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).

You have a nice geometric, somewhat masculine look going here. I would play that up. I don't think you need to change the wall or carpet color as they seem to be a nice neutral background. Are they cream? is the purple more plum? and is the blue more of a steel blue/gray? The furniture is chocolate brown? I love the striped pillow on the chair. I would layer a wool steel blue/gray area rug and then play up the blue/plum in the pillows. A wool plaid or blue gray herringbone in a couple of throw pillows (replace a few of the solid color pillows) could help to pull it all together. Kind of like the colors in the picture of this bag. Adding brown leather cording would be a great compliment on the pillows. (Not sure the area rug in front of the TV is adding anything)

Cost is a factor also between papering and paint. 20 years ago, I painted and wallpapered everything myself. 10 years ago when I moved and bought a condo, I hired the papering and I did the painting. Last year when I downsized, my handyman and I just did the painting. No paper. I have found that at my age papering is too much for me. When I get down I can't get up and when I am up it feels too good to get down :>)

Hi Neharika, if that wall is not exposed to water from outside, you could put a wallpaper there, there are beautiful wall boards also available in the market. Textured paint is another option. We could have the same wall paper/board/textured paint on the piller as well. You might have to move idol of Ganesha and picture near the pillar to some other place. Large paintings look better in living area as half of the wall is covered by sofas. In dining area, even if you cover upper half by painting, lower half remains exposed. So full wall needs to be decorated. More queries are welcome :-)
