Reclaimed wood ,use pallets you could take apart and nail them up .Could be free if you look on Craig's list for free pallets

Well I'll try to make a 3d of the room and upload it. But that will take some time. Thank you :)

you could always use any glass top table with steel frame and put a matt finished steel tray arranged with some metallic miniatures or candle stand or spray paint some wooden table with metallic paint and give an oxidised look.

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!
