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.

Hello Sd, You need to send the drawing along with the dimension and the present furniture measurement.

Hi Ajinkya,. you have a fairly straightforward and neat plan. I will suggest the TV position on the wall adjacent to the door in living area. Never have TV opposite a window since glare can disrupt viewing quality. Dining can be tucked at the corner where dining area is mentioned with a nice concole unit which can have crockery storage etc. and top of the console can have accessories and a painting flanked with bracket lights. avoid hydraulic table since it looks ugly and boxy on the wall. Get a chic and elegant rectangular table with a chandelier or hanging lights. Sofa can be 6' approx. Get a single 6' long sofa with a day bed adjacent to it so that you can move as you want. get a nice sleek center table with a rug in the center. TV unit can be designed and will become a feature of your home since it's getting an entire wall. some examples of our work and Pinterest options are below.
