Thankyou so much for your ideas. I was also thinking of sticking a graphic film on these...can you please guide if it would be correct to do it.and if yes, what would be good. Thankyou once again for the prompt reply.

like so (sorry took liberty with your pic using paintbrush app). in second tv be installed on an island of a solid wall, remaining wall be of glass: use frosted tempered glass for doors n all.. this way you get another expanse of wall to do loads with n utilize full potential (area) of room.. also providing a wall surface on the back of the tv 'island' wall to the sitting area for say a painting, maybe? plus tehre won't be glare on the tv screen either if it's on teh wall-glass partition.. only issue being the slightly longer approach (i-e through dressing room) to bathroom area, which ain't so bad either.. in ur original plan i don't like how a door is sprouting out in the middle of a great expanse of wall... what a waste..

What are those red curved lines? The measurement is also not clear. What i understood with this is that , You should have two different rooms - one is formal drawing room with only sitting area and for that you need not provide a partition as it should look grand from your entryway and second one should be the living room. There you must give a partition between both the rooms so that the person sitting in the drawing room cannot peek in the living room and it'll be kind of privacy as other area will also be not directly visible . By giving a partition you are messing up the passage way more.

There are lots of self adhesive wall papers with lot of good design n sizes u can stick them over it no need of professional help but try to get waterproof or the one u can wipe it with wet cloth some of the available on Amazon n cheap way of remodeling ur furniture look... I hope this can solve ur problem
