Opinions on this Permanent Wood Foundation Assembly
Hello, first time poster here! Looking to see if there are any problem areas with this assembly.
I’m playing around with a wood foundation assembly based on Mike Guertin’s suggestions from his 2020 presentation. This would be for a self-build DADU a few years in the future. I’m planning to get an engineer to sign off on everything, because this is a lowish seismic area and I’ve never built a house, just done extensive remodeling and a Habitat build.
• Zone 3A, mixed humid climate, bordering Zone 4.
• Carolina clay, gently sloped site.
• Termites, water, and radon intrusion are the biggest concerns here.
• I didn’t write it down, but the rain screen would be wrapped top and bottom with a screen to keep out pests.
• I threw the inner ZIP sheathing in there as an additional fire/seismic precaution, not certain if it will be necessary though.
• This shot is of the crawlspace; the main wall assembly is different, based on the Bonfiglioli design. The roof plans are a bit unusual, with large applied eaves, so if there’s any interest I could post them as well.
• I’m aiming for near-passive performance, but not currently planning on getting it certified.
If you have any questions about details I’ll happily post better drawings!
