How does electrical wiring and plumbing work in a tire house?
A. Tire walls (either rammed-earth or tire bale), before they are filled-in with plaster, have lots of grooves, slots and spaces for conduit runs, J-boxes, stapled-in Type EF wire (if no conduits are used) and switch boxes. In other words, wiring is done using standard electrical practices, before finishes are applied. Same way plumbing drains and supply lines, which are installed before floors are poured. Any other features would be exclusive to each design.
