ᐅ Structural Shell Contractor / Structural Shell Cost Estimation – How Do They Calculate?

I also find the design quite inconsistent.
The focus seems to be on parking spaces for vehicles, and from there it just gets stranger.
What is the purpose of the furnished apartment? Who is supposed to sleep in the storage room, and why are there two beds in the bedroom?
The hallway in the main apartment is almost as large as the too-small bedroom, while Junior has plenty of space.
The study is too small, making it uncomfortable.
Why is there a workstation in the living room, and why is the guest toilet so large that it takes away the space needed for the kitchen?

I have two firm turnkey offers, excluding landscaping. One for 800,000 and another for 850,000. Both from reputable local companies. Apart from the recessed attic floor (a requirement from the municipality), the house is relatively simple.

Yes, and with encouragement plus additional construction costs, you're easily looking at 1 to 1.5 million.

The furnishing is really awful, but that can still be changed. The house style is like liverwurst on bread—just a matter of taste with this bunker style.

- Ground floor: plenty of space; hobby area for motorcycle/car
- Small room as a nursery for toddlers or as a dressing room
- Hallway in the main apartment should not be too large. Behind it, a utility room (please look carefully)
- Study should not be large
- WC in the attic floor slightly bigger to store cleaning supplies. No storage room available there

So if I apply the current index for Baden-Württemberg alone, I get 624,000 (1300 * 480).

There must already be a specification of services, or how else were the offers put together?

Yes, there was a detailed folder with many specifics. However, the exact breakdown of the shell construction costs was not clear from it... that’s why I’m asking where I can get a typical shell construction bill of quantities. I would adapt it for my case and use it to obtain initial quotes to get a sense of the price...
