The units are constructed from sustainably harvested wood and have electric radiant floor heating and "a state-of-the-art, eco-friendly, incineration toilet"
(Although I've owned an incinerating toilet, and it wasn't that eco-friendly. It used a lot of electricity and created noise and some smells. But perhaps they've improved.)
But other than that minor quibble, this appears to be a truly "eco" resort. The owners say in Designboom:
"This is untouched forest, and we want to maintain it the same way. We decided, for example, to not offer snowmobile safari which is very common up here," says Selberg. Instead, wilderness walks will be offered.
