If it a permanent structure, especially an open sided structure, you need a foundation. You don’t need a traditional footing, all you need is correctly sized denotes set 4’ below grade. Say you used 4 corner posts, 6x6 needs a 10” sonotube 8x8 needs 12” tube. Don’t use 4x4.What happened with footings?
I kicked around the thought of a simple roof over the BBQ but got informed, hopefully wrongly, that any raised deck or roof structure needed massive footings and posts.
What happened to a drilled hole, shovel of crushed stone and a concrete filled Sonotube with a 4X4 PT post?
Digging for a 300 X 300 mm footing is a ton more work than a 12" drill and fill.
Open sided structures are trickier to build safely. Without walls, wind creates incredible uplift and twisting forces on roofs - so good anchoring is important - to the ground and the roof to the frame.
You want a bbq shelter, not a kite.
