Many people are very familiar with the work, writings, and contributions of Lloyd Kahn, the founding editor-in-chief of Shelter Publications, Inc. This photo came from a trip he took to Europe. It’s a little stone hut located on the southwest coast of Ireland.
What’s amazing about this little structure is that it’s constructed without mortar and was probably built around 200 A.D. The trick to its longevity was to fit the stones carefully together with careful attention to each concentric circular course. For me small structures like this define the words sustainable architecture. Photo credit Lloyd Kahn.
