There are so many examples of natural homes around the world. In the UK it seems every step you take, another earth gem rears out from a village street. Each inspires in a different way. Here's one from my home town of Wivenhoe.
For those who doubt the longevity of mud, the Garrison House dates back to the 17th century. It's a wattle and daub masterpiece, especially the pargetting in the earth plaster along the front. The wall has been coated many times over the centuries in lime wash, creating a thick, breathable shell which protects the plaster. Even the drainpipe has stood the test of time and is inscribed with the date 1678.
You can find more about the Garrison House from the Wivenhoe History website.
