How to Build a Cinder Block Retaining Wall

Curb Appeal Makeover: A Budget-Friendly Retaining Wall Transformation

When Christy sent us photos of her curb appeal makeover, we were excited to share the results. Below is her note about the project and how she and Erik turned an unattractive retaining wall into a handsome, functional feature — all on a very small budget.

First, love the bathroom stripes! I was planning to stripe my laundry nook and seeing that inspired me even more. But I’m writing to share our new and improved retaining wall in the front yard. When Erik and I moved into our townhouse, the property line on the unattached side was marked by a truly awful retaining wall. It was raw cinder block, two rows too short and just plain ugly. Our builder said he would finish it with stucco to match the foundation, but as the builder moved on from our development, those finishing touches never happened. We eventually realized we had to finish it ourselves.

Our plan was straightforward:

  • Add more rows of concrete block to raise the wall to the correct height.
  • Apply mortar to secure the new blocks and create a solid surface.
  • Paint the exterior to improve the look and protect the blocks.
  • Build a decorative planter box to sit on top of the wall and add greenery.
  • Keep the entire project affordable.

We just finished the work a few days ago and we couldn’t be happier with the result. Here’s a brief cost breakdown:

Concrete blocks: free (we found them), mortar mix: $5, paint: $15 (Walmart), wood for the planter box: $30, potting mix: $16, five begonias: $25. GRAND TOTAL: $91!

The transformation is a great example of how smart planning and a bit of elbow grease can dramatically improve curb appeal without spending a lot of money. Rather than seeing the wall as a problem, Christy and Erik treated it as an opportunity to add character and function to the yard. Raising the height corrected the scale of the retaining wall, painting unified the look with the house, and the planter box introduced color and softness through plants.

Here’s why their approach works so well:

  • Structural fix first: Adding the extra rows of block solved the underlying issue of an undersized wall, improving safety and the overall silhouette.
  • Cosmetic improvement: Painting the cinder blocks gives a cohesive, finished appearance and protects the masonry from weathering.
  • Functional decorating: The planter box hides the exposed top of the wall and brings life to the space with seasonal plantings.
  • Cost-conscious choices: Reusing found materials, shopping bargain paint, and selecting a few well-placed plants kept the project under $100.

The end result reads like a deliberate design decision rather than a patch job. Painted masonry feels intentional and polished, while the wooden planter softens the hard edge of the wall. Grouping several bedding plants—like begonias in this case—adds immediate color and will continue to enhance the curb appeal as they grow.

Projects like this are great reminders that you don’t need a large budget to make meaningful improvements to your home’s exterior. A simple plan: solve structural problems, choose one or two cosmetic updates, and add plantings for instant charm, can deliver a high-impact result.

Thanks to Christy and Erik for sharing the before-and-after photos and the clear breakdown of how they accomplished this update affordably. It’s an inspiring example for anyone looking to improve their curb appeal without a major investment.
