Is demolition of the existing basement necessary or not?

Submit demolition request, what remains will be marked finished. Consider floor area ratio finished We have left entire rooms and retaining wall standing, as well as walls of the manure pit and basement partially. The latter are filled and not visible

Everything is possible! An architect or structural engineer should check the substance. He will probably hold a carport ;)

So what now? 2000 or 2020?

I am not sure what you mean. Typo?
