Ok. I have an old 30x30 pole barn where my boat tractor lawn mowers atv.. Etc live. I plan on putting a concrete floor in and clearing out my attached garage for only cars stuff. Making a shop. But it is small and I would an going to see if I can get financed to build an actual shop. So my question is for those of you who went through the process of having a garage/shop built. What are the pros/cons and opinions on likes and dislikes of the different build style options. Concrete slab with a steel truss building, pole barn finished with concrete poured floor or a conventional garage stick built with 2ft block or poured concrete footers ?
