Below Deck - A garden project

Yet another incomplete project I've been working on! This time, I'm garden creating a space for my daughters hot tub underneath the raised decking area. This space wouldn't have been a very usable space as it was, in the shade and uneven ground, so it made sense to create a sheltered space for the hot tub and much further down the road, we will enclose it for use as a catio for Mango (our indoor cat).
Like all of my projects, I am on a tight budget and reusing/repurposing lots of materials to keep the costs down. Left over a ballast for the retaining walls, sand and brick pavers from my courtyard renovation.
The astro turf was originally going to be used in the courtyard, but for one reason and another, that never came into fruition, so we are using it here, which I think will be ideal for an area that is compromised and mostly in the shade.

I haven't been following your work religiously but from what I have seen, you may not be a professional builder, me neither, but you're a clever man and I take my hat off to you for the unbelievable work you've done so far. You appear very knowledgeable and seem to take everything in your stride. You have my respect!
