What's the best layout for a formal living room?

The kids have left home so I want to create a more formal living room. What's the best way to lay out it out?

If you want a formal room, whatever your style, the one rule is symmetry! Arrange furniture symmetrically and you'll give your room the grown-up look you're after. If you have plenty of space, move your sofa so it's facing two identical armchairs or an identical sofa. You can also use tricks like adding a pair of side tables with matching lamps, or arranging a set of four prints in matching frames on the wall. If you don't have the space for all of these different elements, choose smaller pieces such as carver chairs instead of upholstered versions. Then just arrange them around a focal point - whether it's a fireplace, window or a coffee table.
