I live in a brick home with a stone foundation circa 1900. I want to
install board and batten over the existing brick.

To break up the board and batten I want to put 18" brick corners and
18" brick columns around the front door.

I was told I could fasten an angle iron to the existing brick to
support the new brick.

I was told to weld an angle to a plate 18" wide and 24" high, and
fasten this plate to the wall using concrete anchors. The angle would
only be supporting the weight of the bricks 18" x 8" high.

The existing bricks are concrete bricks not block. I was told the plate
would not pull from the wall as it was a static load and it is just
supporting the new bricks. Brick ties will also support the brick.

I am just wondering if anyone has any opinions or thoughts of this
system.

Thanks

Wouldnt the new brick need a foundation poured and tied by rebar to the
existing foundation, or it will sink and fall apart
