With your original pictures - I agree with larger rug. But I don't agree with comments suggesting the rooms are monochromatic. They are lively indeed. I think you are just missing some accessories! Art work on the empty walls - even just a single large dramatic piece is in order. In the bedroom on the white wall, in the living space behind the sofa, in the greenish bedroom behind the two beds. Those are instant areas where you can improve. But I think your spaces are lovely and well put together. Also I agree with the comment about table lamps - some of those would really add something, and your coffee table looks so empty - maybe just one gorgeous bowl, or stack some books. These rooms are 90% done in my opinions, just need a few finishing touches. Some of my rooms come out like this because the clients are not willing to pay for those last few finish items or feel they can do that part themselves...

I'd have a white entertainment/study unit and a grey/taupe deep buttoned bed back (headboard) I really like the swing sofa! Could you change the chain on the swing chair to silver metal rather than black?I'm not keen on the other chairs though, I'd like to see a taupe/grey deep buttoned ottoman for the end of the bed to match the bed back. White bedding with a taupe/grey satin/silk bedspread across the end, 2 matching taupe cushions & 1 purple cushion with an emblem or monogram. On the swing sofa I'd have 2 more taupe/grey satin cushions. A new glass or silver & glass coffee table would finish it off.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

Hi Tanmayi, Going for white walls is always safe, this will helps in giving a light feel to the room plus gives a lot of scope to bring in the patters and colours to the room in other forms (like curtains, cushions, wall art/frames, etc) PAINT SHADE(2 Options) Would also like to advice you to have a subtle wallpaper either in the niche portion of the TV wall or for the entire headboard wall. (Assuming the other walls may have windows or doors) SOME WALLPAPER REFERENCE IMAGES: Later you can gradually bring in other elements as per your taste and time and pull up the room together. Hope this helps! Best Regards, CUBS Team!
