Some of the bales needed to be customized to fit into angles in gables.

Bottom bales fitting into wallplate needed to be notched. Note vertical timber for horizontal compression.

Vertical compression.

Anchor. Screw eye in brick masonry with polyester strapping to tie the bales tightly to exisitng wall.
