Shed maintenance/protection

[NotAGolf]

I need a garden shed, but I'm not sure what material to get.

I'd like to put it right in the corner of the garden to maximise our grass area. However, putting it right in the corner, or even leaving ~1ft around the edges, means I won't have access to coat 2 of the sides of the shed, which puts me off going for the wood option as I think it needs regular maintenance to stop it from rotting.

I'd be worried about metal rusting over time, plus they look pretty flimsy.

Might a plastic one like the Keter Factor be a better option? They're a bit pricier than a wooden Tigershed jobby, but not by a silly amount. I've got one of the Keter storage boxes and it's ok, but the lid has bowed slightly over time, and the base isn't strong, so I'd be worried about floor standing racks in there, and they're not sturdy enough to hang anything on the walls.

Any suggestions?

The metal sheds are galvanised - I fitted two at my mums place ~20 years ago and they are still as-new condition.

Wood can last a lifetime if it is on a proper base with guttering. It is the water splashes that rot it out from the bottom. My workshop is tanalised wood shiplap (albeit top shelf stuff) and looks brand new despite being fitted ~20 years ago. I phoned them up and asked what to do to protect it- they said nothing. I Barrentine'd it to be sure but it was going to fine without.

The plastic stuff seems OK but UV is what'll eat it eventually.

The key is getting a proper base (not something daft like pea gravel or soil) and stopping splash back (guttering/proper fall).
