Manvisudan, I'm not sure what you mean. The walls above the sofa? If so, I think your should go with the richness of Indian art -- something like this wall hanging would be beautiful. I'd hang it horizontally. Look around for something that picks up both the lavender colour of the walls and the red of the carpet. It could be a rug, or a printed or painted cloth. Mount it on a rod and hang it with the lower edge about 18 inches or less above the sofa. (India is probably on decimal? 45 centimetres or less. Whatever feels comfortable to you.) Otherwise, look for those wonderful wooden wall art carvings produced in India and other countries in the east . You could hang one big one, or three small ones in a row.

Here are some photos that may help you. You have the ceiling height to have a nice heavy rod just above the top of you window that could run the ceiling width. That will give you the space to draw curtains back to expose the entire window. I highly suggest that you work with a designer. A good designer has access to literally thousands of fabric choices and will be able to help you in selecting the perfect fabric and design for your room.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

Cornerstone Design, Thanks for your response. The electrician and false ceiling folks I've engaged are very competent, and are going to take care of installing the ceiling fans (of any type or kind I buy). My only task is to find and procure appropriate fans. Regarding the loss of about 10" due to the false ceiling: I only did a simple rectangular tray drop design for lights (approx 4-6"); however, the original ceiling was not straight, and approx 2-3" extra went in straightening it at the tray edges. Since the ceiling seems (perceived) low, I do not want to make it look lower visually. I am looking for fans that will be as close as possible to the false-ceiling without effecting its sweep functionality or energy efficiency. Any suggestions on where I can get good ceiling fans in Bangalore (all brands and varieties under one roof)? I would also like to see/consider the options you've mentioned (special fan like flush fan or ceiling swing fans). Where can I see/procure these in Bangalore? Thanks!
