Permanent Duck Blind Question

Depends on what you mean by permanent. What we call permanent typically gets taken down at end of season and rebuilt and possibly moved the next year. If this is what you're doing, you don't really need pilings. Use 10' 4x4s cut in half, and stick them in a about a foot so they stand up.

4x in a rectangular pattern, connect with 2x4's at ground level and top of post, lay plywood for floor. Wrap in burlap, then cover with your desired blind cover.

We always used roseau with willow limbs outside of that to break up outline.

Get some t posts and drive them deep. Then attach your would to those.

We have wooden blinds in my area that are over 70 years old so I would say they are permanent. I have helped build some that are 15 -20 years old now.

Depending on how big you want it you can get away with 2x4's. 4x4's are always a safe bet and will be as big as you will need. I don't know the style you intend on building so that would be good to know. Will it have a boat stall and shooting platform? A place to get out of the rain?

Regardless, we drive the pilings into the ground until they can't go any more simple as that. Build the shooting deck high enough so that waves can't crash over it. As for wood, just get non treated or scrap boards for floors and side walls. Paint them with several coats of burned oil to keep the bugs and rot out. I would splurge on treated lumber for the pilings and paint those with burned oil as well.
