Using fence posts instead of structural posts?

[perky416]

Hi Guys,

I am about to embark on constructing a car port style structure to house a golf simulator in the back garden.

It will basically be x4 upright posts with a flat roof (timber joists with bitumen sheets). The size will be 2.8m high, 6m long and 3m wide.

Now I know this is a silly question, but I will ask it anyway. Can I get away with 150x150mm treated fence posts, sunk 60cm in concrete?

Structural oak posts are 150% more expensive. Im hoping is it is more of a shelter style construction i can get away with using the fence posts.

Thanks

Wooden posts ALWAYS rot at ground level. However, yes you could get away with standard timber posts. You just need to mitigate racking and wind load when building it. You will need about 800 in the ground with a 3m tall structure.

Thank you.
One side and one end will be shielded by neighbours fences for about 2/3 of the height.
At the other end the posts will be sitting flat to my concrete garage. I may bolt the posts to the garage to add extra support.

At that height I think you'll need planning if less than 2m from boundary.

Use fence post protectors - they stop rotting at ground level
