Hello everyone,
After reading a lot here and planning for three months now, I’m trying to get some help.
The plot is complicated, maybe a bit narrow to also fit a separate apartment on the ground floor.
We are unsure how to “split” the plot.
Who should get the west or east side?
Which street should the house face?
The 5.5 m (18 ft) setback area on the north side suggests itself as the driveway/parking area. Also, no one wants a north-facing garden.
We all want sunlight somehow, but with further construction progress on other houses (marked in red) and the low sun angle, hardly any sun reaches the southern area.
The separate apartment really only needs a sunny terrace (because mowing the lawn will get harder with age).
I’ve simply added the architect’s two drafts here.

Why not place the concrete point (CP) at the boundary? Wall panels and beams for load transfer. Also, no wall at the boundary saves space.

Because the 1m (3.3ft) distance must be kept for planting purposes.
Then at least car doors will only hit a hedge.

Wall panels and beam for load transfer.Well, how something is executed is up to the architect to further plan according to the original poster’s suggestions. I only have 24 hours in a day, after all.hanghaus2023 schrieb:
OK, but then that’s a different floor plan on the ground floor.Ah, now I understand. I rotated the staircase but didn’t take an updated screenshot.H

I have been experimenting a bit. Your building layout makes me wonder if a corner-attached mother-in-law unit, like the one used by @KingSong https://www.hausbau-forum.de/threads/meinungen-zu-unserem-grundriss-entwurf-erwuenscht.23977/page-9#post-224438, might fit well here.

I will take another look at the thread.
But always keep in mind:
Two roofs are also expensive / gable roof?
High built-up area (site coverage ratio 0.35)
