You can use any seasoned natural hard wood like teak , sal wood etc. Another alternative is acacia wood (cost effective)!

Dear Kiran, It is a good idea of having a curvilinear false ceiling design for a living room plan like this. It will make your space look spacious as well as it will help create a character wall by accentuating the TV screen. The light colour palette will further make the space look harmonious and bigger. We at Offroad Designs, hope this idea will help you. Best Regards, Team Offroad

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!

I Understand. That's a common concern with my clients. But if you choose to have a 3-inch false ceiling, it will not kill the height. you need a minimum of 3 inches for the electrical conduits to pass. And as for the unhygienic environment, it is only created if you have a tray ceiling for cove light. If you install a plain ceiling after a thorough cleaning, there will be no hygiene problem. I hope this helps you all the best
