*Important note to design trade & engineers. On all measurements from outside corner edges (including, heights, door sizes, window openings, distances from corners, etc.), they should all be devisable evenly by distance by 200 millimeters to avoid cutting small pieces of block and to avoid unnecessary expenditure. If 100 millimeters in height is required, an ashlar (one-half height unit) can be used or required for heights that are divisible by 100 millimeters. Also, 3 X 7 door sizes may fit both metric and Imperial Block Coursing.
