If I had all the time and money I needed I would build my shop like a traditional industrial revolution brick factory (with an enormous bridge crane!) These are some gorgeous buildings we saw in San Francisco. I'd very happily transplant that bottom building directly onto my land if I could.

But alas, I am working with el budget-o pequeno (that's spanish), and as such I will almost certainly erect a prefabricated steel building, which might look something like this. It won't make it into Architectural Digest, but I actually like the way they look.
