Below sees after three layers are in place. the side will look better after pointing. The courses all have different bonds and overlap joints. It feels like a cast reinforced concrete slab.
Cleaning up some plaster.
From the top looking down. It would be better to have joints in the middle, but these are thin bricks and cutting makes them a bit weaker. and it is covered of course. I walked up the vault. feels more solid than a full single brick in shiner orientation. I mean it feels very solid, like i said like a reinforced concrete beam.
