Abstract: The present invention provides a guide for constructing brick corners in which the corner is constructed from a plurality of stacked brick layers which are spaced apart from each other by a joint. The guide includes at least one guide bracket having two wall sections which intersect each other at the same angle as the sides of the corner and the bracket is positioned against a partially constructed brick corner so that the wall sections flatly abut against opposite sides of the corner. A lip is formed along the top edge of each wall section and the lips are positioned on top of the top row of brick in the partially constructed corner. Several further rows of bricks are then laid on the corner so that the lip, and hence the guide bracket, is trapped within the joint between two brick layers. A pair of elongated rails are secured to the bracket so that the rails extend vertically and parallel to the corner.
