Gareth,
I found this very interesting reading indeed, as I have recently been thinking a fair bit about how to set up my new workshop after we move, including a dedicated painting area. As I've already mentioned, I think, we shall rent, so I want to avoid as far as possible making any holes or similar in walls or ceilings that cannot simply be filled in and repainted when we move out again in ten years or so.
Given that the basement where the workshop will be is all raw concrete or cinder blocks, that I am thus loath to make holes in, I am inclined to get a couple of Ivar shelving sections from IKEA (**LINK**), join them together across a suitable width of floor with wood lattices to create a sort of openish cage, and then cover the whole thing in heavy-duty plastic dust sheets or similar. For a door, a shower curtain ought to do, and then I was thinking I might put up a number of LED strips from the same source (**LINK**), both on the shelving sections and overhead. Up to ten of those can be connected up, and at 340 lumen each, a sufficient number should provide a both strong and even enough source of light for painting. And because they're LED, they should neither generate much heat nor make too large an inroad into the electricity budget …
Given the amount of very intrusive paint dust from airbrush or spray can painting, I am also thinking about getting one of these: **LINK**. While much to small for car body painting or similar full scale spray paint fumes and dust production, I think it should be perfectly adequate for airbrush work, which is after all my main way of painting.
Well, time will tell, but in the meantime, thank you very much for a most inspiring post! 
Mattias
