Hello, Avishek Naha. Houzz has over one million photos in the PHOTOS section. Please go to that link and click "dining room." You may save the ones you like in your very own Ideabook. You might wish to start a second Ideabook with photos of drawing rooms you like. Make notes in the comments box under each photo about what you do and do not like about the room. When you get about twenty photos in each Ideabook, you should be able to see a trend toward elements you desire in each space. Then go to the Professionals section of house. Look at some of their work. Find a person who has designed rooms similar to what you like. Contact the professional, hire him or her, and pay for architectural plans, building plans, and design/decorating work. You may also enjoy looking at the PRODUCTS section. You can make an Ideabook of items you would like to put in your home. Contact the manufacturer directly to purchase items.

You will need space to walk and for your feet if you turn the chairs around - if you put a divider in you will block the view from the dining table out to the balcony - and thus make the kitchen and dining room both have no view ! So if you keep it open, the natural light can get through !

In that space you will only really have room for some seating and a DR table and chairs I would be looking fo a long low shallow unit for the media pieces and hang the T.V. on the wall 10.5 ' is very narrow. The room in these pics is almost exactly the same size as yours , if you see where the empty fireplace is that is where I would put your T.V. and then wap the bench for the sofa .

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.
