criticism of a clever idea

This is hypothetical temporary dwelling that could be built using QuaDror prefabricated panels. There's more to the concept than this, and I will admit that the geometry is a lot more clever than anything I could come up with.
I am deeply skeptical of any architectural pre-fab solution. The issues of scale and joinery details tend to overwhelm any benefits associated with the cleverness of the design. And, as always, what about the site-work? Every project I've ever been associated with or seen or read about has had sitework issues that dominate the schedule, the budget and the initial and final architectural solution.
