I’m going to build a pergola sometime next year for the back of my house. I prefer not to use a band board on the house for carrying the ends of the horizontal boards.
I’m kicking around the idea of fabbing out steel brackets, maybe even decorative, lagged into shields. I can access a plasma cutter and can float a decent bead so the brackets could even have a bit of design.
I’m also thinking of cutting shallow pockets (1-1/2″) into the brick, with an air chisel, and setting the ends into the pockets.
