A bricklayer, which is related to but different from a mason, is a craftsman who lays bricks to construct brickwork. The terms also refer to personnel who use blocks to construct blockwork walls and other forms of masonry. In British and Australian English, a bricklayer is colloquially known as a brickie. A stone mason is one who lays any combination of stones, cinder blocks, and bricks in construction of building walls and other works. The main difference between a bricklayer and a true mason is skill level: bricklaying is a part of masonry and considered to be a lower form of masonry, whereas stonemasonry is a specialist occupation involved in the cutting and shaping of stones and stonework. Bricklaying may also enjoyed as a hobby.
