The foyer is the room that greets you as soon as you step through the front door. This is the first space and sometimes the only space guests see of your home, yet often foyers or entryways are neglected. This strikes me as odd. Somehow, I always think of the foyer as one of the most important rooms in the home. The foyer is usually where first impressions are made.
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.
