When Designboom described this house in Poland, designed by też architekci, as "a stealthy and brooding presence" I thought that was for sure, along with some other adjectives. But the next sentence caught my eye: "the dwelling is entirely clad with dark thermowood." What's that?
ThermoWood is a Finnish product, sustainably harvested timber that is subjected to a three-stage heat treatment. According to their website, it is made from both hardwoods and softwoods, which both benefit.
