Hello,
we have a house built on a slope in the family. Currently, there is consideration to construct additional parking spaces / carports (e.g. 2-3 parking spaces + bicycle shed) on the property for personal use and for guests. The planned area for this is to be located directly at the property boundary facing the street, so that cars can drive directly from the street onto the parking spaces / carports. Due to the sloping location, a considerable amount of soil (initial rough estimate approx. 240 m³) would need to be excavated and a retaining wall built to counter the earth pressure. I have roughly sketched the idea of the project in the attached pictures (not to scale). According to the soil report from the original house construction, apart from a thin top layer of topsoil, only claystone layers (decomposed/weathered) and sandstone layers are to be expected there (no rock or similar).

Now we are first looking for an initial rough cost estimate, especially regarding the civil engineering work involved (earthworks + retaining wall construction), i.e., what the construction of parking spaces there alone (without carport) would mean. In this context, I am curious if anyone has already done something similar and could share some initial experience values. Experienced users might also be able to share their gut feeling, because I really cannot estimate any scale from-to. Many thanks in advance for any assessment!
