thanks for you idea \ but i will clarify a few more points 1.the area for bedroom and sitting room is on 1st floor 2. it is actualyy like a big hall unpartitioned at the moment 3. the sitting /living room is not like a common room ,it is only for this bedroom 4. i dont want to change postion of the bed on any other wall,i want it to be the partioning ,in some unique way. 5. i dont want the room to be totally divided into two halves by the partition --whatever is designed . 6.the siiting room is proposed to have a book shelf on one wall ,provision for tv panel and one single seater cane swing (hanging type). I HOPE THIS CLARIFIES THE PICTURE SOME MORE can you think for me now and help with some unique idea.

In all these examples, the breakfast counter separates the kitchen from the dining/living area, and is higher than the rest of the kitchen counter, to give some privacy to the chef and hide the mess of food preparation from guests

I'm not an architect, but perhaps that drawing room corner could be done as a diagonal wall with French doors.

It will be better if you don't think of separating it .
