The places I'd actually put a fridge: 1) The main one in the kitchen for everyday use. 2) a spare in the basement near the TV room for snacks & drinks when people come over to watch a game or teens are hanging out. Also used as extra storage when buying things in bulk or when preparing Thanksgiving dinner. 3) possibly a spare in the garage for drinks when I'm working outside and don't want to track dirt/grass into the house from the garden. 4) a small one in the dorm room at boarding school or college.

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 don't think your kitchen will be dark. because there will be light from dining room. in case utility can get a glass door. Still if the fridge wants to be moved out, u have to go for a partition next to Master BR entry n place fridge facing dining room.

Hi, there. Your layout sure looks perfect, we would advise you not to make any changes in the plan. But, in the 3D render image we would suggest you to either push the fridge to a lil bit right or left, so you can get a continuous line of upper storage. It would make a good look for the kitchen. Thank you.
