Straw Bale Structure Almost Finished at Summit House

We are almost there… the roof is taking form!

A roof bearing assembly, or box beam, sits above the box columns.  It is constructed of a double 2 x 6 for the exterior perimeter and a single 2 x 6 for the interior perimeter.  The underside of the beam will be sheathed in plywood to act as a fire stop for the wall.  The box column will also act as a nailing strip for the plaster mesh applied over the bales.  The trusses will sit above the roof bearing assembly.

The trusses are up and the fly rafters are being constructed over the drop end.

Plywood sheathing is next.

Progress Continues at Summit House

Bruns Construction continues building the structure for the straw bale shed at Summit House…

Box columns are up!

The box columns are constructed of a double 2 x 4 on the exterior and a single 2 x 4 on the interior of the column.  15/32 plywood is used to sheath the boxes on both sides.  Plywood is used, as opposed to OSB, because it will stand up to moisture better if any water were to get inside the bale wall.

The columns are as deep as the bales and sit on the base layer of sills and between the second layer of sills.  They are bolted to the sills and the foundation (two per column) with 7″ x 1/2″ anchor bolts.

The first column to go up will frame the double door.
