From commercial property to a bungalow

Hello ktb,
I really like your idea! I hope the OP does too. :)
Nevertheless, I would place the entrance to the master bedroom as Neige suggested. This makes the path to the bathroom shorter and, in my opinion, also somewhat more hidden and therefore more private.
A big question for the OP is how much closet space she needs in the bedroom.

I find the loss of parking space in Neige’s idea too great! If there is a third child, there would also be no storage space left in the third child’s room.

In my opinion, the painting of the pantry can be relatively well balanced by the closets in the hallway.
But it would also be good if the OP could determine for herself how much storage space (shelf meters and depth of the shelves) she actually needs for the supplies.

Tip for the OP: Try to furnish rooms somewhat realistically right from the start. Your pantry design could, for example, be outfitted with shelves 20 cm deep along the long wall. But then there would be less than 80 cm of space left for walking through — when carrying in a crate of drinks, you always scrape along the wall; both the shelves and the passage would be too tight.

If you — like me — lack the necessary imagination for the rooms, take measurements in existing rooms. Even during remodeling, a visit to a model home can be helpful to get a sense of room sizes.

oh yes, regarding the entrance situation: can't the slope be compensated by steps or a small ramp to get the front door directly next to the guest WC after all? Although that would bring strangers a bit closer to the living area because you are immediately standing in the "real" hallway. However, that way the office could be enlarged again – how much space do you need in the room? Receiving patients sounds to me like it requires more space...?

I also had concerns about the loss of storage space with my suggestion. If the shower in the front area is removed, you could still use the niche that could then be created in the bedroom, but does that make sense? You could possibly store supplies in the little room that Kerstin marked in front of the kitchen. Well, these are just some considerations.

.. I had the same thoughts ... that's why I asked the question about the entrance in the middle area.

Yes, the way from the master bedroom is a bit further, although at night you can easily use the guest toilet and definitely also the shower there.

I can also imagine that in the initial phase in Child 1 there is simply the marital bed and possibly a seasonal wardrobe, then you are also closer to the 8-month-old child.

I could also imagine the storage area, where on one side I have the washing machine/dryer and on the other side still 2 shelves, closed continuously with large sliding doors. Behind it, there could then also be space for a large freezer, possibly some garden equipment, etc. Supplies would be much better compared to the 40 cm deep cabinets. Could be cabinets from the Metod series by Ikea. Then it would be 4x80 cm or so.

To ensure Sigi's access option to the master bedroom, I have rearranged things a bit now.

And also sketched how I imagine the area with the washing machine/dryer/freezer cabinet with sliding door.

Additionally, I showed that Child 1 could also be the master bedroom with a 3 m wardrobe. Then only the current season's clothes would go there, and the remaining clothes would be stored in the parent/guest area.

Or just a different redistribution of the clothes.

I would like to point out once again the unresolved issue that the planning upper slanted wall is a boundary structure and therefore cannot be suitable for windows!!! Until the original poster addresses the question, as well as whether skylights are possible, any further planning is simply a waste of time.

Regards
