Some of these ideas range from the use of physical furniture to half walls with columns, bookshelves, curtains/fabric and even lighting system.
These walls are installed on the outer side of the existing wall and run from the ceiling down. If you are looking for natural look and feel, slate tiles can be used and in getting more creative, you can arrange family and personal photographs on the wall, in both directions if you want. You can also place decorative pieces like vases and sculptures within the spaces in the wall. It makes an elegant look at the end of the project.
Apart from forming barriers which are needed for creating individual spaces, the curtains also allow light to come through from other parts of the room. In getting more creative, you can add embellishments to the curtains, especially if you desire a funky look.
