Ashlar Masonry uses which type of stone units?

• A. Irregular rubble stones
• B. Circular stones
• C. Brick blocks
• D. Stone cut rectangular units

Answer: (D)

Ashlar masonry relies on carefully cut, uniformly shaped stone blocks—usually rectangular or square—dressed on all faces and laid in even horizontal courses. This precise shaping creates clean, tight joints and a formal, orderly appearance. That’s why the stone cut rectangular units are the correct description for ashlar. Irregular rubble stones are used in rubble masonry, circular stones aren’t standard masonry units for ashlar, and brick blocks are clay-based units, not stone, so they don’t define ashlar construction.
