Floor plan 160 sqm single-family house - improvement ideas?

I just don't really know how to get from working through to the desired floor plan...

As nonsensical as it may sound: the shortest connection here is to first create some distance in between. That means during the phases of your internal confrontation (reflection) you should put the catalogs away for three to four weeks (just the intention not to touch them is not enough: the ritual of putting them away is part of it).

or should I just leave it

For the current phase, yes, for now.

Phew... move the sofa...

House Design
Planning by: so far own design, based on model houses and catalogs.

Price estimate according to architect/planner: no estimate yet
Personal price limit for the house, including equipment: 350,000-400,000 (plot available)
Preferred heating technology: district heating

The current design is based on various model houses and manufacturer catalogs. What I liked in the model houses has been incorporated into the floor plan. For example, bathroom layout in T-shape; shower and WC thus hidden on left and right behind the T. Unfortunately, my current drawing tool does not allow furnishing. I therefore have to print the plans and add the furnishings by hand. A furnished floor plan will follow.

I think the floor plan shows the intended rooms and the desired space requirements.

I hope this now provides a better working basis!

Better, it would be even better to insert that into post 1 of this thread (if that's still possible, but it should be since recently), then it can be found more quickly. And, a site plan of the property is missing, preferably oriented to the north and with a few measurements.

The thread is slowly becoming interesting after all. What does the property look like? A site plan would be really nice. 350 to 400 thousand - with a basement that will be tight. Do you really need it? What is supposed to go in there?

Roof pitch (25-38°, dormers etc. only from 35°)

The specification was probably made by someone very thorough

Floor area ratio: 0.4 (general residential area)
Plot ratio: 1.2 (general residential area)

That would suggest possibly three full floors (?) – do both values refer to the same building plot?
