Recommendations for "Faschen" sought - nostalgic charm

With us, the plaster is thicker than the area of the [Faschen].

I am also interested in reveals. Is the relief achievable only with plaster and in one plastering process with the entire wall, or can you, for example, work on it afterward? Or is there thicker paint that can be used?

No, at least as a raised variant, this cannot be done with paint. I believe our mason implemented it with plaster beads and reinforcement mesh. You can also consider creating the reveals inward. In that case, boards are placed around the windows during the plastering of the facade and then removed again. Of course, only option 1 is possible afterward.

Chamfers are normally not raised, but rather flatter than the normal plaster and also smoother. But every plasterer knows that...

Exactly, that's how they are in the example image I initially posted.

Okay, then I colloquially classified that under Faschen. If it is raised, they are reveals, right?

I am also interested in reveals. Is the application only done with plaster and in one plastering step with the entire wall, or can you, for example, address it afterwards?

Personally, even with the same thickness, I would prefer a different surface texture – so probably reveals and fascias in a later work step. What is it supposed to be ( ): a colorful house with white collars around the windows? – I would find raised "old-fashioned" nice, as a natural stone imitation, and with a curved upper edge, for example.
