Boundary construction on a non-rectangular plot (NRW)

On the other hand. Does this garage, shrunk by a few centimeters, really hurt? Sure, the risk that someone will notice is low. But why take a risk for so little added value? You can hardly use the space on the slanted wall properly anyway.

What is the risk? If approved, he is allowed to build like that; if not, they usually get notified beforehand (so before the official rejection) and then the plan is simply corrected and the change submitted afterward. Or do you want to build with [freisteller]?

I see it the same way as . Whether someone notices it or not, I would just let it come to that.

There could be up to 50 cm of space. Since the garage wall would only need to be rotated slightly, space losses would only be expected in the front area of the house or garage. In this respect, I see it the same way, that it is still possible to weigh the options here.

There's nothing to weigh up. If you build like that, it violates guidelines. Just because the overwhelmed building inspector stamps it doesn't make it legal and also means no legal claim for you if push comes to shove. Especially since you're not unaware, otherwise your architect would have told you. It's quite possible she lets herself sign that she has pointed it out to you ;) Neighbors can change, you can get into disputes, etc. It’s not worth it to me. But go ahead.

Thank you for the assessment! Then I better not inquire at the building authority to avoid waking sleeping dogs

Mind you, provided the architect did not give the hint based on local knowledge concerning the nitpickers at the building authority.

If approved, he may build like that; if not, they usually give notice beforehand (i.e., before an official rejection), and then the plan is corrected and the change submitted afterwards. Or do you want to build by exemption?

That is an important hint: building by exemption would be risky, however in my opinion not so much:

If you build like that, it violates guidelines. The fact that the overwhelmed building inspector stamps it does not make it legal and also does not give you a legal claim if push comes to shove.

With exemption, the risk exists that the then not formally given "approval" may be lost if the fact comes to light. With approval, this indeed also has a protective and, if necessary, practically healing effect. A demolition order would be disproportionate here, and a violation, which the judge himself realizes only on the seventh glance, usually does not lead to an exorbitant penalty. The architect of course would not be allowed to withhold testimony about having given the hint while under oath. At most ninety daily rates to the nitpicker widows’ support fund or social service ;-)
