Welcome to the forum.
What do you think, is this too big a financial risk for us? Or are the numbers even realistic?
I find the whole thing doable and realistic for now.
The numbers fit. Whether the garage is included and additional construction costs and outdoor facilities, you have to see. Normally, one currently says about €2,500 per sqm living space + additional construction costs + garage + outdoor facilities. 120 sqm with prefabricated garage (small) and additional construction costs as a standard house/equipment should fit.
I can only agree with this. Calculate honestly and then you have to check whether the loan amount fits. €530,000 with €4,500 salary is already a lot. It shouldn’t have to become more.
we are a couple (37 years old)
[..]
We are both employed with about €4,500 net, 1 child planned. We can save about €1,700 monthly.

I come to €2,100 [..] get about €1,200 in parental leave for 1 year.
This will be tricky. Parental leave may last longer than 1 year if you don’t have a daycare spot right away. Is daycare at least free apart from the meal money?
Will you or your partner reduce hours, or do you think you can both work full time? Would that even be realistic?
Because of your age, you can’t reduce the repayment period for long or stretch it out.
