Tree House Marin California

We solicited entries from readers on The Big Event and in this Sunday Datebook cover story profiling a few local tree house builders. There werent a lot of rules. Tree house purists will say that anything without a roof is just a tree fort for this contest two planks balanced on a tree and a healthy imagination a perfectly fine tree house. We also accepted a few houses from beyond the Bay Area from transplants or Bay Area residents who built on a vacation home.
