You have all the reasons to redo the house, its very lifeless and looks worn out. I feel creating a separation will terminate the spaciousness of the room. Adding colours will surely help, Since you have a tan color sofa,I suggest grey, white or light blue color on one of the walls. Add some art works of the color you chose for the wall. This room needs some fillers like , books, throws, candle stands tall and lean. YES DON FORGET 1. Mount the tv on the wall make some space on the floor and Fix a large size mirror ( Wooden Frame if you can afford).

I think a comfortable distance between the island and the counter is around 42". It seems that you have only 30" between your cook top and the counter. I might be a little too tight. The wall between the entrance and the kitchen could be 4' long instead of 6', you would then be able to move the island a foot which would give you more room between the cook top and the island. Could you switch the location of the toilet and vanity in your dad's bathroom so your enter facing a vanity instead of a toilet which is a lot nicer.

Thanks, for the reply. Yes, I am hoping to feature the mdf on the wall. I am not sure like which one to choose and how to make it look better. I want to make use of the entire wall with cabinets. But, I am open to other options also. There is also a pillar next to the wall on the left side. I also want to make use of the space between pillar and wall (like glass cabinets). Needs your inputs, if you can share some images, that will be great.

What are those red curved lines? The measurement is also not clear. What i understood with this is that , You should have two different rooms - one is formal drawing room with only sitting area and for that you need not provide a partition as it should look grand from your entryway and second one should be the living room. There you must give a partition between both the rooms so that the person sitting in the drawing room cannot peek in the living room and it'll be kind of privacy as other area will also be not directly visible . By giving a partition you are messing up the passage way more.
