Actually considering building a "true" pole house....where the poles are integral to the structure. The treated poles are located so they are exposed to the exterior but covered by the interior finish. The floor is up off the ground by a couple of feet, so will definately need to be insulated. Otherwise a fairly straightforward square floorplan with cantilevered hip roof....the corner roof joists tag into the poles. Understand the benefits to concrete, including thermal mass, hydronic heat and all that, just reluctant to spend as much money as it will take to get our roads and access "concrete truck friendly", so we're exploring alternatives.
