Window section in steel construction

[Carlia]

The start of construction for our long-awaited house is planned for March next year, so now we're in full swing planning the appearance, layout, size, etc...

What we have already decided is that part of the house will consist of a large window section (width: 8m x height: 6m). To maximize the light intake, I believe a steel structure would be suitable, similar to those used for office and warehouse buildings.

I'm now wondering if anyone has experience with this type of construction? Any tips on suppliers of steel structures for residential houses? Since I plan to build the rest of the house with lightweight concrete (ytong), I'm also wondering how best to "connect" these two building materials? Anything to consider?

All tips, pictures, ideas are welcome!

Any particular reason not to have an aluminum part as usual? e.g. SAPA

No, not really. The only requirement is to maximize the window area.
This is exactly the kind of tips I was looking for. Thanks!

Does anyone have any approximate price information on aluminum profiles for the surface mentioned above?
What advantages does an aluminum construction have compared to a steel construction? If I'm not mistaken, steel is a stronger and stiffer material.

I can't comment on the price, but I have never seen anything like this made of steel actually, however, on really large glass sections, there might be a steel beam as a fastening for the aluminum section. But for such small sections, you shouldn't need a steel beam just for the sake of the glass anyway, but maybe for the bearing capacity of the wall otherwise?
