Im jealous of the Tuff Shed or prebuilt being an option. Where I live we have incredibly high snow loads, so any structure ends up needing to be custom built to meet our requirements (even out buildings). I've found plenty of pre-fab units that claim to handle "high snow loads" that will not meet code where I am.
I'm still planning on building out an office/studio, but it will be a much larger investment despite being able to DIY much of it.
