If I were the OP, I would refer to the first post. The plans are posted there and with a bit of effort and a calculator, you could have a result relatively quickly, without having to rely on the troubles of a stressed client. But it's just a suggestion
Exactly what I wanted to write just now
Well, in a 1200€/m² thread you can find a hint or two on how to go bankrupt as a BU. Namely by advancing quickly + cheaply, only to have your neck broken afterwards by defect rectification (+Corona). It goes faster than you think.
Of course, I could have taken the next more expensive shell builders, but the 5-10k difference wouldn’t have changed much at 1200€/m² anyway. So far I have paid 61k for the shell. I am cautiously optimistic that we can offset the defects against the remaining payment and that in the end I saved 5k more. What should also be said here is that my focus here, directly after "sufficient" quality, is on the costs. I have never claimed that I am building turnkey here for 1200€/m². Nor have I ever claimed that this project is risk-free and proceeds without partly considerable own contributions.
Thank you very much for your report. I sometimes see myself in the mirror there. Is the flat roof of the garage pitched at 0%?
There is a slight slope.
