You have all the reasons to redo the house, its very lifeless and looks worn out. I feel creating a separation will terminate the spaciousness of the room. Adding colours will surely help, Since you have a tan color sofa,I suggest grey, white or light blue color on one of the walls. Add some art works of the color you chose for the wall. This room needs some fillers like , books, throws, candle stands tall and lean. YES DON FORGET 1. Mount the tv on the wall make some space on the floor and Fix a large size mirror ( Wooden Frame if you can afford).

I agree with eztia - you need to give a raison d'etre to your room and pale gold from the upholstery will tie in with the room and contrast against the candy pink wall. If you could find a discreet candy pink and pale gold curtain you would have hit the jackpot!

The architects have spoken. I have worked on a couple of building in India somewhat similar and know that this is well liked and fairly common. It does need to simplify but you can do this with color so that the parts introduce themselves not all at once, but with a sense importance relative to the massing. With deft coloring you can give balance and you can make the parts feel like they belong to a whole. There is no need to be simple in the Meisian sense. Lots going on can be quite nice. But with a detailed building as with a person, when you meet them you don't need to know everything about them, see the baby pictures, see the scars from their latest operations. No, you just want the person or building to make a good first impression. Then later as you get to spend some time with them and get to know them you can discover all their intricacies.

You can use natural stone like marble for floor but do not use granite for floor at all as it is very slippery when wet. As for tiles do not go for glazed vitrified tiles for the floor for the same reason. ( floor becomes slippery once wet and may cause mishap) Go for ceramic anti skid tiles that are specially meant for bathroom floor. For wall tiles you can use whatever you like and then decide over the matching anti skid floor tile/ marble. Double charged vitrified tiles are usually used for flooring in rest of the house.
