Hello,
we are currently considering building on my parents’ property, if we can obtain the necessary permits (building permit / planning permission). We would like to build a modular house. The problem is that the plot, where we plan to build, is on a very steep slope. Therefore, we thought about using steel support columns like those shown in the picture as a foundation. However, we have no experience with this at all. I can’t find any information on Google. What are these types of structures called, and what should be considered, or what does something like this typically cost? I hope someone here has some knowledge on this:

Unfortunately not, but at first glance, I see a rather substantial architect/structural engineer fee and a lot of challenges with the requirements for thermal insulation.

That's exactly what I’m worried about... Are there any other cost-effective options for building on a steep slope without having to completely excavate the entire hillside?

Yes. Make a virtue of necessity and build a floor into the slope, since the soil has to be removed anyway. This way, you can create living space there and save an entire level "above ground."
After all, that is the real appeal of a hillside plot. Of course, it’s not exactly cheap.

"other options" implies that what is shown in the photo is actually a viable option. But it is not. If these supports were really part of a pier foundation concept, there would also have to be a rocky subsoil. In reality, they are more likely just visual spacers between what appears to be a floating house and its buried foundation—they cannot replace it. This stilt gimmick probably costs about as much as the structure above it at the shell stage.

It’s more likely that a snowball would be an effective fire starter than that cost-effectiveness and an extreme slope go together.

What do you mean by extreme? Please show a photo or measurements.
