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).

@Genevieve : that kitchen was too small they had an island inside ,the client insisted for the kitchen to be interesting that is why I came up with an yellow The walls were already there it was a very small opening with a door ..Then it was made open type for better space

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.

Thanks Nitin and Ideal Lifestyle. Sorry for the late reply, I don't know why my net is not working properly from the last few days. Ny way, I actually see the foating kitchen cabinet in google image. May be that it not good for our Indian kitchen. I love the drawyer system that offered in modular kitchen cabinet. But at the same time I have no patience to dry the the kitchenware (cookware/dish etc.) after washing. Now we put it on the steel dish rack (commonly visible in Indian kitchen) hanged in our wall after every wash, which no need to first dry and then store. But I want to conceal the dishes, pressure cookers, kadhais in drawyers. In my dream kitchen big kitchenware should be concealed, hanging cookware like saucepan, tawa, frying pan would hang on s hooks in railing and open shelve for the dry goods in glass/tin/ceramic jar.
