DIY Cinder Block Bench

One of our annual family traditions is to chop up our Christmas tree after the new year and have a bon fire in our backyard with some S’mores and hot cocoa. We have a patio in our backyard with a steel fire pit that is perfect to host this tradition, but this space has always lacked seating for all of us.

Yesterday I went to Lowe’s to find a solution and I am so happy with the results! I’ve seen other cinder block benches before, but the design I came up with will cost you less than $30 to construct! And the hardest part about this project was loading and unloading all the cinder blocks in and out of my car. Simple, custom seating for less than $30?! Yep, here is how to make a cinder block bench:

*I originally had another plan in mind when I was buying my supplies, but you could swap the (4) 2×4’s with (2) 4×4’s. It would be even sturdier and maybe cheaper.


  1. Start by building your bench posts, or legs. Each cinder block post is going to use 3 blocks- 1 horizontal block laid directly on top of 2 vertical ones. Space each post to your liking, or to fit your cushions. My posts were just under 2 feet apart from each other.
  2. Feed the planks of wood through each of the top holes of the cinder block, as pictured below:

  3. Now that your wood is in place and to your liking, secure it to the blocks by applying some liquid nails. Truth be told, I didn’t do this step. The bench feels surprisingly secure and I was running out of daylight. I told myself (and my husband!) that I would secure it later, and I just haven’t gotten around to it! I definitely need to secure the molding on the bottom ’cause they keep falling flat, but the wood planks don’t wiggle too much, so I am not in a hurry to do anything about it. (<< DIY according to Stephanie!)
  4. Optional Steps: Paint your beams and your cinder blocks and when they are dry, add some cushions. If you have molding, feed 1-2 pieces through the bottom holes and secure with adhesive. These options are purely cosmetic.
