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!

I marked the area of the garage and terrace.You don’t like my site plan? That’s a pity. Your marking only allows for assumptions. I assume it is a boundary development, which would not be permitted with a roof terrace, as the green area is designated as private green space according to the development plan.

Your outline only allows for assumptions. I assume building on the boundary, which would not be permitted with a rooftop terrace, since the green area is designated as a private green space according to the development plan. Your site plan is our alternative.
On the right side of the house (as seen from the street) I think is the lowest point, so that would be a suitable location for the garage. The entrance would then be on the other side.
Let’s see what ideas the planners come up with. Garages, terraces, and similar structures are allowed to be built up to the property boundary here.

Here is our plan for the positioning of the garage and the house.
Also, here is an excerpt from our development plan. I had understood that terraces and garages do not necessarily have to be located within the building area. However, I am open to being corrected.
If we place the garage in front of the house, we face the problem that it blocks light to the basement. Therefore, we would prefer to position it on the side (see image) and move the main entrance to the other side, so that the terrace and similar areas are located in the southwest.

Here is our planThank you, that is helpful. So the garage should not be built on the property line, and everything is fine. However, the house you have drawn measures only 7.8m by 9m (26 ft by 30 ft), and the garage is only 3m by 4.5m (10 ft by 15 ft).Thirteen schrieb:
I had actually understood that terraces and garages do not have to be within the building envelope.That is correct from a planning permission perspective. It is also correct under building regulations, except if the terrace is on top of the garage. In that case, the required setback distances apply. Under private law, a ground-level terrace must also maintain a minimum distance of 2.5m (8 ft) from the property boundary according to Hessian neighbor law. However, since the neighboring property is a private green space, the neighbor’s consent for this can usually not be refused.You are right. I did not draw the house and the garage in exact detail because we still don’t know the final size of the house.
However, I assume that the garage will no longer fit within the building area. But if I understood you correctly, that is not a problem as long as it is at least 2.5 meters (8 feet) away from the property boundary, right?
