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...

Very pricey in many areas, and not necessarily an advantage. Hard to heat, cool, light and handle the extra-tall windows. 9-ft. is the added height norm, although one can always add additional volume with a peaked ceiling or similar.

I would tend to agree with the architect because they have the vision of the entire space. This is a discussion you should be having with him/her so they can explain why 10 feet is better, or they can adjust it to your preference.

Hello can someone tell me the ceiling height for commercial buildings in India? Is it ok if we take 14 feet
