Next I cut the voids in the walls. This greatly saves on weight and allows space for the insulation and wiring.
Cutting the voids out with a router. Make sure you are aware of the saw horses underneath for every cut and be sure to have something to catch the falling pieces so they don’t bonce back at you while you have the router running.
After the first wall was complete I used the first completed wall as the template so I was able to mirror them perfectly.
I was worried about the rigidity of the sidewall with all those holes but it still feels quite strong and much lighter!
Taking a break to dryfit the sidewall to the deck.
