This is an extremely simple project doable by pretty much anyone with some simple tools and a spare afternoon.
I needed a way to tidy up my planters on the patio, keeping them sheltered from the strong wind we get here as much as possible and keeping them from blocking out each others sunlight.
you will need-
measuring tape, pencil etc
Step 1: Preparation
Get some wood planks, I used some treated wood from the local DIY store but old pallets would work well for this. I had one 150mmx20mm plank, and some 50mmx20mm battens.
The design is based on a 3-4-5 right angle triangle which simplifies the math for the design. The planters are 200mm tall, and about the same depth at the top, the bottoms are about 150mm deep. I needed room for 4 so the ladder would need to be at least 800mm high, so it would be 600mm deep, and the longest side of the planks needs to be at least 1000mm. I cut them slightly longer to give a bit of room at the top, the plank is 2100mm long which is perfect.
To calculate the angle to cut use the 3-4-5 triangle to mark the shape on the plank at the centre and saw at the plank to give 2 equal lengths.
