Floor plan design with some requirements - ideas?

Hello,
regarding a later separation: the staircase upstairs only has a knee-high wall as a railing and no full wall so that more light comes to the stairs and the narrow hallway upstairs looks a bit more spacious. A separation is therefore only really possible if a front door to the apartment is installed downstairs in front of the stairs, right? Where would you suggest placing kitchen connections? Probably cheapest in the study room against the bathroom wall, but that is not a really nice place for the kitchen.

I probably have to give up on separation in the living area. Even if the children's room is reduced, it is suboptimal: Thanks for the visualization, kaho.

The floor mat is not intended for therapies but as an additional place for our daughter to stay. She does have a therapy chair, but sitting becomes tiring over time, so she repeatedly lies down as well. She has an approximately 1m high surround on the side and at the head end, with toys hanging above her. That is her retreat and place to feel comfortable. It would be great if I had a good view of her (possible only from the front, i.e. her feet, because of the surround). I also need power for this because there is a light strip inside. Since lifting it from the floor is getting more difficult, I want to put her play cave on a pedestal soon. It could already have wheels but will probably find a favorite spot in everyday life.

The children's room on the south side fits better so that she is closer to the living area.

I would prefer a separable hallway in case we need a care service someday. Then if you want peace and quiet, you have another door to close and can talk more freely. At night we would then possibly sleep in the guest room.

What do you think about installing a slanted two(?)leaf door?


Thanks to you all for your hard work helping!

But I consider the slanted door extremely unsuitable for wheelchairs.

Find the sliding door from the 1st plan best. That way you always have access to the door. What do you do if the wheelchair is ever standing in front of the door?

What do you think about making a slanted two(?) wing door?

Nothing.

I like the sliding door from the first plan best.

I agree with that - what would you like less about it?

In order to fit the couch there, the wall in the hallway where the original kitchen unit and the children's room wall behind it were must move downward according to the plan. However, then there is no space left to open the sliding doors on either side. I see no problem with the children's room. It will either have a normal door or the sliding door will run inside in front of the closets. The door to the storage room under the stairs should preferably still open outwards to be able to use the room reasonably well. However, this means the sliding door to the living room will no longer open.

Then we just have to come up with a nice folding door solution here.
Or like with a wardrobe, the two doors (hallway and storage room) slide one behind the other as sliding doors.
