Unlike the solid foundation of a traditional shed, the pole shed's foundation is made by simply digging a hole for each post, then filling in around each post with concrete.
Where a traditional shed has a floor of blocks or concrete, the pole shed has a natural dirt floor (although a crushed stone, concrete or timber floor can be added later if your budget allows.)
The most common roof styles on a pole shed are a gable or gambrel-style roof. A gable roof consists of two flat sections set at an angle to each other (commonly found on houses). A gambrel-style roof has two additional flat sections on each side (commonly seen on barns).
A very large pole barn shed may require a steel frame, but a smaller pole shed can be built with rough-cut lumber for the poles and beams, says the Secrets of Shed Building website.
Pole sheds are versatile, in that you can configure the space to meet your specific needs. You may wish to keep a large portion of the shed open, with a small part enclosed to store equipment and tools.
