I think it is especially important to create a thread that possibly shows ways to make progress through diligence and skill without the material requirements increasing every year. I wish the project much success!

Best regards

What’s missing from your list in the first thread is the heat pump and water/sewage. Or do you just not have prices for those yet?

What do you plan to do yourself, and what will you subcontract completely?

Otherwise, good luck with the build

Yes, all of that is included under the building services section.

Wow!
Heat pump + underfloor heating + water pipes + wastewater pipes + shut-off valves, brackets, accessories, etc. for 10,000. That’s going to be tight!

So, now I’ve quickly reviewed it.

I’ll follow this with interest and hope updates will continue.

I don’t see any reason to argue about whether it will work or how much that actually amounts to per square meter.

As we’ve established, the original poster (OP) is building in a very affordable area. Without checking every detail, the shell construction for EUR 73,000 is remarkably cheap.

Everything else in the contracted trades is reasonably priced, though not unrealistically low. The key factor here is the owner’s own work. If the OP can manage this timewise and nothing goes wrong (illness, etc.), it can work out like this.

According to his breakdown, he seems to be a plumber.

If I take the labor costs out of the trades like the OP did and add that in some trades (like plumbing) material savings exceed labor costs, the budget isn’t that far off.

The house seems to be standard in terms of equipment, except maybe for the mechanical ventilation with heat recovery.

For me, very affordable shell construction plus own work in the trades with high labor costs.

I’d be interested in how many working hours @hegi___ calculated.

That would indeed be interesting for “new forum members.”

For 90% of people, the OP’s situation doesn’t apply: neither the available time nor the technical skills, plus most live in more expensive regions.

Heat pump + underfloor heating
With a Geisha unit and doing the work yourself, it becomes really affordable. Around €2,500 for the heat pump, €1,300 for the fresh water station (or less if using only a hot water storage tank), about 2,000€ for 150 sqm (1,615 sq ft) of underfloor heating with the staple-up system. Add some small parts, and the heating system is complete. You just have to do it yourself. There’s even money left for the water supply.
