Garage construction, how much does something like that cost?

Hello, I wanted or would like to know how much a garage construction costs! I would like to add a garage to the right corner of my house, that means I would only need 2 walls + garage door. How much would I have to pay approximately for that, I have acquaintances who would probably brick it as a favor, but what does something like that cost and what kind of roof would I have to put on it??? Thank you very much for your answers, you would really help me a lot with this!

Hello, what do you mean you only need 2 walls, where should the roof rest? You can buy a finished garage and have it installed. It should be in the range of 10,000 euros, of course that depends on the model. But that is only the amount for a single garage, if it should be bigger then it will be more expensive.

Hello, as far as the roof of the garage is concerned, you have to comply with the regulations that exist in every municipality. You need to submit a plan and wait for an approval first. Often garages have flat roofs but that does not look particularly nice.

Hello, most garages have flat roofs but that not only looks stupid, there are also often problems with them becoming leaky over time. A gable roof looks nice when covered with tiles. It should definitely match the style of the house.

Hello,
we received an offer from the construction company for a garage kit. The fixed price is 3500 euros.
(The gate was not electric in this case, of course, it could be added for an extra charge)

However, we are also thinking more about building it ourselves; we have not yet calculated the material costs, but it will certainly be cheaper than having it built.
