I'm possibly going to install a living willow fence in my front yard. In researching this two things have struck me. 1, why are there not more of these fences? I cannot recall ever seeing one in person. 2, what other possibilites present themselves in willow structure sculpture? I could not find a single real structure designed to serve a purpose beyond kid forts. Could you, for example, build a living stable to keep animals? How about a barn or a shed? I cannot imagine a greener building than one that is alive.
