Hi,

You can have a partition using sliding doors made up of glass and cover them with curtains.It will not darken ur room and u can slide it when u have guests.

The following tips are useful to add a temporary partition between dining and living area.
1. You can install folding partition wall which has roller/wheels at the bottom and can be easily removed when you want more space.
2. a) You can also provide ply board or particle board or block board partition wall with hard wooden base. Mild steel flat iron hold fast should be fixed at both ends of partition walls on both sides. The partition wall should be fixed with both ends of the walls by tightening the screws in wooden plugs which are already fixed in the walls.
     b) The partition wall should be in 3 ft pieces in length and these pieces     should be joined with the help of hinges.
     c) When you want to remove the partition wall fully, loosen hold fast screws to remove partition wall. 
     d) If you want some portion of the partition wall to open temporarily, you can fold the partition wall which is in pieces and joined with the help of hinges.
    e) The wall pieces which are joined with the help of hinges are also helpful to store in a minimum space when the partition wall is not in use.
