You hear about Leave No Trace in reference to hiking and camping, but it isn’t something a lot of people think about when referencing architecture. Norway's Flokehyttene cabins are a different story.
Embedded in the rocks of Sveio off the Norwegian coast, the five timber cabins are the creation of HOLON Arkitektur, which designed them with the rugged coastal landscape and its harsh elements in mind. Commissioned by a branch of the Norwegian Trekking Association with a directive tied to sustainability, each cabin has minimal impact on the ground they're set on. If they're ever taken down, the only proof of their presence would be the four drill holes in the rocky shore that support their legs.
