Hello everyone,
We are currently thinking about how to cover our protruding plinth (first floor with a 49cm (19 inches) Ytong wall on top of a 30cm (12 inches) concrete basement wall). What options are available for this?
Attached you can see a cross-section of the components with their thicknesses:
The red arrow points to the edge that still poses a problem for us because we don’t know how to cover it. With the houses we know, it’s the other way around: the plinth is recessed and the facade slightly overhangs. But due to the thick XPS insulation and the concrete wall located centrally under the 49cm (19 inches) exterior wall, this edge extends at least 4cm (1.5 inches) in front of the facade wall. Is this an issue?
Could this be solved with a metal flashing like in the picture below?
Is the usual approach to apply a mesh tape onto the perimeter insulation and then plaster or alternatively clad it (stone, metal, something else)? And then cover the protruding “problematic” edge with metal flashing like shown in the photo? Or are there other alternatives for this?
It is important, of course, to have a drip edge at the main wall (facade) to avoid moisture problems, correct?
We appreciate any advice and tips.
Sunny greetings to all forum members from Baden-Württemberg

Of course there is a planner involved, but nothing has been finalized yet. This was only discussed during the last meeting on Saturday. Ultimately, the structural engineer has a major say regarding "where and how strong the concrete basement wall beneath the 49er Ytong wall must be."So, the problem doesn’t even exist yet!!!??? Well, then he should just redesign that crazy basement wall projection away, and the problem won’t occur in the first place.

No, we have not started yet, so the foundation topic came up before construction began.That’s a good start! What does the architect/site manager say? Attached is a sketch that seems more logical to me:
