In my opinion, a large part of permaculture is having a stash of resources to draw on for building projects. The resources are usually acquired for free, or at very low cost. They can consist of wood, steel, glass, brick, concrete or organic matter. As long as you can store your resources out of the weather, you’re entitled to as many as you can collect.
In the process of shifting, I discovered how many resources I had stored under the house and under roofing iron in the yard. First off, there was a lot of lumber with nails removed, as well as roofing iron.
I moved my best pieces of driftwood for making cool stuff.
In the former horse stables, I am building a lumber rack.
More wood and a giant window for reuse as a glasshouse. 
We ended up moving 2 cubic metres of compost.
This is Verti sorting her lumber.
Well done, girl.

Thanks for giving us the perfect word for what onlookers insist on referring to as “junk”. It is, indeed, stockpiled resources. And you just know that, were you to (heaven forbid) jettison any of it, the chook house door would break or the feed shed would spring a leak and you’d have nothing to hastily nail onto it at 2am in the pouring rain!
Native Americans believed that any medicinal cure could be found within 10 feet at any time. I like to think the same about my shed in terms of nuts, bots, screws, washers, brackets and nails.
