I recently decorated a mid century style living room that had an open floor plan. One wall in the room was completely paneled, including a built in cabinet. Removing the wall paneling was the best thing I did to bring the entire space together. Once the drywall was up and painted, I moved the dining table from a small area off to the side to the more open space behind the sofa. I defined the area as a dining room by centering a fixture above the table and anchoring the table and chairs with an area rug. Having the walls all the same material and color made the room feel more cohesive and helped the stone fireplace stand out more. The paneled cabinet will be removed at a future date, so painting it the same color as the wall helped to deflect - rather than emphasize – the panels until they are finally gone for good.
