Regnauer is a good tip, I had also thought that there would be a suitable wavelength in terms of style.
no - I couldn't think of anything more creative
For me, this search did not lead to the goal...
We call something like that "Diwan"
... or a chaise longue would also be quite nice to me
But it could be that the brick thickness is meant?
Possible. For bricks, I would expect 49, 36.5, or 24 cm; 50 or 25 would rather be aerated concrete plan stones. I suspect the 37 here as the sum of 25 cm concrete plus 12 cm insulation stuff. But I had also formulated my question imprecisely and partly aimed at the aspect of what the core building material is and whether it is supposed to be used monolithically. And sometimes there might also actually be different stone formats in AT than in DE or CH (?)
Regarding the L-floor plan: the concerns probably revolve more around the standing height area, in which one could build out – by the way, you can’t borrow amateurism – but in my opinion a floor plan shape should rather result naturally than be pursued, otherwise I would see the risk of a shift in priorities.
