When it comes to cost rebuilding, we can't compare the software engineering with other industries(like cards or buildings). I think this makes it much more iterative compared to them. Living in North America, if feel like 99% of aparatments and houses can be grouped into 5-10 floor plans. I think thats because when you are designing a new building or house you really can't do much risk. You do what has already worked. Software also have trends, but they change so often. You also can't do A/B testing or targeting or measure every single interaction potential customer has with your product. The nature of building "Software" really brings so many options to the table which increases the number of iterations by order of magnitude.
