I love doodling, , working out a detail, This detail is not to scale, just a thought process to work out the joining of a new buildings brickwork to an older building with different sized bricks, and my way of divorcing the coursing between the old and new with a RWP, I like using a little colour. I have used this detail many times with great success, there are several different details to go with it, the ground interface, the eaves and a window and door alternative.
