Window sill height 130 in the bedroom / study?

1. Yes, we are aware of the projections and recesses and will definitely seek the help of a friend who works in that industry.

2. Theoretically, you could mirror the rooms, that would probably work, but then what about the parapet heights on the south side of the rooms...

Well, I'd say the parapet height of 130 is seen more often on houses, so it can't be that bad... of course, where it makes sense... for me, it makes sense in the bathroom. Honestly, I wouldn’t know where else to set a parapet height of 55.

We have also noticed the issue with the doors... the utility room... we just wanted to go directly from the garage into the storage room or kitchen. The garage doesn’t get an adjoining room anyway, it was only drawn here fictitiously. The garage is only equipped with a door to the garden and into the house. The bathroom already makes sense with two doors opposite the children’s room, doesn’t it? And always having to walk around from the bedroom is also annoying. The storage room is under the stairs, I wouldn’t know why I should leave it out?

the various projections and recesses between the ground floor and first floor mentioned by @11ant: I find them visually appealing, but they do cause significant additional costs and are a potential weak point if executed poorly.

I would even go further and say (or rather have already hinted): I almost expect that the additional costs (but not the extra price) will be attempted to be offset by poor execution. As a motive, I simply suspect "fear" of otherwise excessive simplicity (or such "reasons" as the dogma of a certain sofa-TV distance, as marked the beginning of the R.Hotzenplotz disaster ).

Yes, we are aware of the projections and recesses and will definitely enlist the help of a friend who works in that trade.

In the building inspection trade, or what is meant?

yes exactly he is a civil engineer and expert

A very bold option for the east side... but we actually quite like it... you can just ignore the smokey eyes in the west.
