Me and my wife are close to finalizing everything on the purchase of our first home. Unfortunately there is no space for my shop. There is an attached two car garage but not nearly as large as I need for the tools I have acquired over the last 12 months. The place I am renting now has a sizable 26×34 garage that I use for my shop. Therefore I am planning a shop build. I am thinking of a 30×40 or something close. I worked in residential construction in high school and have a very close relationship to my old boss. I am planning on doing as much of this construction as I can to help save money. My boss is also coming up to help. The garage will be block and stick construction (pole barn will not fit the style of our house or our neighborhood). Also I do not have a bottomless wallet and would like to keep the build as cheap, but quality, as possible.
My question is: is there anything I should be thinking about when building this shop/garage? It has to be a functional 2 car garage but my plans are to only use one bay for my work vehicle. Any wisdoms, wish I could have dones, wish I would have thought ofs before I commit and build? I live in Ohio so hoping to have heat/heat abaitment of some sort. I would appreciate any advice.
