Build a Mailbox With Patio Blocks

Mailbox Built With Patio Blocks

Get an old-world look and lots of curb appeal with a do-it-yourself mailbox using wall blocks.


Build Your Mailbox

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.

Step 1

Dig a 30-inch-by-30-inch square-shaped hole 6 inches deep. The first course is buried in order to provide greater stability.


Step 2

Once the hole is dug and level, pour in paver base about 3 inches deep, and tamp until it's well compacted.


Step 3

Lay the first course, leveling as each stone is placed. Use the remaining base to level and fill in the first course.


Step 4

Rotate the pattern 180 degrees for each course. Use landscape adhesive on each course if desired (Note: This will take more than two tubes of adhesive). Check for level after each course.


Step 5

After the 10th course has been set, anchor the mounting plate to the block with concrete screws to attach the mailbox.


Step 6

Place the mailbox on the mounting plate using wood screws. Then set two stones running front to back snug on both sides of the mailbox. Repeat this step two more times with courses 12 and 13, until the mailbox is fully enclosed.


Step 7

Turn the 14th course horizontal, and finish the final (15th) course by centering the stones horizontally across the courses underneath.


Step 8

Attach the address numbers and flag.
