@Yorky88 - in the grand scheme of things it probably took a day to build the planter box with the sleepers and then the cladding took another day to set up.

Thanks again for sharing.
They are treated pine sleepers @urbanartisan. You can see pictures of before they were clad in this discussion - https://www.workshop.com.au/t5/Garden/Backyard-Makeover/m-p/15109
This is a brilliant stylish project that could be taken to the next level and turn into a wicking bed
