Hi,
I’m currently exploring the idea of building my own outdoor seating with planter boxes being incorporated into the backrest.
I've knocked up a design on sketchup but am not sure how to approach the inside of the planter boxes.
Ideally I want to avoid filling the entire planter section with soil, what could I use as a base so the planter is only 300mm deep?
Hoping that any suggested material will also work to stop soil from filling the entire backrest and spilling out the rear as the seat is going to be against a fence so will have an open back aside from the planter section.
Thanks for any suggestions,
Mitch
