Prefabricated house / Shell house

closed shell construction 130sqm with window and front door 100,000,- feasible

sanitary heating with gas condensing boiler without any frills 13,000,- feasible

electrical installation 7,000,- feasible

interior plaster 8,000,- such plastering crews really exist

screed 4,000,-

tiler bathroom WC and the rest 11,000,- feasible

interior doors 3,000,- feasible

makes 146,000,-

+ ancillary construction costs

The budget was rather 150k including incidental construction costs. And where is the intended basement etc? Where are floor coverings etc, the essentials for outside? It was said that maybe it could be done with a reduced scope. Don’t troll along. From on the go

From mechatronics technician to mechatronics technician, find another forum. 95% here don’t take a step outside without experts, assessors, energy consultants, lawyers, and other clairvoyants.

Your approach is ambitious yet feasible

Greetings from Singapore

and so easily offended

they have no idea how a craftsman is networked

at least 10 electricians and heating engineers in the circle of acquaintances

3-5 tilers
2-3 plastering crews or screed

in the village three guys who can handle an excavator like the devil

but I don’t know any lawyer

What could be problematic if someone inquires about [Schwarzarbeit]...

Did you actually read the original post from the OP?

Budget 250,000€ TOTAL. The land is about 90,000€, so the house can cost 150,000€. We have received many offers from Allkauf Haus or Ling4you or Massa Haus. But there are so many that you lose track.

I can do a lot myself. Electrical, plumbing, and underfloor heating will be done, also the basement will be partially cellar. The offer from Allkauf Haus for 157,000€ is currently our number 1

Plumbing heating with gas condensing boiler without any frills 13,000,- doable

No gas condensing boiler, because he wants/gets a KfW55 house:

At that price everything is included. As described above, the basement and the stairs of course KfW 55.

And the 150,000 were all-in. With you, the additional construction costs are on top.

And he also has a partial basement included.

No, no
