How do I build a partition in a studio apartment?
If you can afford wooden shelf units, face one one way and the other the other way and keep going, leaving a space to walk through if necessary. I did this for a room with two boys in it, and each one had two open spaces and two with a wall for cork board or posters. You can attach them with flat metal hardware so it can be taken down when needed.
I hope that helps.
My friend's daughter and boyfriend moved into a very small apartment. To split up the living room from the bedroom, the landlord used pallets as walls.
