If you have one huge room and would like to optically separate it, there is no better option than a sliding library from Woodface. The construction of the library can be moved freely through the whole width of the room, leaving you with an undisturbed perspective to the other part of the room, or creating a private sleep area.
Another option is putting the library in front of a wardrobe. This way it´s dominancy will be pushed, making the room more cosy.
If you have many books at home or files at your office, a sliding library is an optimal solution.
