Hakan, of Urnatur, built this cabin in the
woodland where he lives. Together with is wife Ulrika they run
courses in cabin building using traditional skills and natural
materials and other workshops in fence building, wild herbs and
woodland skills like harvesting birch sap. He used birch bark
under the turf roof for the moisture barrier. A green roof like
this will last about 30 to 40 years. Birch bark was the prevailing
roof type in rural Scandinavia up until the mid 19th C. The green
roof came about by accident because the turf was used to keep the
birch bark flat and in place. In Finland it was more common to
place lengths of wood over the bark. The sheets of birch were held
down with the very logs they were removed from. |
