How do you design a building with brick dimensions?

I'm designing a building which is going to have a cavity external wall, (brick outer leaf, insulated cavity and blockwork inner leaf). I need to design the building to brick dimensions and I have no idea how to do it as I've never done it before. Has anyone got any ideas on how to go about setting out the cavity wall to brick dimensions? what do i when I get to areas where there's a window or door?

Hi Windows and doors should be placed in your chosen positions but the building ideally should work out to brick lengths so imagine from the corner you have 10 bricks including 10mm joints to the frame and the same in height to the head of the frame for correct lintel installation . Brick manufacturers supply brick charts which show standard brick lengths and heights to various gauge ect . The cavity width should comply to building regulations in your area as the insulation width should have a u value to building control agreements .

Most bricks are 225mm long including 10mm joint so you can work out this way. Hope this helps.
