It’s not rare in a family that two children share one room, so not everybody has an own room. Commonly it is not a problem until they are 4-5 years old, even if they have different sexes. But after an age the children desire an own snug, in the case of a boy-girl couple it is more urgent to solve the separation.
If the size of the room is big enough, the separation can be solved easily with placing some wardrobes in the middle of it. Half of them with doors facing to one side, the others facing to the other side. This way both children will have enough storage space. The back of the wardrobes can be wallpapered, even with a unique wall-poster, fit to the style of the kid’s room.
In the case of a smaller room, the room separator could be a curtain, for example. Fix the curtain rod to the ceiling and choose a fabric which has weight to avoid the moving by draught. Panel curtain is perfect for this also.
Another solution is a unique partition panel, which is only one-two centimeters thick. Made of cut MDF sheets it lets the light through but separates the space visually. It is fixed to the floor and the ceiling also. The fixing can be a rail-system, this way they are rollable beside each other, with this the two areas can be united again.
If the room is really very small, let’s paint it with two colors (fifty-fifty) fit for the taste or hobby of the two children and decorate them separately. Although the room remains common, they will feel that part one of their own. If they can compound in a common color instead of the two, it’s much easier.
In the case of a high ceiling, the problem can be solved with a loft. If there is enough space for only a bunk-bed, that part can be split into two with painting the wall two-colored horizontally beside the bed. The turned/offset bunk-bed levels provide bigger separation feeling for the children.
