My parents wanted a bench to go with the concrete fire pit that I made for them. I decided to reuse the wooden forms from that project to make the bench. The bench consists of two blocks of concrete made of Quikrete 5000 and three 8-foot long 4x6s that I got from the Home Depot. Four 4x4s would have worked just as well. I did this project in Southern California, so frost heave isn’t a problem, which is why I was able to place the bench without digging deeper. The wood isn’t actually attached to the concrete, but rather sits within recesses in the concrete blocks. I’m thinking about making the bench L-shaped in the future, so I wanted to be able to disassemble it if needed.
