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...

U-shaped layout wold be the most efficient use of space.

can anyone tell me what kind of flooring is used here ? thanks in advance

Hello there, The flooring shown is a concrete flooring with oxide paint treatment of Grey. It is called Indian Patent Stone or IPS . Try searching for Athangudi flooring and you will be in for sheer delight. Regards, Aurum Ideas and Spaces Bhubaneswar
