I am at the very start of a project to convert a carport which is attached to my garage into a beer cave. The dimensions are 22'4" by 15'8". I brew with a 10 gallon more beer sculpture using propane but I am thinking about at least putting in the capability to go electric. The floor is currently asphalt which is very uneven. Any suggestions on layout, what to do about the floor - replace?, ventilation design, heat resistance for the wall near the kettles?, etc would be greatly appreciated. Thanks!
