What procedure should be used to install a flagstone patio?

• A. Start in the middle and work toward edges
• B. Start at the edges and work toward the middle
• C. Start at one end and work towards other end
• D. Start at the high point and work toward the low point

Answer: (B)

When laying a flagstone patio, you want a clean, defined border to work from. Establishing the outer edge first gives you a stable frame and a reference line for aligning stones and keeping even joint spacing. As you work toward the center, you can trim stones to fit the border precisely and ensure the finished edges look neat.

Starting in the middle can make it hard to form a straight, even edge later and may lead to awkward cuts near the perimeter. Beginning at an end and moving across can make it harder to maintain a true border line without a reference. The idea of starting at the high point and working toward the low point is about drainage grade rather than the layout of the border and edge control. So the best approach is to start at the edges and work toward the middle.
