How to achieve Bremer 2/3 solution with high knee wall?

we built with ernst and ernst from Achim, do you already know them?

We actually hadn't considered them yet, but we'll take a look! Thank you very much

I can recommend it 100%, friends of ours also built with them and have been living in the house for 10 years – everything is great!

We also hired an independent building expert who was totally impressed. That reminds me, I still have to write a review :)

Oh yes, and very important, despite Corona and war and so on, we didn’t have a single day of delay. Everything went smoothly.
