Have a box of a room that's just made up of four walls with little architectural detail? It can be tough to come up with a layout given that much freedom. But it can help to begin to create a framework for yourself:
Take a cue from this Tribeca living room by Lisa Sternfeld Interior Design. A pair of stand-alone shelves flanking the sofa create niche for the main seating area in the room. Using movable shelves like this to anchor a space is smart, as their location can be adjusted and easily "customized" to different spaces as you relocate over the years.
