If you want a new outlook, move some furniture. The first step is to create a new focal point, says interior designer Ron Renner, founder of Certified Interior Decorators International. Consider an armoire or a fireplace, and arrange chairs and side tables around it. Renner isn't a fan of rakish angles. "Putting couches on the diagonal wastes space," he says. When placing furniture, Natasha Younts, CEO of the Designer Society of America, follows the "three-feet rule": "If you want to put a drink down on a coffee table, you shouldn't have to reach more than three feet from the couch," she says. "And a pass-through area should be at least three feet wide." After you change a layout, observe how people use it. "We all flow toward the space that looks easiest and most appealing," Younts says. "If guests aren't entering the living room, maybe the couch is a barrier. If they're not using the path you created through the room, expand it to help direct them."
