wondering if I can leave the current concrete patio/pad to build new wood patio cover, or best to tear out and re-pour new concrete FOUNDATION < if I also plan to enclose the patio with framed knee wall + windows all around.
2 projects that are related. In Los Angeles, CA area
#1 New patio cover. Currently have an 20yr old light-weight metal patio cover over concrete pad. The 3 metal columns look like this pic (not my house but same exact style columns) columns are attached to concrete with small metal ties.
If i want to replace the patio cover and build w wood beams, tied to house with ledger board and 4x4 wood posts...Safe to say I should make sure to have footings for the columns at that point. So retrofit the current pad w footings or place footings outside the current pad (extend to the grass a bit)
#2 I *might* want to enclose this patio decently with framed knee wall + windows, drywall the ceiling maybe... if so, should I rip out current concrete and get proper foundation poured. At that point it becomes more like a room addition. trying to avoid if I can frame walls and enclose on top of current concrete pad.
