It's a children's space, so you have to pay more attention to safety, insulation, and so on.
We built an insulating folding door and a system door just right for that.

Each part has a different theme.
Usually, separate the space and use it for each theme.
If you need more space, you can fold the folding door as much as you need.

Kid’s Cafe is the most important thing as children are givering.
There may be frequent hand entrapment between the doors.
Rubber finishing between doors can help prevent hand injuries.

Use translucent windows rather than transparent windows because they are toilets.
You can check the number of users inside the bathroom.
Polyamide insulation provides excellent insulation and tightness.
