I spotted this planter on Atlantic Avenue here in Brooklyn. I really like the simple, straightforward design. It has a hint of the orient to my eye. It could easily be a sub-irrigated planter (SIP) if it was lined with sheet plastic to make it watertight.
Power tools would be nice but are not essential to make this planter. All you need is a measuring tape, handsaw and hammer. A carpenter’s square would be helpful.
Wood from recycled wood pallets would work with this design. The planters below at PS39 in Brooklyn were made from recycled wood pallets. They conceal sub-irrigated planters (SIPs) made from tote boxes.
They could also have been lined with plastic to make them SIPs instead of using tote box SIP inserts. The totes provide more flexibility but cost more. Any size planter can be a SIP using sheet plastic liners. Both methods work equally well. It’s your choice.
