I'm wanting to build a 3 sided single sloped pole shed and I am having trouble coming up with pole ideas. It will be 12 x 24 with a total of 6 poles so I can have 12 feet openings in the front. Normally you bury a post in the ground and build the thing but that's where the problem starts. Some like it dug down 4-6 feet and put in gravel, some in a sona tube, etc. I have even looked into those techno posts that are screwed down which are cool but expensive. I would also like to see what it would cost to drive in metal pillings. Does anyone know who does that down on the Kenai? I'm down by clam gulch. The ground I'm in is gravel/sand and on a small knoll so I have pretty good drainage. Am I over thinking this? Original plan was to drill a hole drop a rock or pour a bottom plug and bury post back with gravel. I was told it would frost heave and post would rot after 10-15 years. Same with sono tube. I guess driving down a steel post would take care of that if its not too expensive.
