I have a small one bedroom apartment and I need to take part of the living room and make it into an additional bedroom.I was wondering what my options are and what is the cheapest option I have with regards to keeping a good amount of privacy.Thanks for any help.

You didn't say if you own or rent. If you own you can do things that a renter can not.

I rent the place so building anything elaborate is obviously out of the question.Thanks for your reply any input...

Let's see here. Cheap, fast, no damage to the ownere's property, provide privacy.

Hang a clothes line and throw blankets over it.

Go to ******* and buy a tent to set up in the living room.

Build your self one of those accordian folding, self standing room screens.
