Solid wood panels, three heater technologies and checks before every cabin is packed.

Cabins are built from pre-assembled solid wood panels (Canadian hemlock or western red cedar) with carbon fiber, red glass full spectrum or ceramic heaters, or electric stoves. Checks: wood grade and moisture, panel fit, heater and control panel power-on tests, packing list verification. Third-party inspection welcome.
