Leaving your fridge next to the wall (as shown above) is always the wrong way to go. Not only does this make the entire design look poorly planned, but it’s also very impractical – and here’s why:
The door must open up more than 90 degrees in order to remove the drawers and to clean your fridge properly. The more the door is opened, the easier it is to put in and take out food. Just think about how difficult it’ll be to store a leftover cake or a Thanksgiving turkey if the door doesn’t open wide enough. Holding the door with one hand, so it doesn’t close, while trying to get a few items out, is a big nuisance. . . . Also, opening and banging the door may damage both your refrigerator and your wall.
While some designers will suggest adding a filler of at least 3″ to provide additional space (think about the thickness, weight and even the handle of the door, not to mention the wasted space), the best design is to re-position your fridge. Design a standard wall and base cabinet of at least 12” to the side for additional counter space or add a tall cabinet – that also helps to gives a built in look for the fridge, like below:
