Floor plan optimization for a semi-detached house of 150-160m² on a 360m² plot in a new development area

Do people do that? Different topic, I couldn’t quickly find anything on this: Do you need a study/guest room?

Yes, definitely. I am a teacher and we have family who live farther away.

2*86.5cm+110cm+25cm=308cm Of this, 26.5 cm must be deducted for the exterior wall.

Without flipping back or checking my drawing: I know that I mistakenly assumed 39cm for all exterior walls. And since, due to plaster, baseboards, door frame, and light switch area, I never take the actual number, your gross 2.85 is comprehensible to me. Sorry for the faux pas

No problem at all. I had already responded to your other post as well. But since I was a bit terse at that time and no longer had the ban on external links in mind, the post disappeared again ....

If you haven’t received a warning because of your external link, then it went well :)

Individual or even half centimeters only exist in construction plans.

By the way, this generally applies, also to wood-based instead of stone-based houses. A drywall panel is indeed an industrial product and therefore has a more uniform "layer thickness" than a wet plaster, but carpentered construction, like masonry, also allows a thumb width as a usual tolerance in level, plumb, water, and angle.

Is that what people do?

Not everyone has a convertible to drive the kids through a brush car wash *LOL*

Maybe I'll summarize again which points on the ground floor are still unclear:

[*]Collision-free door swing on the left possible with narrower WC door
[*]Possibly 5-10cm deeper wardrobe niche
[*]Design of the living room door and glazing: right/left/both sides
[*]Height and width of the partition wall between living and dining areas
[*]Possibly double spiral stairs
@ ypg: Can you show dimensions in your alternative drawings or is that more complicated?
