Building defects - condominium ownership - is a reduction possible? How much?

Following situation:

* Purchase & construction of a new 4-room ~90 sqm condominium from the developer
* Construction went quite well, communication with the developer also
* For example, the completion was delayed by 8 weeks; he communicated this 6 months in advance and was then also willing without problems to accept a reduction of the purchase price by 2x monthly rent etc.
* All local craftsmen, some of whom I had already hired in my own house
* Developer is a local company, very well known here, engaged in clubs (also personally), has a good reputation, considered a "Mercedes," so somewhat more expensive, which I knew beforehand and am also willing to bear (= pay)

At handover the following defects:

1) some sockets in the hallway and storage room are not on the LS hallway/storage circuit but on the LS living room; I have checked the situation and I am 100% sure this cannot be fixed without major effort. Breaking up the floor / wall to fix it is also out of the question for me. The electrician’s assessment is still pending (he is currently on vacation) but I am sure it cannot be fixed.

2) in the construction description it says "underfloor heating with thermostat in every room" (exact wording I don’t remember). Now we find that the guest WC does not have separate underfloor heating but is connected to the hallway.

Both points are in the handover protocol and the site manager who carried out the handover didn’t make a big fuss. We agreed that I would discuss the further procedure with his boss.

Neither point is really a big problem, but I don’t want to accept everything as it is. Plus, what is stated in the construction description should also be delivered ...

I have no desire to insist on correction of these defects, as both would be major jobs. Plus, the tenant could only move in later or reduce rent, so more stress. I think the developer will see it similarly, as he wants his final payment and then peace.

Can I assume that these two points will result in a reduction of the purchase price?
How high could the reduction for these points be set?

Or is an expert appraisal absolutely necessary? I am not keen on that either, as it means time, effort, money and certainly stress with the developer. So far, the developer has been accommodating. Therefore, I assume he will agree to a reduction.

What do the experts say?

1) Some sockets in the hallway and storage room are not on the circuit breaker for hallway/storage room but on the circuit breaker for the living room; I have checked the situation and I am 100% sure, this cannot be fixed without major effort. Tearing up the floor/wall to fix it is also out of the question for me. The electrician's assessment is still pending (he is currently on holiday) but I am sure this cannot be fixed.

2) The construction description states "underfloor heating with thermostat in every room" (I do not remember the exact wording). Now we find that the guest WC does not have a separate underfloor heating but is instead connected with the hallway.

Regarding 1. Incorrect wiring in the fuse box? Better talk to the electrician first.

Regarding 2. Since when is there a thermostat in the guest WC? I have never seen that in a house either (why should there be?) and therefore do not consider it a defect.

Conclusion from a layperson: Maybe you get a few euros as "depreciation" (because/if there are deviations from the performance description), but I do not see a real depreciation.

In the other forum, you have already received comments that get straight to the point. I wouldn't make a fuss about it either.

Regarding point 2. Since when is there a thermostat in the guest toilet? I have never seen that in a house either (why should there be?) and therefore do not consider it a defect.

In my house. The hallway is often heated for us, the guest toilet is not.

I also have one in the guest bathroom, one in the hallway, and one in the pantry...

One would have been enough!

I don't understand this thread. You build with a "Mercedes". Construction is TOP, communication TOP, Mercedes even pays 2 months of cold rent. And now people are "spinning" conspiracies about how to get 600 €.

Just wait and see what the construction manager says. Maybe it can be managed without problems. You can also tell him you don't want a huge effort but a financial component.

I don't think hiring an expert is appropriate. Or rather, it would be at your expense anyway. The developer is not letting this escalate but is checking.

There are people........
