Well a steel or metal buildings may not be suited for your home, but they are rather good in other uses like storage. Though I must say that some people do use them as their home. They do have their advantages – good quality, much lower maintenance cost, they are strong, durable, non combustible and pretty much good looking. But if the design and build is not good, you are looking at a whole deal of corrosion. So make sure that the work is done by an expert.
