Is the cost of a shell house realistic?

Hello everyone,

we are currently planning a bungalow on a basement.

Bungalow 147sqm, roofing offset shed roof, trapezoidal sheet metal, 10 degree roof pitch.
Walls solid made of lightweight concrete.
Many glass surfaces
Plastered.
Architect, structural engineer, etc. are included,....
The offer for the foundation slab will be about 1200 euros/sqm.
Is that realistic?
Region: close to the Rhine-Main metropolitan area
I am guessing 800-1000 euros/sqm that I will still put into the interior finishing.
What do you think?

Sorry, but I absolutely cannot imagine that price-wise.

Okay why? What would be more realistic price-wise?

Who does the interior work? You with an after-work crew? Then it might work. Or paid craftsmen? Then 1200 again. Why? The interior work is partly very labor-intensive. Also, some materials, tiles, interior doors, floor coverings, wallpapers, paints, heaters are not cheap.

Hi, I have some trades within the family. But not the first ones. Therefore, we want a shell house. Is the price for the shell house realistic?

I don't know that. Didn't you get an offer?
