I suppose depending on how rural your new home is will dictate the building permits. They are nonexistent out in the sticks here in central Mississippi. Might I suggest building a lean-to structure. Depending on your lots size, you can add on to a lean-to with ease. It can be widened by building another stall and by building onto the high side of the pitched roof, making it a two pitch roof like most homes. Crushed granite or pea gravel is in my mind best for the floor due to it's forgiveness of the sore feet syndrome, not effected by moisture, and keeps you from tracking in dirt into the home leading you to having to sleep in the smithy.!! Lol. The more light the better. I wired my smithy with 3 rows of lights. Each row on a separate switch so I can shade any part of the shop for accurate metal temp colors. Good luck!
