I have watched this technology develop, and the concept is brilliant on a number of fronts.
There are considerations people need to look at;
Will the cost of using it to save time, be worth the value of that time.
IE It may cost $3000 extra to build in 3 days compared with 4 months, but if it cots $11,00 it may not be worth it.
Setting it up will take a certain amount of time, perhaps its real advantage will in projects where multiple structures are being built
In some climates, insulating values of the walls are not important, but in others it will be a high priority.
I guess issues such as fitting it out with gas, electricity are all issues that will effect the final cost in cash and time, so different design standards may be better
IE All services may be bolted to the wall afce rather han buried or hidden within the wall.
I wonder if its best application will be in dense, high value
land areas and areas with poor assess.
IE London where access is expensive and hard to have.
Rather than open country side applications
