Hello, we want to build a house on a site where we previously demolished an old one. This is considered building within an existing property. An architect created a design. Ground floor area: 10 x 14.5 m (33 x 48 feet), with a separate apartment for one person upstairs. A structural engineer was hired to prepare the structural calculations—219 pages in total. The cost just for the structural calculations was €4,285 including VAT. Is this normal?

We also used pile foundations, and the structural engineering documents were included with the building permit application / planning permission. State of Mecklenburg-Vorpommern.

Depending on the house costs and complexity, €3000-8000 is quite normal. Whether it needs to be submitted with the building permit / planning permission application or even reviewed varies by region.

I recently requested several quotes for structural engineering of a single-family house, including reinforcement plans. The prices ranged from 1500€ to 12,000€ (net amounts). I chose the cheapest option because it also had the best references.

1500 euros for structural engineering and reinforcement plans... You can still find many engineers who don't value their own work. What kind of hourly rate is that? 20 euros?

In North Rhine-Westphalia, I did not have to submit the structural calculations with the building permit / planning permission for a new roof.
However, the documents must be submitted to the city before construction begins. § 68 of the NRW Building Regulations explicitly requires three certificates: structural calculations, sound insulation, and thermal insulation. Compliance must also be personally checked and confirmed by the planner.
