I have seen a couple of your posts where you advocate for concrete walls that you construct with:
Pre-fabricated concrete wall, (50 mm concrete, 200 mm insulation, 22 mm glespanel, 13 mm plasterboard) plastered exterior with chosen texture costs: 2210:- per meter + VAT
Where do you buy these walls? Do they have a website where one can check how it's built?
What kind of roof do you have on this concrete house?
It is appealing that it is more maintenance-free than wooden houses... (I have experienced changing the panel on a small terraced house once and repainting the facade on a smaller villa)

We chose concrete for that reason, maintenance-free for many years ;D
The walls are made by a subsidiary of Finja, "Östra Grevie" in Vellinge.
The house has 1.5 floors, so only the exterior walls are made of concrete, the rest is wood. The roof with concrete tiles is, as usual, a wooden construction.
We have also chosen to make the gables of the dormers in concrete, but the sides can't be done, so they will be in wood, which will be plastered afterward.
A "normal" construction is to make the entire dormers in wood, but we complicated the construction a bit because we thought it looked nicer 8)
The link is www.finjabetong.se go to the dept. prefab.
Here is what it says on their website, under Wall Elements,
Customized facades delivered as solid or in sandwich construction with intermediate insulation.
The flexibility in production is high and therefore the elements can be manufactured according to your wishes.
And it’s true! Our construction wasn't easy but they do as we want.

It is not lightweight concrete, it is concrete elements. They weigh tons!
Y-tong was much more expensive. Building with Leca isoblock blocks was more expensive, would take longer + the cost for the builders. Additionally, you have to plaster the entire house at a cost of about 200,000!
These walls have a very good U-value (0.18) very good insulation. Easy to assemble, you just bolt them to the foundation and weld on top with the included metal pieces. Then you seal the joints.
Building with concrete blocks instead of wood was not much more expensive. We calculated that for our house (230m2), the difference is only 30,000.
So there were several factors that influenced the decision.
Being able to build a stone house without going broke
The simplicity of building, the U-value, and the fact that they are already plastered, you just need to paint.

What is the maximum length of wall elements they can make?
The floor plan we have found and would like to realize has the longest wall at 12m internally.
Are the wall elements freestanding that you've taken, or do you have some frame that you erect everything against?

Oh! have you considered that it needs to be transported too 8)
The longest wall elements they can make and transport without breaking are 9 meters. The height is believed to be 285cm - 290cm, ours are 285cm, the ceiling height inside is 260cm.
Look where you can divide the long wall!
Freestanding walls, they have a steel reinforcement built into the wall. Assembled like a deck of cards bolted to the foundation, which is a special type of foundation for concrete walls, welded on top, joints and then it's done!
You have some pictures on Finja's page on how they assemble!

It is a slab on the ground, but it has much more reinforcement than a "regular" slab on the ground for wooden houses.
Leca beams are used for the foundation, reinforced in a special crisscross pattern, making them withstand much more load. Then, the entire edge beam is reinforced on the inside before pouring the slab. You can see how it's done on my website; I have added pictures of every detail. Even the label on the edge beam (foundation beam) ;D

Yes, we Swedes are significantly more exposed to radiation than most other peoples... Our bedrock has relatively high radioactivity. Additionally, if you live in a stone house, you are obviously exposed to even higher radiation doses than someone who lives in a wooden house.
I actually don't know what kind of stone Ytong, Finja, H+H Celcon, etc., use in their concrete manufacturing. It would be interesting to know!

In our case, we don't come into contact with the concrete ;D
The concrete is only 5cm on the outside, followed by 20cm foam insulation on the inside with paneling, masonite, and gypsum boards.
The entire construction inside the house is made of wood, both load-bearing interior walls and all other walls.
All the floor structures are made of wood except for some iron beams that will support part of the construction.
It's not the same as having a solid concrete wall.
We asked about this before we decided to build according to this method. There is no risk of radiation.

I visited your website and saw that you had an issue with the fitting on one side. What was the problem? Was it manufactured a bit too long?
Otherwise, the assembly looked quite smooth. It will probably look good once the concrete is painted as well.
Another question: Do you know if it's possible to splice the wall to get walls longer than 6m?

There was a part of the gable that was 15cm too large on each side. They had to cut it with a concrete saw to fit it. It went quite smoothly. All additional costs will be paid by the company that made the walls.
Yes, it went very smoothly and quickly (2 days) to put together all the walls. What took a little more time for perfect adjustment was the corner decor, which is also made of concrete.
The longest wall you can make is 9 meters. The reason we joined between the living room and garage is because they are two different concrete walls. The one in the living room is with insulation, and the one in the garage is 8cm of just concrete without insulation. I wanted a cold garage.
I think it will look nice when we put up the masterphased on the upper floor (the dormers) and plaster them with the same type of plaster as the ground floor.
Then it will be a choice between red or yellow ;D
