>>11658465shipping container houses are very inefficient. the load points on a shipping container are on the corners. if you're doing anything but stacking fully intact containers directly in line with each other you're going to have to modify them big time. the sides are very thin sheet metal, even just standing on the top of them will dent them. they're also not very wide and make for very claustrophobic living conditions, and that's even without the additional loss of depth due to adding insulation. then when you factor in their immense weight and cost compared to a typical wood frame they are simply too expensive and impractical.
sorry to destroy all your hopes and dreams.
