What is the correct method for constructing a masonry wall to ensure alignment?

• A. Corners To Center
• B. Center To Corners
• C. Bottom To Top
• D. Top To Bottom

Answer: (A)

When you want a wall to come out true to plan, you start by fixing the two corners. Those corners define the exact ends and the overall length, giving you solid reference points to guide the entire run of masonry. A string line or straightedge is stretched from corner to corner along the intended face, and you lay bricks toward the center while checking that the line remains true. This setup makes it easy to spot and correct any deviation early, so the wall stays straight and squares up with adjacent lines.

Starting from the center or building from top or bottom without anchored ends invites drift because there isn’t an unambiguous, fixed reference to keep the line true across the whole length. Center-to-corners or other methods can lead to cumulative errors that are hard to correct once you’re past the early courses, whereas corners-to-center uses the corners as the reliable framework for alignment.
