I hope I have provided the most important key points so far to possibly get your assessment. Attached are 3 photos of the upcoming building project. What do you think of the floor plans and the offer?

I appreciate any opinions or assessments.
Best regards

I love the German interpretations of building regulations: single-story 😀

About the floor plan: I'll start from the top. I like it. I could feel comfortable there.
Downstairs, I find the position of the staircase very unfortunate. Anyone going upstairs has to walk through the living area. When the children later run up and down with their friends all the time, mom and dad will never have time or peace for themselves.

Can this be considered a single-story building??? With a clear ceiling height on the upper floor of 2.70 m (8 ft 10 in)???

It's not single-story though 😀

There is the 2/3 living area regulation, which might also depend on the federal state.

Is the plot already owned, or will it be purchased together with the general contractor?

I find the stairway entrance inconvenient. Not necessarily because of considerations regarding children or quiet areas, but for daily use and the longer detour.

The price is 2460€/m² (228 sq ft), which is realistic if it only covers the house.

Well then, gladly: it looks like an office building with the roof of an L-shaped bungalow placed on top.

I actually think the floor plan is good. However, the staircase starting right next to the TV in the cozy corner just doesn’t work; I believe there needs to be a different solution...
