This is not as sturdy as I would have liked but does the job. However, if you have red squirrels, they can scratch the wood (which they did at my house) and easily scratched off a bit of the top of the door. So not too indestructible. Could be made more durable.
We installed the shed about 3 months ago. My partner somehow put it together all wrong, and then had to redo it, so probably it would seem more sturdy if it'd been done correctly (he's a sweetheart, if not that handy). The walls could stand to be thicker. I hung hooks on the interior for tools and the fasteners jut out the back wall. However, it is perfectly functional and serving the purpose we got it for. It just remains to be seen how durable it will be. The other thing is it is extremely fragrant -- you definitely wouldn't want to be in there for any length of time on a hot day or with the doors closed. It's powerful.
