Building a porch with 6” posts. I was planning on concreting them into the ground 18” deep like you would fence posts, but thinking may be better precasting some pads above ground then putting the posts on and building a brick plinth round it? Also seen various brackets available, mainly in 4” tho. Anyone done this and know a decent way? Appearance wise I’m not bothered if there is a visible plinth/base or if the post just goes into the ground.
