With fewer than a handful of functioning sod houses in existence, this would definitely be a National Historic Site worth visiting. In 1911, a carpenter from Britain by the name of James Addison built a substantial sod house near Kindersley, Saskatchewan, and he built it to last. The key was a permanent, quality roof to protect from the elements.
This documentary by Steve Wolfson, made in 2013, features Addison’s daughter, Edith Gardiner. At the time, Edith (who grew up in the house), still lived in and maintained this beautiful structure.
