Pallet planters are not that difficult to build. Place vertical beams of pallet on the brick wall for support then fix four by one pallet cases or pallet planter on them. Use lights to decorate them and also hang cages to make the look complete.
Pallet gardening, perfect for gardening within a small space. Always take advantage of empty vertical space--it will leave your balcony or patio looking clean, not cluttered. I frikn love stuff made of pallets!
