Single-family house with a ground-level granny flat on a slope

I'll check that. I'll get back to you tomorrow.

With 10% you already have a huge problem in the area of the house connections. Retaining wall 3 m high.

See excerpt from the plan:



I dislike repeating myself, but it doesn't work below 15%.

Can you also please tell me why not, so that I can convince the construction company that it definitely doesn’t work with theirs under <8%. Please be so kind

With 8% you need at least 2 m retaining walls on both the hillside and valley side of the driveway in the area of the house connections. This can work with the stepped house. I am looking forward to the design.

I planned to make the slope steeper at the front and flatter at the back anyway. Am I, with an average of 15% over 55 m, not 1.5 m too high?

I intended to make the slope steeper in the front and flatter towards the rear anyway.

At the outlet, the overhangs are more critical, whereas along the slope curve the wheelbase and ground clearance become more important.
