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!

Hello Neetu, Trying to explain the suggestions earlier made with an image. See if the following changes makes the space more usable and open. Please see the numbers marked on the attached image. 1- Open up Dressing Area. No need of closing it. 2& 3 Pull out the Porch and increase the room size. 4- Change the direction of toilet, increase the size and include handwash within it. 5 Open Living area will comfortably seat 6-8 people. 6,7 - If your designer agrees this will allow you to increase the room sizes. by 20 odd ft. 8- Close the kitchen door . Change alignment of Kitchen slab and decrease wall/slab size on the other wall 9- Move Pooja Unit to the wall marked. Thanks Amit Cornerstone Designs. Bangalore.
