am assuming this is a concrete structure, when shifting service toilet to utility area, and if there are apartments above, then running extra lengths of supply/drainage lines & introducing a structural sink slab (if this is concrete) under the new location can be charged extra.. it will be easier to divide the 3rd toilet. all services will be already available. only, do check on supply & drain pipes capacity as load is increased on the same pipes which were serving one toilet earlier..

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.

Usually when you get side panels you automatically have space on the sides. If you have a full depth cabinet on the top, you automatically have space at the top and in most cases you will have leave at least 1 inch of extra room for the back of the refrigerator, so there is always air circulation since everything is enclosed. In the 70's they use to make a small recessed space behind like Fred said, today you don't have to do that, most Ref have flat backs, recessed wiring, not to mention the supply for ice-maker also comes in a flush mounting kits for the wall... so pretty much everything is recessed and only space you need is for air circulation and 1" is more then enough. In addition, if you make recessed area now and you push ref to far you will never get your doors open so doing all that is a waste of time, in addition most manufacturers starting to make 30" side panels.

I want to make this space - the top drawer, directly underneath the countertop - into a charging drawer. I want to throw all the phones and iPads in there, charge them, and not see them. The countertop directly above the drawer is granite. There is an outlet a few inches above the back of my present drawer. The entire cabinet (stack of three drawers) is sandwiched between two wood "walls." Is there some way to get an additional outlet on the wall, behind where my charging drawer would be, underneath the countertop? Or in some other place, where I can thread it into the back of my charging drawer? Thank you!! - june
