Is a tv being place in the room? If not, try creating a seating and conversation area floating in the center of the room....maybe with two small sofas facing each other and a coffee table or ottoman in the center. Or two chairs and a sofa, the two chairs are more versatile for layout options. Good luck!

Unable to attach pic! Hence describing the drawing room - On the extreme right corner of the longer wall is the entrance to my apartment. on the shorter wall there is a window and the opposite shorter wall has the TV point. The other longer wall has an opening to living room. Hi All, Need your advice on how I should place furniture in a rectangular drawing room(19`6" x 13`0"). Attaching a pic of the floor plan. In pic a sofa is placed on the left wall however we are planning for TV there. Please share your views Thanks

I may be wrong, but I think this was intended to be a living room and dining room. So I would move the whole seating area down to where the rug is in front of TV and get a table and chairs.

I'd do option 2 myself. Technically I see an option 3- putting the couch out in the open, diving the two spaces. Couches don't need to be on a wall- you'd just need a smaller couch to do that and still have space to pass through to the other room.
