If your foyer lacks architectural interest, secure an oversized decorative wall shelf or bracket on the wall directly facing you as you walk through the door. I like to place them on the wall at least five feet high or higher depending on ceiling height. This is a great place to display an elegant antique vase or urn. In a less formal setting you may want to display a simple pot of trailing ivy to add softness. This is also a great idea because it keeps your floor space free of clutter.
In a small foyer maximize the light and make a tight area feel less cramped with a floor to ceiling mirror. Your foyer may be a tiny space with only a coat closet and no place to hang a mirror. So why not mirror the closet door! This will make your space appear larger. Depending on how your closet door is positioned, it may double a gorgeous view of the outdoors.
