Great work @Oldfart! Many thanks for sharing. I'm sure this will inspire other members.
jus5 wondering how and where can I get the plans, measurements etc for the 3 tier plant stand?
Welcome to Workshop, our online community for D.I.Y. and gardening discussion.
Workshop member @Oldfart obviously hasn't shared plans in the post above but did seem to indicate it was a project conducted at a Bunnings D.I.Y. in-store workshop. Let me tag the ever-helpful @MitchellMc who might be able to track down details for you. Otherwise, the wonderful @Poppop might also be able to assist as he often makes similar planters out of fence palings.
Finally, you might also be interested in this similar project - D.I.Y. tiered timber planter. There's a video, step-by-step instructions and a full list of tools and materials.
