Great if you only want a shed.
One of my co workers in Denver built a Tuff Shed for his home studio and I thought that would be great for me. I am in Raleigh so I worked with the TS team here to design a semi-custom solution for me. We discussed how it would be finished and insulated. TS did the permitting and install but several things became an issue soon after. A window was installed where no window should have been and, when TS was notified I pretty much got a shrug. I needed to hire someone to remove the window and repair the siding. Also apparently TS is not a GC so I had to become the GC instead of them to get electrical permits done. Again, a shrug from TS. There are no eve vents in the roof so if you want to insulate the building it is up to you to have those cut in, installed and the rafters modified. The rafters were not even so you need to fur them out for drywall. The transom windows are glued in and not caulked so you need to caulk these if you want a weather proof seal (they are not insulated or thermally broken by the way). In the end it cost me over $1300, or more than 10% the cost of the shed, to modify the shed for use as a studio. So my recommendation is, if you want a shed, get a Tuff Shed, if you want anything else, build it from scratch.
