ᐅ Estimating Shell Construction Costs for an Extension – Who Has Experience?

Hello,
I am planning an extension to our house in about 3 to 5 years.
We have two children, but only one bedroom. When the kids get older, each should have their own room. So, the plan is to build a two-story extension in about 3 to 5 years. This would mean two rooms, one above the other, each with a floor area of approximately 4 x 4.5 meters (13 x 15 feet).
The house is made of brick. I would like to build the extension at the back as a timber frame structure. Is that possible, or could it cause any issues?
Why am I thinking about this so early? Because I am currently paying off my loan, and I’m worried that interest rates will be significantly higher in 5 years. Therefore, I would prefer to save some money now for the extension instead of putting extra payments toward my loan.
My question is: what would such an extension approximately cost?
I am only interested in the following cost items:
- Foundation + concrete slab
- Timber frame + insulation
- Roof
I will do the rest myself or can estimate it on my own.
I really just want a rough cost estimate.
Should I expect around 20,000, or more like 30,000, or rather closer to 40,000 euros?
Maybe someone here has experience with this.
Thanks in advance!
Best regards,
Specki

Yes, I would have done all of that myself.
Since the question was about the roof shape, it’s a simple shed roof.
How does it look in terms of permits? Do I first need a complete drawing and then get it approved?
I basically have almost no documentation for the rest of the house, only a few very old documents, some of which are not entirely accurate.
Is that a problem?
My plan would be like this:
I go to a carpenter and explain what I intend to do and what he should build for me. He creates a drawing, which I take to the authorities for approval. Then the carpenter provides the structural calculations, and I have someone install the foundation slab first. Afterwards, the carpenter completes the shell structure with insulation and roof. The window installer fits the windows and door, and I will take care of the rest myself at a comfortable pace.

No, you’re still quite a bit away from reality.
With the mentioned self-performed work, I would estimate around 55,000-60,000 (currency not specified).
The plans must be submitted by an authorized professional, either an architect or a structural engineer.
Is the whole project even eligible for approval (building permit / planning permission)?
