Floor plan of the existing house was not executed correctly. What now?

Constant dripping wears away the stone and with our approach we are making progress.

Now we had the floor plans created by having someone come on site to take measurements, calculate the living space, and then send us floor plans and sections. The whole thing cost us about €1500. So far so good. However, in the floor plans, the were simply placed arbitrarily and only remotely match reality.

I remember. For this property, truthful plans would be desirable, especially since there are already some that no longer correspond to the actual condition. The price sounds like the usual offers from freshly graduated architects not yet registered in the chamber, while the execution sounds like most overpriced rip-off. That you could really get for one and a half grand.

An online company commissioned, which advertises the execution of this service according to the living space ordinance or DIN277. I don’t think I’m allowed to mention the name, right?

Correct, for potentially contentious "accusations" against dodgers there is a moderated special section here.

The measurements also do not match those from the survey we have separately.

For the purpose of use in bank documents, this could therefore be seen as a forgery. Did the rascal sign his "calculation" based on the wrong data?

I would reject the invoice and try to reclaim any payment already made in this regard. The drawing itself, even printed out, remains childish scribbles and as such just a rip-off, selling it at a carnival price. But the calculation of an area certificate according to DIN is a qualified service which, in my opinion, was clearly not performed flawlessly here.

I would reject the invoice and try to retract any transfer that may have already been made in this regard. The drawing itself remains, even when plotted, child’s scribbles and as such just a rip-off to hawk it at carnival prices. But the calculation of an area verification according to DIN is a qualified service, which in my opinion was clearly not impeccably provided here.

How do you want to retract a transfer? You can try to demand it back!

Serve the notice of defects in writing and demand improvement within the deadline.

How do you want to recall a transfer?

I have not had to use this option yet, only in case of unauthorized direct debit.

Does not work with a bank transfer either. Only with direct debits.
