Comments on floor plan design welcome

Generally, I always find that a lot of value is placed on living spaces, but less on storage and ancillary rooms.

Sure? Don’t you browse the forum? I always advise it, it is also stated in the pinned mandatory posts... Your questions should be answered by that, your floor plan looks different if you follow the discussions...

Considering that heating, house connections (electricity, telephone, water), washing machine & dryer, second fridge and freezer all have to be in there and additionally a workspace for sorting and hanging laundry (clothes horse) and possibly ironing as well..... how much space do you realistically need for that?

Of course, you already consider that before the first sketch, where you want to wash laundry and store the dirty rubber boots. You plan replacement space in parallel. Large kitchen, pantry not necessary, utility room on the upper floor, freezer for essentials, small freezer room, further storage space needed.

Sketches are, by the way, intellectual property and meant to capture something temporarily. They can serve as a basis, stimulate thinking, and should be used for a fresh start. For this, one should know what they want. Here, one could then create two children's rooms under the roof, which later serve as guest rooms and hobby rooms.

For your listed requirements, it should be at least 10sqm. You can also move the closet on the right side of the dressing room in my floor plan proposal downwards, then you have a straight, light-filled corridor from the bedroom to the bathroom. Then nothing is convoluted anymore

So then I wouldn’t have any door left between bathroom, dressing room, and bedroom? Pagoni will be pleased, since his wife so likes to sit on the toilet in the bathroom and spread odors

Is 10sqm enough? There it is, my missing sense of spatial dimensions ( ) .... I would have guessed more, because heater 1sqm, washing machine, dryer, fridge, freezer each 0.5sqm, space in front of doors each 1sqm (would like an outside door), drying rack, etc. already take up >50% of the room as storage space.

We have no door between the bathroom and the dressing room and we don't miss it either. However, we also have no problem if one person is sitting on the toilet and the other is also in the bathroom. For more odorous business, we always go to the guest toilet.

You think about such things BEFORE planning. And the advice to see an architect is still the first priority here. This won’t work with you. It’s not possible. You have no sense of space, nor a sense of sqm, and your thoughts have no thread.
I’m out and will come back when an architectural drawing is posted here.

Of course, you can install doors. There are also ones with glass elements or made entirely of glass. I would only plan one door to the bathroom. I wouldn't need one between the bedroom and the dressing room. 10sqm would be the absolute minimum to still (roughly) be able to hang laundry comfortably. It always depends on the spatial conditions. The best thing is to draw in all the appliances you want/need to place there.
