Floor plan design single-family house 150m²

I would omit the wall in the utility room entirely, not just shorten it. If you build a solid partition there, a new electrical appliance or new shelf might no longer fit, you’ll be restricting yourself. I would plan a small cabinet wall/kitchen unit where you can neatly store supplies and cooking utensils. Best regards in brief

The kitchen is 4m wide and if you plan a passage of 1m at the top and bottom of the kitchen island, then the kitchen island can only be about 1.40m wide.

Best regards
Sabine

Minus plaster and possibly air behind the kitchen unit.
The lower passage at the kitchen block is really too narrow, you can already see it in the drawing: if there should be a tall cabinet (oven/fridge) there, it will be too tight.
The tall cabinets should definitely be located between the windows.

Brief greetings

I fully agree with my three predecessors, this partition wall is at least useless. According to the definition of my "faction," this separation makes sense only for a pantry turned into a HAR, but for use as a storage pantry, even without the room being that narrow, the disadvantages would outweigh.

By the way, I also find it disturbing in the façade image that you have not yet implemented my suggestion to uniformly enlarge the windows to 1.26 m (because of the windows directly above each other with a 12.5 cm width difference).
Regarding the adjustment of the roof pitch of the dwarf gable, a tie vote would probably be found in a "vote."

The partition wall is constructed using drywall and was not planned as continuous. However, we would only install it afterwards once everything is settled and it is clear whether the wall makes sense.

I really overlooked the width of the windows. I also no longer had the roof pitch in mind. I will have a comparison made.

I really overlooked the width of the windows.

In some places it's hardly noticeable, but: where 113.5 and 126 are directly "stacked" under each other, that would have really hurt me when drawing the side view.

I also no longer had the roof pitch in mind.

I would make the pitch of the main roof and the return the same. But that's a matter of taste and as I said, I expect about the same frequency for the opposing opinion.

Um, just by the way ... I only just noticed this: why did you discard the idea of reversing the direction of the stairs?
