Looking great Marcus,
I was going to ask you how you plan on waterproofing the base but from your first photo it comes with a base
In South Oz I’ve used agapanthus around my deck and once it grows actually preserves the edges of the deck from our harsh sun. Also acts as a good fire retardant. Could possibly be classed as a weed over there though?
Have enjoyed watching your build from the start!
Cheers
