This mailbox is simple enough to build with enough time on hand! The whole build used 4×4 and 1×6 lumber that you can purchase right from your nearest home improvement store.
Okay now on to the build –
I cut all the wood according to the cut list below using a compound miter saw. You could also have your local home improvement store cut your boards for you. Please keep in mind that straight end cuts are very important to keep everything leveled.

TOOLS
I had the original post from my old mailbox already in place, It stood around 37 ½” high. I used this as my starting point for my front post. I measured around 16 ½” from my front post to where my back posts would be factoring in my mailbox dimensions.
Here is the beginning of the hole for the other two posts. I opted to go with a concrete pour instead of a concrete pad. I dug the hole around 12 inches deep. You can opt to go deeper but keep in mind the cut measurements will change.
