Hello everyone!
This is my first post since we started planning to become homeowners.
It’s about the cost estimation—specifically for our earthworks. Here’s what we know about the plot:
- It is 374 sqm (4029 sq ft) in size
- The house has external dimensions of 9.27 m x 11.07 m (30.4 ft x 36.3 ft) and will be built without a basement on a concrete slab
- A garage and a parking space in front of it are planned
- Currently, there is a height difference of 1.30 m (4.3 ft) between the ground level and the underside of the slab, so about 90 cm (35 in) to the bottom edge of the slab
- Our builder will supply 40 cm (16 in) of capillary-breaking material for backfilling (free of charge or included in the house price)
- According to the soil report for the building site (attached, starting on page 33 Baufeld WA 4a*), an average of 40 cm (16 in) of topsoil has to be excavated
- If I understand the above report correctly, no soil replacement is necessary
I wanted to ask for a realistic estimate of the costs involved (excluding utility connections, which I will calculate separately). We are currently estimating around 30,000 euros. Online, I find anywhere between 5,000 and 80,000 euros, which doesn’t really help. The soil conditions are probably not ideal due to the significant amount of fill material.
Looking forward to your advice, and thanks in advance to everyone involved!

Soil investigation was also a significantly underestimated item in my case.
I contacted about ten geologists within a 100km (62 miles) radius. The average net cost quoted was 2000 EUR. In some cases, there was a waiting time of up to 4 months. Our geotechnical survey cost 941.55 euros, in postal code 0457x. We had to pay a bit more because the assessor traveled from further away. However, the survey may have been conducted back in 2020.

However, it might be that the survey was already done in 2020.Well, then you got a good price. Be happy. Postal code here is 676xx. As I said before, this is an average from about 10 quotes, current as of March 2022.
I wouldn’t have expected that even the prices for soil investigations vary so much regionally and/or have increased so significantly. At the end of 2020, we paid a total of 750 EUR for a very experienced geologist … the more “expensive” ones in the area cost between 1000 and 1500 EUR. NRW/Lower Rhine region.
