Example below: The wires need to run up behind the wall to the ceiling (see image below). A return was created between two existing walls (you will need to create two columns) - through which you can run the wires if necessary. The screen is hidden in the beam above the painting. In the foreground of the photo is another "beam" which actually contains the projector. It has an access panel again covered in the mesh and there is a flap that can be removed or opened/closed when the projector is in use. US is way more advanced, so I believe other Houzzers can step in...

Hi Cynthia, thanks for your comment. I still haven't decided about lighting. First, I'm trying to get as much natural light as possible. If there are still some dark corners left, then I'm planing to use light on those areas.

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!

Nadia, You need to provide some more snaps showing the entire room, including the location of the beam, its height & clear height of the slab etc. One idea could be to extend the width of the beam by just about 25 mm with gypsum board on either sides, at the bottom level, with a right angular vertical of 25 mm as well & provide LED lighting strip for indirect lighting...
