Taking apart our mid-century in preparation for the major renovation has revealed a lot about how these homes were built. From construction techniques to mangled wiring and plumbing to termite damage, the truth is exposed when you open up the walls.
There was some thought put into the original design. See examples below.
Diagonal boards went under the siding to provide more shear strength to the walls so the house wouldn't “rack” or begin to lean over.
In the master bedroom the plumbing wall was thickened so that the vent pipes would miss the beam to extend through the roof.
Most of the rafter beams do not span the full width of the house. Strategically placed in walls, they were supported and then spliced together.
