One possibility would be to swap the living room and the dining room. Since the current living room is larger than the current dining room you could still keep some comfortable seating (couch and upholstered chairs?) against the front wall for a keeping room/dining concept. Then your new dining areas (kitchen and dining room) and living areas (living and drawing room) would have good flow between them, which would work well both for family and entertaining. You could also add some builtin bookshelves in the drawing room or new living room to create a library area to add another fun element to the living areas. These bookshelves could be against the long walls in the drawing room, around the window with a window seat in the living room (former dining room), or built to create some separation in the open area between the drawing room and living room/stair area. Your plan seems to show some sort of builtin there, but I'm not sure what it is.

Unfortunately all your options require custom work: It looks like you need an 18" corner cabinet. You will have to modify the last wall cabinet on the left. As I am eyeballing it, you should be able to cut the last cabinet in the middle and then shorten the left section to fit the space of the wall next to the door trim. It's an option that makes the area looks symmetric. Or you can install shelves over the sink. I would not recommend it because it will take the looks away. And the last option will be to remove the last cabinet, shorten it so it fits over the sink and install a single cabinet where the double one was. This will leave a triangle space behind the corner where the two cabinets will meet. You can block the space under it. Hope this helps!

coming to the dining area..yes id say you remove the seating entirely and concentrate on a foyer area since you already have space for a drawing room on the floor.. id suggest erecting a glass and marble wall in line with the wall that runs between the pooja room and the bedroom..say a bit of marble-glass-marble-glass-marble.in this case you have a small foyer area demarcated by this wall feature.you can deck it up by placing a nice console table in front of the central marble wall with a nice mirror to reflect the space and make it look larger or a sculpture with beautiful bracket lights on either side to accentuate the same.and on the backside of this wall you could have a crockery unit with a huge painting or a cluster of family snaps above it. if you could brief me a little on the look you're adapting for your house i could suggest some more treatments for the walls.if you want to avoid using too much marble you could also opt for a marble wood and glass look where you could take out some concealed storage for shoes etc. regarding the drawing room - what about a huge 4 seater in the center instead of 2 - two seaters with a table in the middle as in the plan..if you remove the central coffee table maybe you could replace the single seater with a chaise for 2 and also replace the 2 center tables with a nice long table in the center with an area rug running below it..if you could help me with the room dimensions maybe we could add 2 pouffes in front of the 4 seater so it creates more seating and doesnt obstruct the view if you plan to put a TV on the wall. what look do you have in mind for your terrace garden ? something zen or a little rustic toeing on the lines of the contemporary ? sorry for the late reply as i was travelling.. hope this helps! :)

@Rock Doc: Are you addressing this to me? I haven't actually bought these tiles yet - when I do, I will definitely be going for the handmade ones. They're a work of art and irreplaceable in my opinion. However, there are also screen-printed tiles available in the market in more or less the same patterns; the workmanship is of course different, but you get them cheaper, and they're also more easily available. You could give that a shot. I'd recommend Aakaar Flooring Solutions - they're here on Houzz and are able to provide both the above-mentioned types.
