Yes it is interesting! Too bad the roof design appears to be fundamentally flawed. It looks like the interior ties do not have rafters on them so most of the roof thrust is landing on the plates and they appear (pic. #2) to be rolling outward.

The double tie is very curious. In his book The Pennsylvania Barn, Robert Ensminger has recorded double tie beam construction in Sweitzer barns, but this is a different style.

How can you tell that the plate is interrupted?

Thanks for intriguing us!
