Looks fantastic @Malcolm. Great job! Many thanks for sharing.
Please note that I've moved your post to our new Garage and shed board so that community members are more likely to find it.
What do you plan on using your shed for? Is it mainly for storage or will you get on the tools in there and have a workbench?
The shed holds my gardening tools and the lawn mower and my cement mixer and all my packets of seeds and the glyphosate and fertilisers. Made space in my shed for doing things in.
That photo was taken as soon at the shed was assembled, There was a bit of a wind blowing.
there are 8 L brackets now bolting the shed sides down the wood base, the posts are concreted into the ground.
