Planned new single-family house - floor plan available

Do we have or is there the exact wording of the development plan?

this is the exact wording:

As roof shapes, gable and half-hipped roofs are permitted for the main roof surfaces - garages and ancillary facilities and green roofs are excluded from this

What I would change: remove the pantry and enlarge the kitchen, enlarge the guest toilet to a real children's bathroom. If the two children's rooms are to be filled with life, they are simply too small!

Pantry... a delicate subject - wife's wish. But I will cautiously try to incorporate the idea... wish me luck.

But: please divide differently! The narrow corridor will never be a dressing room but will always remain a narrow corridor. With this amount of space, there should be a better solution. Do you both need a 12sqm bathroom? Probably not. You can easily take some space from there and add it to the dressing room, but overall please arrange differently...

10sqm bathroom would do for me as well. Personally, I could easily do without a bathtub... but then we are back to the topic of wife and possibly children in the future.

Last but unfortunately not least: the budget will not be enough. At least with this equipment and construction type, I don't see 450k all-in. Do you have a buffer or can you do some work yourself? Then it might (wasn't it Lower Saxony, where it's a bit cheaper in the countryside?!) be doable.

Currently, I save at least 1.3k every month. Buffer is thus steadily increased, even if slightly. With a net income of 3.2 and fixed costs including rent, electricity, insurances, etc. of about 1.1, this is very feasible. And I still treat myself to sugar-free diet soda...
At the moment, we will only do some work ourselves on the flooring and regarding doors (can do). Cost reduction therefore rather limited?!
Edit: Yes, Lower Saxony.

You know: the hyphen (or whatever it’s called) confuses me.
Is there really such a thing in a development plan?
Would you like to post the complete development plan or name the district including the building area?

You know: the separating dash (or whatever it might be called) confuses me.
Does it really exist in a development plan?
Would you like to post the complete development plan or name the district including the construction area?

... the dash really does exist, at least in this development plan.
But it's good that you mentioned it again. I was a bit inattentive myself and definitely should have included the first and third paragraph – or just posted the picture right away.
But see for yourself:

Edit: I apologize for the inattentiveness and for providing incomplete information...

Yes, I read it the same way as you.

I agree with @11ant.

It is correct and important that you point that out; for my statement, I took the passage from the questionnaire as a direct quote and thus as a basis. The excerpt that came last confirms that in my opinion: one almost prefers green roofs, given how often that is specifically emphasized as an exception.

Pantry... delicate topic - wife's wish. I will cautiously let the idea slip in... wish me luck.

We had one planned initially as well. But it didn’t require any luck, just arguments. In rather small kitchens in apartments that certainly makes sense, but if you can plan a kitchen from scratch you (we) actually don’t need it anymore. Our pull-out cabinet is brilliant and exactly designed for the "pantry items," more than enough.

10 sqm bathroom would do for me as well. Personally, I could do very well without a bathtub... but then we’re back to the topic of wife and possibly children in the future.

Then it’s not consistent downstairs as I said. If children, then a bigger bathroom downstairs, the tub can still be upstairs with you, it fits well into 10 sqm.

Currently, I save at least mind. 1.3k every month. Buffer

That’s very good and would already mean approx. a minimum of 15k more by the start of construction, with a rising tendency. It’s essential because:

We will currently only contribute own work for the floor and in terms of doors (can). Cost reduction thus rather manageable?

Yep, more than manageable. Flooring is usually not included in most "turnkey" offers anyway but always own work or commissioned separately. What does the offer say about that again? Same goes for painting work, by the way.
