What is the correct sequence for constructing a masonry wall?

• A. Corners To Center
• B. Bottom Up Without Reference Points
• C. Top To Bottom
• D. Center To Edges

Answer: (A)

Establishing the four corners first gives you fixed references that define the wall’s perimeter and keep it true in shape. By making the corners plumb and level, you set accurate length, width, and diagonals, which are essential for a straight, square wall. Once those corners are set, you run lines between them and lay the bricks outward from the corners toward the center, checking each course against the established references. This corner-to-center approach prevents drift—every course can be checked against the fixed corners to maintain alignment and straight edges as the wall grows. Starting without reference points, or trying to build from the center outward, tends to produce misalignment and uneven joints because there’s no solid boundary to guide the wall’s true shape. Building from top down isn’t a typical sequence for masonry walls either, since you need solid, referenced footing and corner lines to guide the rest of the work.
