Hi All.
I am looking to build a 12 x 12 out door shade structure. I am going to build a hip roof with four columns that support it. I would like to build columns that have a stone veneer about 6' up with an 8"x8" coming out the center to use as support. I am looking for the most economical way of making this. I was thinking of framing the column and using OSB for sheer. Does my 8x8 need to go all the way to the ground to provide the strength to support the roof? How can I make this happen? My other option was cinder block columns, but I was not sure how to attach the roof to these either. Any help is greatly appreciated.
Thanks
Side note - I have 18"x18' by 12" deep footings in the patio concrete. I was thinking of some sort of anchor bolts/simpson ties.

I live in Northern California. No snow in my region, just wind, rain and hot summers.

Something kinda like this (but much prettier )
or this

Hard to answer without knowing what region you're in. Do you need footings below frost level? What snow load must you design for? Will the hip roof be tied at the bottom to resist any lateral forces?

I see no way just using any type of post base and that small a footing is going to hold that load and not sink and also stop it from side sway.
Also using one piece 6 X 6 or 8 X 8's is going to end up checking, twisting, or curling at some point.

Each footing would be carrying about 1500 pounds, and the bearing area of each is 2.35 square feet...that's a soil bearing load of 666 PSF...I can't imagine a soil which would fail to support that load.

Notice that both the examples shown have knee braces at the column to roof connection, which will resist lateral forces. A post base and anchor bolt atop the masonry piers only needs to resist uplift.

Placing tongue firmly in cheek.....Gee, this is a boring, factual, and helpful posting. I think I can help fix that.

Perhaps you should consult a structural engineer. You know, a professional; someone whose superior intellect and ability to look up numbers in a book have not been cluttered by such trivia as hard-earned, hands-on experience, the ability to communicate effectively, and people skills.

Since you do not have the habitual snow load problem, your biggest problem will the seismic and alteral stability in addition to code compliance.

You said "northern California" which does not give much information since there are many local problems with wind and seismic conditions that do not show up on a map.

A quick check with your local building oficial may be worthwhile since they usually recognize the "enclosure" permited as a step to an addition and the unseen future problems with compliance and resale problems.

Your footings are minimal and may not have been designed for what they will see.

You will definitely have to make sure you have lateral bracing for the structure (footing fixity, diagonal braces, etc.) depending on what the top/roof structure and height is. No one likes the look of braces, but somehow the structure must be stable for the conditions. Only a professional can help you through what you might encounter in the future.
