This is an okay layout given all the door / window openings in the room.

Would you consider building a closet that would hold the platform on which your mattress would be placed? The outer side of the platform could have drawers or doors to the storage units under the platform. This kind of enclosure would work better for a twin bed than for a double, but it would provide a place where the bed can be concealed during the day time. Then, if you could allow a path between the bed enclosure and sofa, you could have the sofa face the dining table, or you could place the dining table at a right angle to the end of the sofa.

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.
