what could be the cause if there is condensation on the outside of the vapor barrier? that is, not against the insulation but towards the room. it can be noted that I have no heating on and it's around 0 degrees outside. it does get warm from lamps etc.
I am really worried about moisture, have been throughout the entire construction and maybe I am overreacting about small things, but it feels better to ask than to wonder.

Not an expert on moisture. But probably your wall (the plastic) is cold, and when you turn on your lights and the air inside warms up somewhat, the moisture in the air condenses on the still cold plastic.
It should be similar to the condensation that forms on the bathroom window when you've showered.

So it's a new build?
Then moisture is normal, it's called construction moisture, and that it condenses against the outer wall, which is the coldest surface, I see as completely normal.
All wood needs to dry out, even the concrete slab (if you have such).
I would definitely have installed a construction fan to raise the indoor temperature to at least +10°C and arranged some kind of ventilation.

Jo is a new build, the condensation is now towards the inside of the house. I was planning to start the underfloor heating and run a dehumidifier as soon as I finish the last insulation in the ridge before I seal the plastic. Yes, I have a concrete slab. Just for fun, I checked the frame timber with a moisture meter this week, and it showed 12% almost everywhere.
Perhaps the concrete slab is responsible for most of the moisture then.
How old is the slab?

I cast the slab almost exactly 2 years ago.
Wow, that's planning for the long termBobbarebygg said:
But perhaps it hasn't been covered, exposed to the weather?
Then it probably won't dry out very well.
Well then I'm doing everything myself and in addition a full-time job that I actually don't have time for
I've only had it covered with a tarp, started building the house now this summer

isolde: Have installed 50mm west coast board and 145mm insulation then plastic
It is enough to heat the space and ventilate it, and the moisture will disappear.
Similar problems can occur in unheated buildings during winter, such as summer cottages, if they have been wrapped in plastic.

Yes, it's probably true as you say when I start to think about it will try to isolate the last part in the ridge then fire up some heat in the floor.
