Sustainable Hobbit-Style Turf Homes
The 1960s was the time when the first modern green roof structures appeared, but it is worth mentioning that Scandinavian people have been living this way for millennia.
The adorable hobbit-esque homes across Norway, Iceland and other Nordic Islands were mostly built out of sod.
Sod offered an insulating layer to rooftops and walls, and it proved to be the best solution in these northerly places, being also an abundant resource, easy to install and maintain.
With a roof made of sod, these homes were made weather-proof due to the fact that it was used the bark of native birch trees, which was collected in spring, when the upward flow of sap made the bark easy to peel from the trees. Thus, due to this bark, the sod roofs has a lifespan of about 30 to 40 years, similar to the synthetic rubber liners we use to prevent moisture from damaging the roof.
