pole building

[MarkP]

Aloha Rob. You mean a 15' post has 10' above ground and 5' below?

[Rob Tucker]

You could use that as a rule of thumb but design conditions above grade and soil conditions below grade can affect that... which is why engineering is useful.

We made octagonal concrete poles for a pole house some years back. The owner never did build the house and the poles became walls for a garden bed. Too bad. They were engineered for a two story dwelling and had notches for the beams with bolt holes cast in the appropriate places. I've seen a lot of pole houses but the wood part always made me nervous. Concrete poles would be the ticket.
