We have seen the concept of housing from ISBUs explored extensively for several years now but they have yet to be produced successfully if you measure success by consumer demand that results in repeated duplication. If houses are ever produced that achieves a finish and shape that in no way appears to be shipping containers and does so at a very competitive price, I believe there will be a demand and that they will be successful. But if it was easily achievable it would have been on the market already. So many ideas have come forward and the fact that we can do so is one of the things that makes America great. Eventually an entrepreneur will figure out the right combination to make it happen.
