This was a great project . It is the only tree house to this day, I have ever had an order for ,so not much of a portfolio here . It is 16'x16' built to code .The tree is boxed out on the inside so the building is air tight and fully insulated .It is built around a Huge Shagbark Hickory but doesn't touch it even in the meanest winds the Catskills can serve up.(knock on wood ) .I got to say that another tree house project is somthing I am looking foward to.This tree house is sided with live edge white pine
