Today was finally the day. The day I could draw three lines under the outside renovation of the rear of the house...
Preparation 1: gabions (I won't go into the hours it took just to sort these three plinths out. Let's just say it would be uneconomical to get someone else to do it.)
Preparation 2: treads: these are Ironbark (likely sourced from the property) that I remilled from the original rear verandah structure - each weighs the best part of 20 kilograms.
Ironbark is a really nice group of eucalyptus species. Our ones are probably narrow-leaved ironbark like these behind the house.
Step 1: each tread is held in place with 40mm batten screws and large square washers that clamp the tread to each gabion cage
I'm quite happy with this...
