At the present time, it appears that the end-choice will be a wood post frame structure, 24x36x10, steel clad. The extra 4 foot bay actually works out nicely to provide some structural support for a separate sound-reduced space for DC and compressed air as well as some storage needs. I'll not go into more detail than that for now as this is still something in flux, both from a zoning/permit perspective and a final contractor decision. The local power company is also being a pain at responsiveness as I need to work multiple scenarios to find the best solution, both functionally and cost-wise.
