Exemption application help help

Good evening,
We want to build a semi-detached house with a garage!
The architect & surveyor have submitted the building applications, but unfortunately it will not be approved like this!
Our garage is too high!

Now my question is:

Who has to pay for the change now?
Because more earth has to be excavated now etc.

Now my question is: Who has to pay for the change now? Because now more earth has to be excavated et

That depends on what is stated in your contracts with the architect and surveyor. Rhineland greetings

Oh god, what kind of contracts? I only have a construction contract, but there is nothing in it that makes me any wiser! Normally, we don't have to pay this, do we?!

I cannot answer that - without knowledge of your contract for work and services. What do you think the architect and surveyor did wrong; both?

Rhenish greetings

Who has to pay for the change now?
Because now more soil has to be excavated et

If they had applied correctly from the start, this soil would have had to be excavated as well, right?
Do I understand it correctly that the garage is now being lowered? Only the application was wrong?

What was calculated in advance and what do you have to pay now? The difference?

The garage now has to be lowered, so more soil must be excavated and a retaining wall constructed!

I don't know exactly how much more it will cost! We only found out today that it has to be built this way!

I simply think that the surveyor & architect did not measure and calculate properly!
