Complete interior finishing including filling, sanding, painting, doors, floors properly done alongside work in 3 months as a non-craftsman?

I would have the tiles in the bathroom and probably also in the utility room done by someone else. This is only to be directly assigned by the general contractor or the company itself, since the equipment is supposed to be different. I would have to think about that again.

Filling, sanding, wallpapering, floors, and doors. Yes, it will be challenging and a lot of work.

If it takes 6 months, then it takes 6. We don’t immediately need one or two rooms, so the bedroom and living room/kitchen and hallway would have priority. I don’t come from a wealthy family with an inheritance to throw money away. The 15k I might save with this may not be much in relation to the total sum, but I still think it’s a lot of money that I can use elsewhere. In the end, I hopefully also learn many skills that can be useful for later maintenance.

If it takes 6 months, then so be it 6.

But it will then also take 6 months longer, during which you a) service the financing and b) simultaneously pay your rent if you do not want to move into a half-finished house. In the end, the savings may be very small, whereas the stress and physical effort are very high.

However, I would rather take a moment to reflect seriously on whether the offered equipment is sufficient for me and then possibly find out what that costs based on samples.

A fitting statement, because that is often where the wheat is separated from the chaff. The equipment is certainly simple but can still be nice, so I would take a close look beforehand or have it clearly explained to me what the extra cost is for swapping, for example, the bathtub model XY from manufacturer Z, shower fittings, and much more. Because only then do you have YOUR house and can see the actual price.

It might also be worth considering whether you lay a floor in some rooms that you can actually do relatively easily yourself and still make it look nice, such as the utility room, guest bathroom, or similar; sometimes I at least find there are too many tiles. Nowadays there are really stylish options that are not worse than tiles.

Plastering really has to be done expertly; for us it was the specialist or even several, and yet it is not "perfect."

I believe that through intensive and clever planning, an absolutely honest approach to the equipment (what do I really want/need) you can save the most money.

Hectic or prematurely finalized planning can be sanded off later, not with four tennis arms. Seemingly insignificant, unnecessarily planned details can cost or save so much money.

What kind of professional background do you actually have? Have you ever done or even learned any kind of manual work?

It is important to set realistic goals and not plan 70 hours of personal work per week for 6 weeks of annual vacation. That simply won't work.

Look deep into my avatar's eyes, then it’s quite easy.

If it takes 6 months, then so be it. We don’t need one or two rooms immediately, so the bedroom and living room/kitchen and hallway would have priority. I’m not coming from a rich family with an inheritance to throw money away. The 15k that I might save with this may not be much compared to the total amount, but in my opinion still a lot of money that I can use elsewhere.

You have to finance the entire construction with construction money, meaning the house “move-in ready.” Financing the delta between a shell house and a turnkey house outside of the construction financing with a consumer loan is practically unmanageable.

However, I would rather take a good look at myself and seriously reflect on whether the offered equipment is sufficient for me, and then possibly find out what that costs on samples.

An apt statement, because this is often where the wheat is separated from the chaff. The equipment is certainly simple but can still be nice, so I would look at it closely beforehand or have it clearly explained what the extra cost is for changing from, for example, bathtub model XY from manufacturer Z, shower fittings, and much more. Because only then do you have YOUR house and can see the real price.

Every re-sampling costs more as well as upgrading and even downgrading samples. That’s exactly the trick with the shell house: that there are then no construction service description positions to change. And this principle also applies to the remaining basic or step package positions just like with turnkey houses. So “technically finished” without changing stairs / heating / bathtub / tiles and the like!
