Approximate costs of an "extension"

It’s not that simple. They are supposed to become living spaces, so you have to build them according to the applicable energy standards. That already costs quite a bit. Then you have to connect the heating to the new building -> is the current heating even sufficient for this load? The old building must be extended with doors towards the new building -> check the structural stability of the old building. That quickly adds up to a large sum. The heating alone can cost you 30,000 € if everything has to be done new.

Hello ChriStef,

have you already received any initial cost estimates?
