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).

Stay with light beige for your main pieces like the sofa and chairs. Add in other colors and patterns with pillows and throws. Keep the drapes simple and hang them high as possible (with a traditional height ceiling not a vaulted). It would help to have pictures and to know what style of furniture you prefer--modern, traditional or a mix.

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

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
