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.
