This is anything constructed from bricks which are normally fired clay, yes we are really still building from mud! The small size of the individual bricks makes brickwork and incredibly flexible building material to make garden structures out of.

A few points to note:

• The thickness of a brick wall is described relative to the bricks length so the wide of a wall goes up in half brick steps starting with a ½ brick.
• The mortar between the bricks is there to keep the bricks apart and stop them wobbling, it DOES NOT STICK the bricks together! In fact to an engineer brickwork has no tensile strength, that is to say it has little or no strength when being pulled apart.
• Most bricks have little resistance to frost when wet so unless engineering bricks are being used things like retaining walls will need to have the brickwork protected from moisture.
