it looks awesome. i know its way to late but did you not consider some kind of damp proof course between your bearers and your finished floor? just worried that nice floor is going to warp over time
Putting in a damp proof course isnt suggested on any of the cabin sites I looked at so I didn't consider it.
It's not something I'm very knowledgeable about if I'm honest but I would thought that having the pressure treated bearers and the floor being treated both sides and the base being open on the left and right for ventilation that damp shouldn't be an issue?
I looked into it for my shed (built the floor today), but opted to put the bearers on bricks instead. No chance of getting wet and more air flow.
I'm sure yours is fine though. I'm just anal.
Most sheds/cabins I have seen have the bearers directly on the ground.
Gym equipment all built and in place. It was hard work building the power rack and lat attachment in the cabin, I almost had to build it backwards because of the height restriction.
