Sturdy Outdoor Bench You Can Make Using Cinder Blocks

Looking to add customized, contemporary seating to your backyard or patio? Building your own outdoor bench from cinder blocks is an affordable DIY project that can create a stylish and sturdy addition to any outdoor space.

Let's get started!

Materials You'll Need

One of the best aspects of this project is that the primary components are inexpensive and readily available.

Cinder Blocks

Cinder blocks provide the supportive base and contemporary visual appeal of the bench. They can often be found affordably on sites like Craigslist, or purchased new at home improvement stores. Some tips:

• Choose blocks with flat and smooth surfaces to allow the wood slats to lay evenly across the top.
• Standard 8" x 8" x 16" blocks are a common choice, but larger blocks can provide more seating space.
• Calculate how many blocks you'll need based on desired size and layout.

Wood

Wood slats or plywood panels create a smooth, comfortable seating surface. Considerations include:

• Opt for exterior-grade plywood at least 3/4" thick to properly support weight.
• Seal and waterproof wood prior to installation for longevity.
• Cut pieces to size with a circular saw for a custom fit.

Outdoor Fabric

Durable outdoor fabric covers foam cushions for a cozy feel. Look for:

• All-weather fabrics like polyester or treated cotton.
• Matching thread and stitching designed for outdoor use.
• Enough yardage based on cushion dimensions.

Foam and Batting

Layers of foam and batting pad the bench:

• High-density foam prevents sagging and indentation.
• Polyester or cotton batting options depending on climate.
• Combined thickness of 4-6" for comfort.

Other Supplies

• Staple gun for securing fabric
• Scissors for cutting fabric and batting
• Paint and primer if staining blocks
• Shovel for leveling and prepping the area

Planning the Design and Layout

Once you have your materials, it's time for the fun part - bringing your vision for the bench to life! Consider the following:

Size and Dimensions

First, measure the space where the bench will be situated. Factor in desired seat depth (16-18") and backrest height. Decide on straight or curved shape.

Structural Considerations

Determine the cinder block arrangement that will provide the most stability. Using concrete adhesive between blocks prevents wobbling. For extra reinforcement, bury blocks or anchor wood into the ground.

Personalized Style

Customize the look! Play with different block styles and colors. Add decorative accents like tiles or planters. Get creative!

Step-by-Step Building Instructions

Once the planning stage is complete, it's time to start building your cinder block bench. Follow these steps:

Prep the Site

Level the installation area with a shovel. Dig holes to sink blocks if burying for added stability. Add a 4-6" gravel base for drainage if the bench will be in a high moisture area.

Assemble the Block Foundation

Stack blocks according to your determined layout in a staggered, overlapping pattern. Apply concrete adhesive between layers for reinforcement. Leave 1-2" channels for inserting wood supports.

Add the Wood Supports

Cut wood slats or plywood top pieces to size. Seal and coat wood to weatherproof. Carefully place into block channels, securing into the ground with landscape stakes if needed.

Make the Cushions

For each cushion, cut fabric larger than the dimensions to allow for seams and stapling area. Sew fabric together, leaving one side open. Stuff densely with foam and batting. Staple excess fabric to the underside of the wood.

Final Touches

Almost done! Paint or stain cinder blocks if desired. Add any decorative accents you've selected like planters, tiles or lighting. Protect the bench from elements in winter if needed.

Customization and Design Ideas

While a simple cinder block bench is stylish, you can make it your own with unique custom details:

• Paint or stain blocks in vibrant colors like turquoise and yellow.
• Alternate different block shapes and textures.
• Attach corner planters to each end filled with colorful flowers.
• Stencil fun patterns onto blocks with exterior paint.
• Incorporate lighting like solar path lights or LED strips.

Get creative with shapes too. Curve bench edges, build it circular or incorporate L-shaped corners. The possibilities are endless!

Choosing the Right Location

When choosing where to install your DIY cinder block bench, consider the sunlight, shade, and proximity to other landscaping elements. Avoid excessive moisture or areas that get water runoff.

Adding Drainage

If heavy rain is common, dig drainage channels beneath the gravel base layer. This allows water to flow under and away from the bench area.

Utilizing Concrete Adhesive

For added stability, apply concrete adhesive between each layer of cinder blocks rather than relying solely on their weight. This prevents wobbling.

Customizing the Size

Get creative with dimensions! Cut cinder blocks to your exact specifications for a custom bench size. This is great for smaller spaces.

Adding Lighting

To extend enjoyment into the evening, add solar or LED lighting along the edges of the bench or sides of blocks. This creates ambiance and visibility.

Using Different Materials

Swap plywood for materials like concrete, pavers, or pebbles for alternative textures and appearances.

Additional Seating Options

Make your bench multi-functional! Add ottomans, attached side tables, and built-in storage for pillows and blankets.

Modular Design

Use interlocking blocks to create sections that can be rearranged or moved. Great for flexibility!

Adding Greenery

Incorporate integrated planters or raised garden beds to create a living accent. Choose plants well-suited for your climate.

Repurposed Materials

Check construction sites for leftover or used blocks. Repurposing saves money and reduces waste.

Building your own cinder block bench is a rewarding weekend project that creates stylish, contemporary backyard seating. With a bit of planning, simple DIY skills, and creativity, you can construct a customized bench perfect for hosting guests or enjoying alone.

The modular blocks offer versatility, while the wood and cushions provide comfort. Follow the steps for assembling the base, installing wood supports, adding cushions, and applying your unique finishing touches. In no time, you'll have a contemporary, industrial-chic bench that becomes a beloved addition to your outdoor living space for years to come.
