Very indpiring!
Pros:
No cement or mortar used
Water recycling modules
Rain water harvesting
Energy efficient
Bio gas integration
Cheap
Cons:
Although this design uses 19% less walls, it limits the vertical expansion. These days real estate is very expensive to not to opt for multistoreyed construction in cities.
I doubt the effectivity of thermal regulation with climate variations as thickness of the wall can't be altered once constructed.
