I don't know which carport you calculated, but it doesn't bring that much. I will need the garden house as storage for bicycles, etc. when moving in, and honestly, I wouldn't want to give up the possibility of having a decent garden either. You don't want to trudge through mud for two summers.
I recently read a thread where it was suggested that you can't get a decent carport for less than €17-20k. Therefore, I think it might be worth something if it's foreseeable that the money will run out. ;-)
Regarding the actual topic of interest rates: I wouldn't panic, at least not for the first quarter.
That would be 21 sqm and thus 2,857€/sqm. There must be more to deduct than
7 sqm foundation slab, 3x2xca2.9m facade, 1m more roof, 21 sqm underfloor heating and ceilings.
The cost drivers kitchen, heating, bathrooms remain the same.
Not in Baden-Württemberg in Kfw 40 standard and extra room height. It is also exactly a 1.3 m reduction. That’s just how the calculation came out using the built-up volume method. If it ends up being 50 or 45 thousand euros, I’m happy too. But building more than you need doesn’t make sense either.

Well, that was also a huge one, 6x9 with a storage room across the entire width and from the carpenter including assembly. I am planning a double carport 5x6, which is available from Prikker made of BSH including glued laminated arches and concrete tiles for just under €5000. Of course, you still have the foundations and paving to add, but that's far from that amount. At €20,000, I would never take a carport; you can easily get prefabricated garages for that.
How is it actually, if the value of the house is the same or rather higher, but it was built differently anyway? So 12sqm larger, with a ventilation system and higher-quality heating, but without a prefabricated garage...
