UO Architecture grad Carol Venolia, Healing Environments author, spoke here once saying it can take 20 yrs for a new house to outgas. Id make sure minimum toxic* finishes used (SafeCoat makes sealers that can seal plywood, even carpet chemicals). NAUF no added ureaf. plywood could be used. All paints are supposedly low VOC now, but _no_ VOC may be preferable in tiny homes? (Hempcrete would not need paint.)

(*Minimum toxic is sometimes the preferred vocabulary because non toxic may not apply to everyone: e.g., some are allergic to cedar, etc.)

WiFi if siting lots of homes near each other: could be health issues. Eco WiFi apparently reduces RF/MW by 80%, works in the US: made elsewhere. I'd hope that communities, people in regular houses, would get into habit of turning off routers at night. I dont use WiFi.

RE 75k price: I know a man building one, he estimates 25k, some to a friend. But I do not think that it is up to code since not codified? He doin the bldg, and not arch designed.
