So sorry.....I see the dimensions on your floor plan now....oops. It was middle of night here. You have a great place with lots of options. I will try to find a picture for you, but here is what I would try. TV on left wall. Put it on a console table 20" to 30" high, or wall mounted with a wall mounted console below. TV should not be too high or too low for viewing pleasure. The main walkway to the balcony will be on left side in front of TV. To see how the arrangement feels, Try your sofa on the right wall facing the TV. Then put one of the chairs in front of the sofa with its back to the glass and the other opposite of it with the back to your entry. If you feel this arrangement is too far from the TV, a sofa table can be used behind the sofa to move the whole seating arrangement forward. Then if this feels good, you can add a rug. The rug should be at least big enough that the front feet of the furniture can rest on it. You will then need tables on the sides of your sofa. You have the choice of a coffee table or what is called "cocktail ottoman" which you can put a tray for drinks and food on, but still put your feet up. That is always nice when watching TV. If you like this arrangement and go to buy new furniture pieces,get the chairs on each side of the sofa that swivel so the person can watch TV easily. You need to think a lot about what colors you will use in this houses if any rooms are done, take some cues there. It's a big decision that will influence every purchase. Find a 3 color combo that appeals to you. Again look on Houzz at the living room pictures. Post some here that you like.

I am an amateur lover of home decorating. I too have a very awkward long narrow living room that is 350cm by 620cm. Additionally it has diagonal traffic flow from the front entry to the rest of the flat. The owners have built a cabinet at one end for the TV, etc. I think I would make a cosy seating area at one end of your long living room. Place a grey or brown sofa at one end but not against the wall. I like the idea of a narrow console table behind the sofa with a table lamp, a plant or a large statue. This brings the end wall closer in. A peachy or raspberry carpet in front of the sofa will pick up the wall colour and anchor this seating area. (grey and some browns also coordinate with raspberry/peach). A couple of raspberry sofa cushions can help include the wall colour into your overall scheme. Single chairs opposite the sofa allows visual and actual flow down the narrow room and completes this seating area. At the other end of the long narrow living room I would place a reading chair, a floor lamp and a small round coffee table. If there is room you could have a tall bookshelf with you favourite books. What do you have on the long side walls? I have windows and doorways on both long sides. I decided to use pull up shades on the windows instead of curtains which I thought would make my narrow living room look more narrow. The wall colour is white but I think I will tone it down to a soft grey. I plan to paint the end walls a darker grey.

Some links you can look up for ideas on multipurpose furniture: http://bit.ly/1yJjARr http://bit.ly/2ouZevd You can also go in for low seating/floor bed and a square coffee table that doubles up as an activity corner. Keep the colours soft, and accessorise with small indoor plants for a cool, breezy look.

You're Welcome Mr. Patel :) Yes there are some plants that are better suited to indoor environment here's a guide for the same: but no plant can survive indoors indefinitely. you will need to to keep rotating them weekly or every 2 weeks. are you partial towards glass then sure it can be used. maybe paneled glass partition or a stained one like you mentioned earlier like these: The room does seem a little cluttered, which maybe because of the many different styles and no of things too. I think that can be helped by lightening the space a little and maybe bringing in a bit similarity specially the side tables and coffee tables . i have suggested the sofa upholstery color in the previous comment. shades of sage in velvet. if not then light beige in linen is also a good option. Something like in this picture https://www.houzz.in/photos/architectural-digest-india-march-april-2016-farm-house-in-delhi-phvw-vp~70030021 https://www.houzz.in/photos/vila-by-the-sea-phvw-vp~55949655 https://www.houzz.in/photos/aptes-bona-fide-expressions-phvw-vp~112062304 https://www.houzz.in/photos/sex-and-the-city-phvw-vp~94528292 https://www.houzz.in/photos/brentwood-transitional-home-phvw-vp~99412992 some bright colored cushions and an accent piece of sofa or some bright table cloth might also be good. as for curtains that will depend on the sofa upholstery you use. If you keep the same upholstery i think a nice pastel color would look better. something light. you should also choose light cushions and carpet for these sofas. and if you keep the same sofas i think you should atleast change some of the tables. I would also suggest bringing in a little more light to the room if possible. I hope this helped you. :) Best of Luck, Purva Saksena
