You will need to talk to an architect or perhaps a glazing vendor who specializes in curtain systems. They will likely provide the shop drawings necessary. Curtain systems are not something I'd attempt without help if you aren't an architect. There are too many variables, too many different ways to go, lots of options (storefront, spider, etc).

I would say a single sofa is most comfortable for sitting and It can transform the interior of our home. Recently I had ordered one single sofa from Oriental Creativity at a very good price. You can check this design. I am very satisfied with the purchase.

Hi Rupal, Thanks for your suggestion. The layout is as attached. I cannot move the door which is opening into the balcony. The other door is the room entrance door. Unfortunately I cannot change any of the doors though I agree sliding would be nicer. Would would recommend in the current setup? Thanks

Vinay, Since you have hired a professional, not sure how much of below will make any sense. This is a tall-boi room and the windows and doors height add to it. You have quite a good exterior view with surrounding greenery but the messy grills have kind of killed that view. You may have to always use sheer to hide them and coupled with earthen colored curtains. Plain bland white walls is another thing you may want to reconsider. Without going into too much details, a clean contemporary look for this place would be best suited. The ceiling lighting doesn't seem sufficient for a 14*15 room and I feel there is too much of wood on the ceilings even in the other parts of the house. As of now it looks like a transit place and glad to see this being made a permanent home. Will be eager to see the end results. Thanks Nitin Cornerstone Designs, Bangalore.
