You can opt for the frame work of solid wood or waterproof plywood , polish it , can install lights at cross section , I don't know about the size and shape of your room . This way you can have ceiling fan also at the location you want . Easy and simple solution. will look elegant as well

Thank you. Point noted. I will remember that while we choose our decor so that i mix and match a little to break the monotony of the theme. I forgot to mention- there is one other reason why we settled for the no-false ceiling decision. I love the height of the ceiling and the ample natural light in the room. We did not want to cut off few inches by adding a false ceiling. We might add a portion of wooden ceiling perhaps if we feel that might be good, in future. But as of now is there no other option to make the room look complete, without the false ceiling I mean? Perhaps solid or textured paints-light reflecting colors on the ceiling or something like that... and getting back to the topic of false ceiling, are there options that can be added without reducing the height of the room? Because the two options that the designers gave me are wooden panels or POP wherein close to 1/2 feet is lost totally.

the more gap you have the more light will diffuse. the beauty of cove lights comes from that gradient. if you have a small space then that look won't come. additionally, refering to your previous post, it will also be a place for pests. If you want this design, I would suggest you go with an LED and cover the gap with an acrylic cut out. that will give a nice effect. or create two levels, let the flat part stay where it is and make the circular one a recess

Greetings from Aura you have two options here go for indirect wall lights or wall lamps direct pendent lighting from slab point would also look good many ceiling lights options available suitable for no False Ceiling wall lights are always better it creates ambience.
