Decide where you want to place your bench, and determine how large you would like it to be. Mark off the length of the bench.
Before beginning any excavation, call 811 to check for underground utilities.
Dig two 24-inch by 24-inch square-shaped holes 6 inches deep where you plan to place the pillars. The first courses are buried in order to provide greater stability.
Once the holes are dug and level, pour in paver base about 3 inches deep and tamp until well compacted.
Lay the first courses, leveling as each stone is placed. Use the remaining base to level and fill in the first courses.
Rotate the pattern 90 degrees for each course. Use landscape adhesive on each course if desired. (note: this will require more tubes of adhesive.) Check for level after each course. Continue until you complete the fourth course.
Change the way the fifth course is designed by only laying block on the half that faces away from the other pillar.
Measure the distance between the two pillars, including the empty slots on the fifth course.
Construct the seat using eight 2 x 4s cut to the distance measured in step 7. Cut additional 2 x 4s into 14 blocks, each 4 inches long. Use seven blocks on each end of the seat to space the seat boards. Secure the spacers to the longer boards with 2-1/2-inch decking screws.
Use a waterproofing sealant or stain on wood and allow to dry.
Complete construction of the two pillars.
Wall block sizes vary by style and market. Use the quantity in the material list as a guide. Also, when purchasing wall block, remember that some block has an interlocking lip on the bottom for use in retaining walls, not stacked block projects.
