Even if your only outside space is the wall by your front door, a tiny terrace or a balcony, you can make it look much larger with the clever use of outdoor mirrors. Just check that they are suitable for outdoors before purchasing. If not they may crack in extremes of temperature. But how fun is this garden gate illusion?
Mirrors that look like windows or doors will add interest to a bare wall and reflect any plant life on to that space so that you will feel surrounded by foliage; and, it will appear that your little space leads onto somewhere else. They will also bring more light into a dark garden.
