Dewatto House

I decided to arch the doorway to the porch and match it with a window opening in the porch. I cut an arch shape out of plywood for each and used the plywood for a template to scribe into the ICCF. I cut from each side with a sawsall and then finished the cut with a hand saw. By far the least messy method I've used.

Both openings were then bucked out with 1/4" masonite flexed at the top. The plywood template was then placed back under the masonite to hold it in place. Cleats were attached to the door jambs to hold the plywood tight, and the whole thing was tacked in place with construction foam. Because of the roof slope, there's not much concrete above these arches.
