I think this is all way too vague.
Ultimately, it can only be judged whether you can manage €1,800 with your possibilities/income etc.
Yes, you can.
Currently, nothing else can really be assessed. For that, you need to have many more conversations with the architect and need reasonable offers.
A lot of things for us only dissolved into thin air when we found out what various things cost... Your girlfriend will also quickly say goodbye to some things once you’re deeper into the matter, believe me.
And really only take the advice of your parents that is worthwhile. 60% is no longer relevant these days. Parents still claim to know all about the circumstances, which is usually not the case. If then the daughter, your girlfriend in this case, lets herself be talked into too much, it leads to totally wrong expectations. To me, it reads as if that’s going in this direction... Do your thing and if possible, mostly leave your parents out of it.
Here, I have to agree with some people in the thread. Then usually things come like:
- You need a party basement, we had that too!
- Electric shutters, no one needs those, we don’t have them either!
- Ventilation system -- What’s that? You don’t need it!
- Garage – ABSOLUTELY necessary! How can you not build a garage?
- Basement – Basically NO option to do without one.
As you can see... things just change way too much in this area.
--> Also the topic of free planning and a lot of DIY work. Think about that really carefully!! Just because in the past the percentage of craftsmen and own work was much higher and that used to simply be “standard,” doesn’t mean that it still makes sense in your case today. Ultimately, you are building the house, not your parents! The craft has also continuously evolved. No idea if all the retirees can still manage it like that today.
