Got hold of an old 2 drawer filing cabinet (for this to work the cabinet has to have a base).
I took out the drawers, attached an inexpensive rubber doormat to front (was the side of the filing cabinet). I used a "no more nails" type of adhesive that is suitable for outdoor use. With this cabinet I didn't need to add drainage holes as there were already some hole sin the back of it.
The beginning stages.
I spray painted it all in a primer/paint all in one spray. This is an off white colour but anything could be used.
Filled with soil, planted some plants! Love it!
