I am going to build a canopy measuring approximately 4 x 3 meters. The roof will be made of rough-sawn boards and standing seam metal roofing, which is relatively "light." I need to attach a load-bearing beam (like a 45 x 145 beam) about 4 meters long to the house wall, approximately 3 meters up from the ground. I will then attach the roof rafters to this beam. The problem is that the house wall consists of facade brick, 45 mm insulation, an old masonry finish, and inside, a THICK tongue-and-groove plank wall (from the 1930s). The backside of the house wall, i.e., the inside, is an accessible attic. How do I securely attach my beam to this wall? Is it even possible? Using plugs and screws only in the facade brick feels risky. Putting in a long French wood screw reaching the thick plank wall also feels risky. Likewise, using threaded rods straight through the brick and plank wall seems risky. There would be a "bend" against the brick facade when tightening the whole thing. The alternative to attaching the beam to the wall would be to use standing beams (posts on footings) from the ground, on which I can lay my beam, but that would be aesthetically off. Additionally, it’s newly drained with gravel around the foundation, so a poured footing wouldn’t be ideal. Help me, friends!
