In Practical Pole Building Construction the author has given the extra dimension of original plans for a lean-to barn, horse barn, hillside house, garage/wood shed, mountain pole cabin, and a coastal house.
Pole building construction saves money, time, labor, and materials because it involves limited grading, no excavation, flexibility on site, and few materials.
I originally bought this book because I needed a cheap barn and most people around my area build pole barns, but upon reading it I saw how flexible the building method is.
Combined with reciprocal roofs, pole building has the potential for very inexpensive buildings around my land.
