I know there ugly but I dont see why vinyl siding and a conventional roof wouldnt make it look like a normal buiding
Ive seen a few models on a german website but they are just painted and dont look that bad. Some countries are using these over conventional buildings. I considered buying three 20' and making the garage door on the side thus giving me a 20x24 space. These things have a hardwood floor in them so I wouldnt really need a concrete floor, just throwing some ideas around I guess. I came across a website a few months back and a 20' with fresh epoxy paint was going for $800 much cheaper than the local barn builders who want 20-25k for a similar sized building
