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).

Colour...objects of interest...lighting...all add "energy' or we refer to as "movement" in a space. Interesting pieces of furniture with different textures and different "eye-levels". For instance, you can purchase 3 or 4 different forms of seating options...you are in India so you should be able to find FABULOUS furnishings for great prices. You could purchase a low-slung sofa, an extra large "floor pillow" (it would act as a chair or foot stool), a leather-covered round ottoman and an interesting crate/box with a slab of glass or intricate wood over top...this is your seating arrangement for the living room and will work as a great "hang-out" space that you can enjoy by yourself or with a tonne of people hanging around! With all that visual "movement" from one object to another to another, you will create interest! And "interest" is energy! But your best bet for energy...people!

You could also bring in some texture with bamboo sticks or decorative branches and help balance a bit the height of your room with small scale furniture. Spray paint them if you find the perfect size and shape but they aren't the color that you need. Ikea carries white decorative stalks for a very good price. the ones in the 1st picture hold well with small kids around and you don't need a vase for them. there are washi paper or crinkly paper floor lamps with a soft beautifully diffused glow For a budget friendly version check ikea or target http://www.ikea.com/us/en/catalog/products/80028552/
