Scope
This was a retrofit that involved stripping existing house to the studs, removing all old plumbing and heating, and re-wiring. The exterior was stripped to the plywood sheathing and the cedar shakes that were removed are being re-stained and put back on building (lots of work, but worth it!)

Materials and Design Strategy
The exterior walls of this building consisted of vinyl siding that was placed on top of original cedar shakes. The vinyl siding was removed and installed on another house and the cedar shakes were removed and re-stained and replaced on original house. Before cedar shake siding was re-applied, 4 inches of polyisocyanurate insulation was applied over the water-resistive barrier (house wrap with taped seams). Then 5/8 " plywood was applied and finally a drainable housewrap.
All windows were replaced with triple pane windows and north facing glazing was minimized while optimizing south facing glazing
