This builder has the walls and trusses prebuilt at a factory and brought to the jobsite on a truck. This is how they put them up so fast. Super said 10-11 days total to build garage and house.

Trusses are normally pre-built. My custom home will have pre-built trusses. It reduces the framing labor substantially. I'm sure they are saving big bucks on the pre-built walls too.
