The furniture layout on the floor plan shown looks fine, but seems to be scaled down a bit especially with the sofa and loveseat.

Hey Amit, Living areas need an clean flow of foot traffic. keeping it near the balcony would be ideal. that be default leaves the centre of all the door opening to be your dining area. To make the best of the space you will need modular and multipurpose furniture. This is something a trained designer will be able to help you with better. While DIY is an ambitious goal. This is a challenge. We would advice finding a designer that you felt comfortable with. Hope this helps! Best CUBSpaces Team +91-9923893771

Here is a wall that does double duty. T.v. wall and desk wall, also give you extra seating to pull out when you have company.

I wouls get rid of 1/2 the pillows on the sofa too matchy add an area rug that is bright with some other colors to use for accents you have IMO too much brown so I would do blue drapes in the DR take the cloth off the table and add a blue and orange glass bowl for a centerpiece filled with green apples get some pillows in green and orange and a big piece of art work for the wall above the sofa and maybe a mirror on the DR wall and a fabulous light fixture for the DR an arc lamp behind the sofa in the corner so it comes out far enough into the room to light a coffee table.
