Let your wooden beam be as it is. put your Led lights in the other direction ( two on each side in one rectangle , so the total will be 16 units of say 10 watt each Led.), as to balance the horizontal and vertical shape. Don't put anything on the wooden beam to retain its the beauty.

Hello Amruti, Posting images of a project done by me which has a breakfast counter & opens onto the dining, its to give you an idea on a concept of open kitchen. The design style can be changed to ur aesthetic sense.. Thank you.

Hi , I understood what you meant. Seeing the layout you can utilize the wall adjacent to toilet as a position of tv unit and keep your sofa in front at least 7 ft away. your dinning table position should be at the terrace side and considering the size of the room it should be 4 seater. you can utilize the wall opposite to your kitchen for decoration ..book shelf ..etc. If you want a suitable 3d design to be done you can contact me on my mentioned contact details. Regards

Better to opt for L-shape sofa for the above position.. Bedroom appears to have occupied more space than living room. If it's already finished,. you may have to opt for compact furniture,.. Or reduce the size of bedroom first; then proper living/dining arrangements can be done.
