Instructables

Room Dividers and Other Space Sharing Devices

There are few instructables about residential space dividers.  These might permit folks to live more comfortably and economically. They could be temporary as well as permanent .
Could they rolll up to the ceiling ? Could they be flat against a permanent  wall until needed ? How important is acustic l privacy ?  Beauty ? 
Fire resistance and safety ?
If there are people who have thought about these issues or who have solved a space sharing problem, with some device or other, please post them. They are of no immediate concern to me or mine, but who knows in the future ?
