Thanks, Mad Goatwoman, I had a feeling that we need to add ventilation holes.
Any thoughts on where the ventilation gaps should be specifically?
Do we need to leave permanently open holes at the top, like actually remove a section of the top of the shed walls? Should we put a mesh over the holes?
What I'm trying to ask is, does it need to have permanently open holes, or would we want to close them sometimes?
Trying to work out how tricky it's going to be and what we need to do!
Thanks
