Hi, I am building a single story extension with a lean to roof , I am constraint with height of the front wall of the extension because of upstairs windows to give 15 degrees roof pitch, with a French door in the front wall of the extension of 2mtr high, and a cantic type eaves lintel over that, my question is what is the minimum amount of bricks on the inner wall over the lintel is required, I cant find any information on this, with two bricks and a 50mm wallplate I can get 15 degrees pitch on the roof with a 150mm rafter birdmouth down to 100mm, is that OK.
regards Andy.
