ᐅ What is the most cost-effective type of shell construction?

Hello,
I want to start building this year. However, I can’t find any website that compares the costs of different types of structural work. But isn’t this actually a fundamental aspect?
Of course, I am aware that certain construction methods lead to higher follow-up costs (such as greater insulation effort, more work for the electrician, etc.) than others. Therefore, a general statement is probably hardly possible.
Nevertheless, I am considering having a solid prefabricated house built (walls made of Liapor, cast in place). The question now is simply: how much more expensive or cheaper is this method compared to conventional masonry construction with Liapor, brick, or Ytong block? How does it compare to a prefabricated house? Which is more cost-effective?
Perhaps someone knows of a website that compares these construction methods. Unfortunately, I haven’t found one yet.
Thanks in advance for your help.

In my last post, I mentioned that I am not a professional and am trying to gather reliable information here. Also, it’s not about how many times you have done something, but at what level. If you build the same poor quality 1000 times, you haven’t made any progress, right?
If someone claims "suddenly 30 percent higher costs because of the architect," I have to doubt such a statement, despite my limited expertise. The architect would appear very untrustworthy, and I believe they have failed in their profession. When precise requirements are communicated, I also expect a precise price. That price will definitely not be one third (30 percent) higher. Therefore, I consider this claim to be complete nonsense, and the same applies to the person making the claim.

According to my research, the most cost-effective structural shell was achievable with solid wood elements made from waste timber, as there was minimal offcut waste and no insulation required. After that, infill systems come next, followed by large-scale wall panels bearing well-known brand names.

I prefer to stick with the German oak...
Just inserted as a quote from a construction law forum:
The comparison should be made between the ratio of the calculated costs to the realistic costs at the time the cost estimate was made (depending on the work phase).
Since the cost calculation must become increasingly accurate as the construction progresses (see above, II DIN 276), the tolerance limits also become smaller. Exact percentages cannot be determined due to the large number of individual case rulings in the case law. However, as a rule of thumb, the following still acceptable tolerance values can be assumed:
Preliminary cost estimate: exceeding by up to 30 % (Higher Regional Court Stuttgart, OLGR, 2000,422)
Cost calculation: 20-25 %
Cost projection: 10-15 % (Higher Regional Court Cologne, BauR 2002,978)
You’re grown up already and can look up the case references of this nonsense yourself, right, interested party? I wish you a pleasant life.

I asked because you are acting as if you know everything.
If a professional tells you that additional costs will be around 30,000, you can trust that. These are based on experience! Whether it ends up being 25,000 or 35,000 depends on the local conditions and your individual requirements.
For example, if your house is 40m (130 feet) away from the nearest sewer or power connection, costs will be significantly higher than the average distance, which is probably around 10m (33 feet).
Another example: a sloped site. The cost of the house itself is probably the same whether it is on flat ground or a slope, but the additional costs will be higher.
Since no one knows your exact wishes, only rough estimates are possible, and an approximate amount of 30,000 for additional costs works well without going into every single detail.
First, take time to inform yourself before spreading your lack of knowledge here!
