The cedar posts should give it a natural look. It'll be interesting to see the finished product. You call this a "shooting house", I can't recall hearing that one before, around here it would be a hunting blind. Is that a common term in your area, like here in Pennsylvania we drink soda, but in Wisconsin they drink pop?
I'm thinking about building a shooting house with locust tree poles.
I have a pole barn on property built in 1940 with locust poles in the ground that are as solid as ever.
I've heard cedar poles last a long time too but they are not common around here.
FL Plotter cedar last a long time. The white part of the post will rot away over time. The red part of the post will not rot easy. This are about 15 inches in the ground. The red part is about 9-10.
I know cedar post you buy at lumber yard don't last at all.I would be worried about nailing or screwing to those post.The main frame needs to be bolted as there will be some movement
