##Roofing
The roof system is built out of 2x6 rough cut rafters, suspended between a ridge beam and two beams mounted on the top of the north and south walls. The ridge beam is made from two 12' 4x12s combined with a half lap joint. The beam is supported under the joint and on the east and west sides by 12' poplar posts which were cut down to clear the site. 45-degree poplar sections connect the beam to the posts and provide extra support. The north and south beams are 14' 4x6s bolted to the north and south walls on top of the double top plate. The rafters angled towards each other to create a skinnier roof on the north and south sides than in the center.
The ceiling was built out of the same rough-cut boards as the subflooring and nailed to the rafters. We tacked roofing paper to the ceiling then covered the roof in overlapping corrugated metal roofing. We cut the edges of the roofing with an angle grinder.
##Future Steps
As of 12/16/2021 , the octagon was Tyvecked to be waterproofed for the winter. In the spring or future, the octagon will need plaster on the walls to protect the light straw clay insulation. One window still needs to be framed and installed in the top of the South-East wall. It would be good to add some kind of waterproofing or filler between the ridge cap and the roofing to prevent water from being blown upward and leaking through the ridgeline of the roof. Additionally, 2x6s need to be added to the outside of the floor joist triangles and flashing needs to be added to the bottom of the walls.
