Building maintenance land in Hochwald/Hunsrück - Current development costs?

Development costs or connection costs?
The former, which you are asking about, are all the costs to make land habitable. Including roads, parking areas, street lighting, and yes, also the connections. For us, that was €40/sqm. However, 70 other owners are also involved. Earthworks for roads, etc., depend on the geotechnical report. So if you have poor soil conditions or expensive paving is used, many parking spaces as well as green areas and trees, then it becomes more expensive. It also depends on the tender how expensive the company is.
Later, the connection costs to the utility providers follow, which each builder must apply for independently for their property. These costs can be found on the utility providers' pages of the district or can be inquired by phone.

So on the internet (general research) the development costs are about 12-15k euros,

Hello, no, not yet, but the municipality has already allocated 55k euros for the development of the building area for 2022/23. So something is already underway
