Yep, you have just as many. (<- that was meant ironically)
Just over 2m are still there. Heating and controlled residential ventilation already marked. The utility room/HAR is at least 8.5 sqm, even if a small part of it is under the stairs.
Strange, nowadays people place the washing machine and dryer on a pedestal because it's easier on the back. In your case, it's not just the back but also the head that hits the stairs
At 1.75m above, it’s maybe 1.55m at the bottom edge. You can still put those machines on a pedestal there. Of course, we will make sure they are flush with the wall above or possibly set forward by 5cm, so you don’t hit your head.
Yes, then you can use it for the washed laundry – there’s no space for that in the utility room, which serves as the “dirt lock hallway”.
Maybe the laundry could also dry in the study. Or in the dressing room. Or outside, or in the dryer, or...
Sorry, but I don’t think much of the idea of a “small utility room as a passage hallway” and the stair niche as a laundry area at all. The stair space is valuable, no question, but not for appliances that you operate and need valuable shelf space above because it’s not available elsewhere.
The passage from the utility room to the garage is downright brilliant. Not to forget that a lot can then also be stored in the garage, at least that’s how we have seen it.
And I have to be honest: I get the feeling that no household management is really taking place with you at all. I already doubted it with the kitchen back then (Grym and his wife only go from the front door to the kitchen twice a week, then the topic “the living room is the main living area” (okay, not every couple or family is actively engaged with hobbies and garden, but just plops down on the couch immediately, probably my somewhat subjective judgment), but now the laundry ritual... So I have (and I don’t wash often) for a two-person household two laundry baskets that are always filled and standing around in the utility room, then sometimes two piles of sorted laundry on the floor (e.g. whites and colored laundry), then washed laundry that may not go into the dryer... and then my husband comes through the utility room, right in front of these machines, with muddy shoes...
For me, household was and is certainly not the most important issue, but – or precisely because – it has to work. I don’t see that here.
We don’t have a garden yet, but it should be low-maintenance in the future. So first a large terrace area, lots of lawn, and then maybe some plants that cope with the natural climate of our climate zone, i.e. don’t need artificial watering and grow on their own. I don’t know if such things exist.
Our hobby at the moment is our little daughter, no time and desire for extensive household chores and I just went shopping again on Friday for almost 200 EUR... yes, I really hope that doesn’t happen more than twice a week, rather less often. Shopping is a huge waste of time. And if I do go, everything possible has to go in.
The laundry basket is supposed to go into the bathroom, after all that’s where you take off your clothes. I could well imagine having two laundry baskets there; there is space after all.
All in all, you have to draw the line somewhere. If for this 157 sqm living area layout the biggest problems are the utility room/HAR with 8.5 sqm (not completely usable, but partially with “sloping roof”) and maybe the issue that possibly people coming from the guest WC and people newly entering the house at the front door could run into each other, then I find that acceptable.
Or are there concrete suggestions for improvement without questioning the complete structure of living/dining/kitchen at an angle, study on the ground floor, WC with shower on the ground floor, utility room as passage to garage, placement of the garage and orientation of all rooms, etc.?
