ᐅ Floor Plan Feedback Single-Family Home 140 sqm Two Full Stories

Hello everyone, following my last post about costs and so on, Ant11 suggested that I start with a floor plan here for evaluation. This plan has now existed for quite some time with a few minor adjustments, so the ideas have not changed. I’m looking forward to some feedback.

House Design
Who designed it:
- Initial draft by architect then adjustments with builder/architect
What do you particularly like? Why? Utility room with separate door (mudroom), large pantry
What do you dislike? Why?
Price estimate according to architect/planner: 433k
Personal price limit for the house, including fixtures: 500k
Preferred heating technology: air heat pump and central ventilation system

If you had to give up, which details / extensions
- Could you give up: if push comes to shove, the separate door for the utility room or the pantry could be omitted
- Could you not give up: guest WC with shower

Why did the design turn out the way it did? For example:
Build as small as possible but as large as necessary. The plot becomes wider toward the back.

So, this is a draft after a consultation appointment with the architect. It was then revised again with the builder.
We want a functional home that works for 2 adults and potentially 2 children (1 currently). In addition, we have a dog, but that obviously adapts too (the mudroom is also designed for this).
Home office is generally possible and planned. First, we have one child’s room reserved and intended for this purpose. Afterwards, the office niche or the bedroom upstairs. We don’t need much except a quiet place to work.
If all else fails, the pantry will become the office (possibly then accessible from the hallway).

The upstairs bathroom is somewhat elongated due to the narrow building footprint and straight staircase. The washing machine and dryer are shown upstairs and are planned to be there. There are also connections in the utility room. Otherwise, the space upstairs or downstairs will be used for storage.

I look forward to your opinions.
