I'm also interested to find out more about this.

I've seen the partition walls in IKEA which are quite thin but solid.

Any feedbacks?

If you're really a hardcore DIY person, you may check out some tutorial videos online which offers step by step methods on constructing these type of walls.

It looks quite simple as these are professional handyman doing it. But I think I'll screw it up especially with the alignment of the frame and I don't want a crooked wall.

Even sourcing for the material is a bit difficult for me.

This is good:
