Do I understand correctly: you initially thought that a general contractor (GC) building your house could also quickly lay the blockwork for the double garage while excavating the pantry, and now you’re surprised that they won’t do it for a symbolic fee; so now you are open to other GCs to see if they offer a more attractive bundled deal?
There is no garage that comes “included” with a new house like rubber mats come with a new car. Get used to the idea that garage construction is not “customer service” but a business with profit expectations. And take the logical step to tender the two work packages separately.
I took your message

We have decided on the Röben Aarhus light gray clinker brick for our new build. Now we need to choose the window colors.

to mean that your building project https://www.hausbau-forum.de/threads/grundriss-einfamilienhaus-ca-180-qm.44935/ is already quite advanced (?)

Which construction company exactly is that in Bad Wünneberg Leiberg?
I’ve found several there:
1. Rust...
2. Unserh...
3. Schmi...
4. Dons...

Do their names have inappropriate endings that you don’t want to say them in the presence of ladies?
I am sure you will get the help you need. You know that I do this professionally (and I’m not the only one). The contact methods are known ;-)

I understand that a double garage isn’t going to be free.

I just hope for a price that is fair for both sides.

The €13,000 just for the foundation slab doesn’t currently give me the feeling that we are being treated fairly.

We have stayed with our general contractor and are currently in the implementation phase.

I am now looking for a construction company that would like to work with us to build our double garage at a fair price 🙂

Finding a company that offers these services seems to be really difficult at the moment.

[...] Finding a company that offers this work seems really difficult right now.

I already said that the 13k was a cutthroat price for more or less just a concrete slab. But a "fair for both sides" price does not exist for a double garage: either the necessary profit margin is no worse than if the workers were assigned to building living spaces, or the client finds the price for a small industrial hall overpriced. The principle is almost identical to a non-usable basement without added value. On the other hand, a garage is best suited for self-build – if you are willing to make small compromises (such as single garage doors instead of one wide double door).

So what exactly is being built now? Have you managed to get a decent floor plan?

It is the company UnserHaus from Leiberg. However, I doubt that they would provide you with a separate quote for a brick garage. Their main business is building single-family houses.

Exactly – it makes more sense the other way around: by simultaneously purchasing a house, you qualify for the construction of a small hall that is generally less appealing to residential builders.

Yes, unfortunately the company has canceled.

We have now contacted two local, smaller construction firms.

The first provider estimates the construction costs at around €10,000 (about $11,000) 🤨

The second provider estimates the construction costs at around €20,000 (about $22,000) 🙄

Both were briefed on the scope of work to be carried out.

However, we will first have the detailed construction drawings and structural calculations done, and then request a formal and specific quote.
