Hi, You don't say whether construction is completed and you've moved in yet or if you're going from this plan only. If so it's a good idea to live in a space for a while before knowing if your changes are really necessary. And you can change around your dining/drawing areas easily until you feel right about it. I'm not so sure if it would be a good idea to chop up the space like that, and the two furniture arrangements serve amply to define the spaces. If you are finding a real privacy inconvenience then here is a nicer solution i think. A semi transparent double sliding door like this across the study area opening would give enough privacy while at the same time allowing light to show through and not totally closing off the space :

hi, the idea of having a partition where proposed is definitely a big NO. As rightly pointed out by Interiorzz it falls at the entrance foyer which kills the look as soon as you enter. i would suggest swapping the drawing and the dining. if you could accessorize your balcony well and turn it into a rock garden - it would be a welcome view from your dining table - you could add a pretty hanging light above the table. the dining family lounge is 11'x18'6" as per your plan. I think thats a large space to play around with and it would give you a separate seating space which you could divide into formal and casual by using a chaise in the middle. the TV could find place on the bedroom one wall or you could turn the set up around and extend the 10'x7'10" room wall till where you have shown a partition between the dining and the drawing and put it on this wall. you could also make an entry to this room on this extended wall right next to the kitchen entry so you have uninterrupted walls in the foyer. The "L" shaped wall that results in the foyer can be treated with wallpaper or stone so its adds a feature to the foyer. hope this helps!

This is my drawing cum dining room drawing please suggest me how to design it. Its dimension is 23/15

@Nitin : One more thing is where to keep washing machine. if basin counter occupies the 4ft wall , then I will be forced to keep the washing machine on the 5ft wall side.
