About 15 years ago, I used to know someone that I played WH40K with occasionally. He had his hobby room in a large-ish shed at the bottom of his garden, inside of which there was a workbench along the whole short side of the room  — maybe 2 to 2.5 metres long and probably close to a metre deep. This was literally covered in tools, parts, half-built (or half-disassembled) models and toys, bits of interesting stuff, and plenty more. The only time the actual work surface was visible was when he was digging around for something. He built his 40K models on top of all the crap, or in spaces he sort of cleared to do that in.

I really wish I had a photograph of it, but this was before iPads were a thing, so the couple of times I was over at his house, I didn't have a camera with me
