Can you recommend floor plans / houses in Bauhaus design where you say: "Wow! This is a benchmark"?
In my opinion, you can’t really say that so abstractly, because good architecture always takes into account the needs of the plot and the respective builders (in my opinion, also in that order).
Similar to your approach, for example, I would mention Gnosa Architekten SB 16 (plans for this were published in Cube Magazine Hamburg). That’s just an idea, not a "Wow" reference. The garage is still missing there, and the plot and building are somewhat larger as well. Too much "Wow!" is not always good for everyday life.
Personally, I don’t really like the white flat-roof boxes (or only like to look at them but wouldn’t want to own one, and as a North German, I would also get annoyed about the green algae-covered facades after a few years) and prefer a visually clear edge and clinker brickwork with a gabled roof without eaves. That, however, is highly subjective.
A nice view effect, for example, is house Blankenese by Bub architects (plans can be found in the appearance with Schöner Wohnen). That of course probably also applies to the price tag. We ourselves took inspiration from Baurmann Dürr, residential house Kirchfeld, from the offset corner levels and clad it with bricks, mirrored it, rotated it, and adapted and slimmed it down according to our needs, see above.
For inspiration, browse through the common architecture magazines online; you will find a lot to marvel at (and just as much staging). In Bavaria, there is also the "BR Traumhäuser" series available online in the media library, which is also very entertaining.
