Long story short I started to build a small bike shed just taller than the bikes from pallets last August. I managed to build the base and two walls with the easy to take off boards and stored some more. These are under a tarp so cold and I assume damp. These ones I was wondering if I was to stack in my diner away from the direct heat, would my home suffer?I would ideally like to start rebuilding in 2 weeks when got some time off. I have yet more boards to take off but these are proving harder and with weather in the south west not quick as all work is done outside.
