What does your architect say about all this? He will not only look at the house alone but also keep an eye on the [site].

No, I actually haven’t, but that’s exactly why I’m bringing in a professional company and actually expect them to know what they’re doing... But since I don’t have that feeling, I opened this thread as a precaution and you guys agree with my feeling...

Unfortunately, yes, our architect completely failed and is a real PeXXer... I don’t want to go into it in detail because it would just bring the anger back up. We are done with him as well, final invoice is paid and that’s it... His contribution to our house can clearly be limited to "draftsman," everything else came from the house provider. And he had no answer to any of our questions about the house, always had to ask the house provider. When it came to the garden, his answer was, that will come later, it’s too early for that. Which was his standard answer to everything. So unfortunately, no thought was put into this here and we are now looking for others who can help us.

I have now created a few pictures, 1-4 show our idea (all pictures with houses that look like blocks ;)). 5-7 show the current site, difficult to capture in one picture, 3D is much better to illustrate it...

Actually, I made that for you to show you where the lowest point is. We would have placed the cistern here and a channel should somehow be possible there. Even if it doesn’t always look like it in the pictures, all the L-blocks I placed are the same height. The wall behind us is also made of 2m L-blocks even though I drew it as a continuous wall.

Yes, it definitely has to be done by a specialist company. But it is much more than a small boundary fence; it is effectively its own structure. Which is surely supposed to stand for several decades. Certainly longer than the company building it will exist. Maybe I am seeing it too complicated, and insurance companies handle it quite easily... but at least I would – just like with building a house – try to secure as much as possible in terms of planning (i.e., structural analysis, soil survey of the hillside area, if necessary qualification of the executing company).

Since I am also dealing with this topic, I found the following searches quite insightful:


    [*
      OLG Dresden – Case No.: 14 U 381/13 – Judgment of 24.06.2014 (Liability for material defects – missing residential building stability due to collapse-prone retaining wall) ... especially chapter:
      [LIST]
      [*]4.1.2. Deviation from own planning/structural analysis
      [*]4.1.3. Omitted soil investigations
      [*]4.1.4. Infiltration




    [*]"Natural stone for dry walls for slope support, hillside and dam stabilization," originally intended for public road construction, but contains many basics for the general topic.

You apparently have the monetary problem. I would keep the terrain slightly lower than the wall. Along the wall, a Bircorinne. Drain everything into the cistern. Cistern, for example, by Graf. They come elongated, flat, etc. Dimension it properly large right away. This way you have enough water for the garden even in dry times. Also sufficient capacity for heavy rain. Direct everything possible into the cistern. Connect the overflow to the sewer. That was permitted for us. We have a 76,000 liter cistern. A fence belongs on the wall. I fear you were poorly advised and no one told you what the earthworks and garden construction will cost... We have even higher walls. This allows proper terracing. But that must be approved and also costs money. L-stones are certainly the cheapest solution. But you have to adhere to the manufacturer's specifications. Are you planning with a basement? Why not dig out more and also have daylight in the lower ground floor? That way you wouldn't have such a steep slope.

Is there anywhere an original site to be seen?

Alternatively to the overflow, one could also use the cistern pump to pump the water into a higher-level channel from a certain fill level. Wilo has suitable pumps, controls, etc. but please do not ask about the prices.
