By Ashley AndersonDecember 10, 2025

Transforming your outdoor space into a cozy and functional retreat is easier than you think. One way to achieve this is by creating a DIY bench using concrete blocks and wood. This combination not only adds a rustic charm but also ensures durability and longevity. Let's dive into the step-by-step process of creating this perfect blend of raw and refined materials.

Before you start, ensure you have the right tools and materials. You'll need concrete blocks, pressure-treated lumber, gravel, sand, cement, a trowel, a wheelbarrow, gloves, safety glasses, and a tape measure. Having these ready will make your project run smoothly.

Preparing the Base: Concrete Blocks

The concrete blocks will serve as the sturdy foundation for your bench. Start by laying them out in the desired bench shape, ensuring they're level and stable.

To secure the blocks together, you'll need to create mortar. Mix cement, sand, and water in a wheelbarrow until you achieve a consistency similar to thick peanut butter. Apply the mortar between the blocks, using a trowel to ensure an even layer.

Laying the Blocks

Begin laying the blocks in a staggered pattern for added strength. Apply mortar on the ends and sides of each block before placing it. This will help create a solid bond between them.

Once you've laid the blocks, use a level to ensure your bench base is even. Allow the mortar to cure for at least 24 hours before proceeding to the next step.

Adding the Seat and Backrest

Now that your base is secure, it's time to add the wooden seat and backrest. Measure and cut your pressure-treated lumber to fit the dimensions of your bench. Ensure the seat is at a comfortable height, typically around 18 inches from the ground.

Attach the seat and backrest using outdoor-rated screws. Drill pilot holes first to prevent the wood from splitting. Once attached, you can stain or paint the wood to match your desired aesthetic.

Finishing Touches: Comfort and Style

While concrete blocks provide excellent support, they can be quite harsh to sit on. To add comfort, consider adding outdoor cushions or a wooden slat seat.

For an extra touch of style, you can create built-in planters on the sides of your bench. This can be done by adding a few extra concrete blocks and filling them with soil and your favorite plants.

Cushions or Slats: Adding Comfort

If you prefer a cushioned seat, measure and cut outdoor fabric to fit your bench. Attach it to a piece of foam, then secure it to the bench using Velcro or ties. This will make your bench a cozy spot to relax.

For a more rustic look, you can create a slat seat by attaching thin wooden boards to the top of your bench. This not only adds comfort but also complements the natural look of the concrete blocks.

Built-in Planters: A Touch of Green

To create built-in planters, simply add a few extra concrete blocks to the sides of your bench. Fill these with a mix of gravel and potting soil, then plant your favorite flowers or herbs.

This not only adds a pop of color to your bench but also helps to soften the harsh lines of the concrete blocks, creating a more inviting space.

There you have it! Your DIY concrete block and wood bench is now ready to serve as a focal point in your outdoor space. Whether you're enjoying a good book, a cup of coffee, or a chat with friends, this bench offers the perfect blend of comfort and style. So go ahead, put your feet up, and enjoy the fruits of your labor.
