No, you can't say it that easily.
There are "cheap/low-cost" providers and high-end providers in every type/segment of house construction.
We build using timber frame construction, so I know a bit more about it. There are mass low-cost providers, mid-range providers, and high-end providers who all install materials in Biööko+ (I'll just take that ;)) – with the corresponding costs.
Therefore, in my opinion, the type of house construction can be clarified with two options: Engage with the subject professionally and decide what you want! Or set a standard for the floor plan and equipment and obtain and compare offers from possible providers.
Comparing offers is another matter entirely and incredibly complex to compare alongside the equipment for heating, sanitation, electrical, interior design, external services, delivery times, and so on and so forth ...
