the amount of work: calculation and application
An architect’s average fee is often a percentage. This proportion varies depending on the size of the project. It gradually decreases for larger projects.
The percentage generally ranges from 8% to 12%. This range applies to the cost of the work. However, variations exist depending on your region.
This method remains preferred for complex projects. The construction of an extension frequently uses this formula. It allows the fee to be fairly adjusted to the extent of the work provided.
