ᐅ Retaining a Slope and Backfilling – Additional Costs?

Hello dear forum,

We recently managed to secure a building plot and are now slowly but surely moving into the detailed planning phase.

Our plot has a total slope of 4m (13 feet), with 2m (6.5 feet) within the buildable area. So we almost have the choice: basement or no basement.
If we decide against a basement, higher costs for filling and slope stabilization will arise. The question is: what additional costs should we realistically expect?

We are also currently considering a basement. It doesn't really fit into the budget, but we would consider it if the costs for filling and stabilization are very high. And here again the question: a utility basement with partial heating or a living basement that could possibly be rented out. But that would probably also generate significant additional costs.

Opinions on costs vary here as well. So far, we have been quoted prices ranging from 60,000 to 100,000 euros. What would be realistic?

Our plot is located in a new development area, for which a soil report exists. This report does not indicate any special issues. We will obtain a soil report specific to our plot once we know exactly who we will build with.
Of course, we could also wait until that report is available and then decide, but in fact our choice of builder also depends on the decision about the basement.

I would be happy to receive tips and opinions from you.

Thank you very much!

If I understood you correctly
I’m not sure.
There are three regulations to consider: the zoning plan (planning law), the state building code (building regulations), and the neighbor law (private law). According to the zoning plan, the garage, the terrace, and even the terrace on top of the garage are permitted either directly on the property boundary or at any distance from it.
According to the state building code, the garage is allowed on the boundary or with at least a 1m (3.3 ft) setback under the conditions listed in §6, paragraph 10. However, a roof terrace is not allowed on top of it, because for roof terraces §6, paragraph 8, no. 6 applies:
Terraces that are no more than 1 m (3.3 ft) above ground level or, including their railing, are no more than 2 m (6.6 ft) high.
This condition is not met by the roof terrace, which means that building setback areas apply, requiring a minimum depth of 3m (9.8 ft). I’m leaving out neighbor law here, as in your case it is most likely irrelevant.

Ah, perfect. Thank you very much!

At least now we have a concrete plan and can see what will ultimately come of it.
