the back wall panels look like ikea besta doors. the hanging cabinet could also be besta boxes, but with customized doors. the console in front of it, you could get a similar look by using a malm console table and cutting it to height. from there you'd want to use a couple of besta cabinets to create the closed off storage. the low bench could be made with plywood and then stained or painted to match the finish of the malm/besta combo you choose. besta cabinets :: http://www.ikea.com/us/en/catalog/categories/departments/living_room/11794/ malm console table :: http://www.ikea.com/us/en/catalog/products/80196480/

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.

It has a descent lighting. I like bold colors. and this is a living room still in construction. The room has rectangular shape, this is half of the room. There is window on the opposite side of the TV(my back side while taking the above picture). The window size is 6 x 4 feet.

Your choices don't flow well to me. The flooring in your photo is pretty (very dark...are you okay with it showing every footprint, smudge, and dust bunny? If so, that's fine). From all of your options there I would do white cabinets with the Himalaya White granite. But you said ignore the granite. :) I would go for the gray cabinets with white quartz everywhere in that case, but personally I'd worry about gray cabinets being very dated in a few years. Is there another quartz option that you could pair with the white cabinets that is light in color and maybe has some movement, like LG Bianco Drift?
