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).

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

Thank you IDUS Furniture store for looking into my query.I have a doubt ,if I paint my front wall where those 2 chairs are kept,is it mandate to paint a L shape wall behind sofa? if yes, should I be going with the same color as the front wall? Just FYI- I have a brown and beige ceiling and was planning to paint my bedroom doors with darker shades

Please let me know if I have understood you correctly. From what I have understood you are looking to place the bed on the window wall. If yes, then it won't be a good sight every morning that you wake up to see your bathroom door. If the dresser isn't a fixed niche you could swing your bed between the two dresser slots. That way when you walk into the room, it will make an impressive entry. Think about it! Regards.
