Window connecting elements (wood, slate)

I am interested in so-called window-connecting transverse elements for my new build (can't find another term).

Here as an example, on the one hand made of wood and in the second image as slate panels.

Can someone explain to me technically how this is implemented in a construction method without ETICS and how the depth is compensated? Can the elements be attached directly to the outer wall and the rest is plastered, or how should one imagine it?

Thanks in advance for the answers!

Can someone explain to me from a construction perspective how this is implemented in a construction method without ETICS and how the depth is compensated. Can the elements be attached directly to the exterior wall and the rest is plastered, or how should one imagine this?

When this was still reasonably modern, times were different: before ETICS and before the Energy Saving Ordinance. It is possible to attach directly to the wall, but flush with the plaster practically means a correspondingly slim build-up. Are you "very afraid" that your house might look too "simple"?

When it was reasonably modern once before, those were different times: before WDVS and before the Energy Saving Ordinance

Correct. I see it every day when I drive to work in a residential area. Was that the 70s?

Are you "very afraid" that your house might look too "simple"?

Am I afraid? No. I'm just interested in how something is implemented.

Were those the 70s?

Until the early 80s, I would say.

Am I afraid? No.

I just meant, because with your house design I had the impression that you really wanted to bring "profile" into the facade.

I only meant that because with your house design I had the impression that you were trying very hard to bring "profile" into the facade.

The effort is there, but the reason is that I really like something like that. Whether we will manage to implement it, I don't know at the moment. Currently waiting for the architect's first draft.

Whether we can implement it, I do not know at the moment.

Since the Energy Saving Ordinance, even the smallest cantilevers are a "complicated act" due to the intermediate installation of a thermal break element. From my point of view, especially inexperienced builders are too afraid that their building might turn out too unindividual – whereas you can "articulate" so much with proportions and textures that profiling is often "unnecessary".
