Thanks guys. That pretty much matches what I hoped for. I have put in an order just now for a Keter model that is a bit smaller ( it’s just 1.3 x 1.9 or thereabouts).

Site constraints made it necessary so I’ll just have to squeeze myself into a smaller space. But I won’t be sitting in the shed anyway. I’ll be indoors, warm and dry!
