Amundsen had hired a young local carpenter, Jørgen Stubberud, to work on his house at Svartskog, and was impressed enough to ask Stubberud to build the expedition hut, capable of being built ahead of time and reassembled on site. "Roald said only, 'It should be winter quarters, five metres long, four metres wide, and five metres high. Figure out the rest yourself!'"
"So then I went to Skedsmo and got the right materials, three-inch plank. There should be four panels, two outside and two inside, with cardboard in-between. I finished 'Framheim'. Roald said he was pleased, and so I packed the whole thing up. Afterwards I asked respectfully, "Captain, is there also an opportunity for me to go with the expedition?' 'Yes,' answered Roald, 'as long as your wife agrees.' And she did right away. The same day I sat in Roald's dining room and signed a contract for seven years."
