Factors to Consider When Planning a Retaining Wall Project for a Sloped Backyard

Here’s one of the most beautiful retaining wall ideas we could find. It’s the ultimate curb appeal wall with lovely, stacked stones, ornamental plants, beautiful flowers, and native shrubs. The only trouble is that it looks nearly impossible to build yourself – unless you’re a master mason! So – we also want to share some more straightforward retaining wall ideas for helping contain erosion and keep your vertical gardens organized. We also have a few tips to help ensure your retaining wall looks and functions at its best.

Building a retaining wall in your sloped backyard may seem daunting. But it is one of those projects that is well worth the effort! With careful planning and preparation, it can be a fun and rewarding project that transforms your outdoor living area.

Not only can a well-designed retaining wall create additional space for outdoor activities, but it can also add a unique visual element to your yard. However, before you start digging and laying bricks, there are a few vital things to consider to ensure the success of your project.

Purpose and Function

The most vital aspect to consider when planning a retaining wall project for a sloped backyard is the purpose and function of the wall. Are you building the wall to create flat areas for gardening or outdoor activities or to prevent soil erosion? Will it need to withstand people’s weight, or is it intended to be a decorative flower border?

Material Selection

Retaining walls can be constructed from various materials, including concrete, natural stone, wood, and brick. Each of these materials has advantages and disadvantages. So choosing options that best suit your needs and budget is vital. At this stage, it pays to weigh up cost vs. lifespan, as the cheapest materials may be more costly to replace in the long run.

Drainage

Proper drainage is essential for any retaining wall project, especially in a sloped backyard where water runoff can be an issue. Consider including drainage pipes and gravel behind the wall to prevent water buildup and potential damage. I’ve seen the problems that a lack of drainage can do with my unwilling eyes when a large terrace wall folded (collapsed) outside our house after heavy rainfall!

Height and Design

The height and design of your retaining wall will depend on the slope of your backyard and your aesthetic preferences. Do you want one large retaining wall to level out the whole area? Or a series of smaller walls to create several terraces? For larger projects, it’s probably wise to consult an experienced contractor or designer to help you determine if any additional structural support is required.

Permits and Regulations

Depending on your location and the size of your retaining wall, you may need to obtain permits and adhere to local building codes and regulations. Research is vital to scout any necessary building permits before beginning your project. If in doubt, check with your local authority first!

(We don’t want them hounding your work after the fact. Or worse yet – in the middle of construction.)

Maintenance

Like any outdoor feature, retaining walls require maintenance to ensure longevity and structural integrity. Be sure to include regular maintenance tasks, such as checking for cracks and repairing any damage, in your ongoing yard care routine.

1. Stone Retaining Wall by Anthony Watson DIY

Building Stone Retaining Wall
We’re starting our list of retaining wall ideas with an excellent choice from Anthony Watson DIY. It’s an ideal retaining wall for elegantly transitioning to a higher ground level. This retaining wall won’t exceed far beyond three feet tall. Since the height isn’t that tall – it makes an ideal DIY project for everyday homesteaders. We’re not saying it’s easy! This retaining wall undeniably requires plenty of elbow grease. But we guarantee a concrete or heavy stone retaining wall like this can last a decade. Or more!

You can’t beat the robust nature of stones regarding the best material for building a retaining wall. This versatile building material blends into the natural landscape. And it will gently become more weathered and beautiful as the years go by. Yes, there will be a lot of heavy work involved. But this landscaping project is well worth the effort.

Brick walls, flat stones, or a natural rock wall have their place. But we also love this retaining wall idea from Adam and Handyman Magazine.

It can also help to reduce water runoff, which is perfect if you want to increase soil moisture for thirsty plants, turfgrass, and flower gardens.

Then check out these raised garden beds by Alberta Urban Garden. We think these could work perfectly in your hilly yard – to replace or work alongside your retaining wall.

6. Retaining Wall Patio Seating Area by Secret Garden of Mine

We found this hidden gem retaining wall idea on the Secret Garden of Mine blog. Instead of building a lofty retaining wall, the idea is to dig a burrowed privacy den for relaxing, unwinding, and chilling. It’s a beautiful contrast to the more prominent retaining walls – and can also house comfy chairs, potted plants, or native shrubs. It’s perfect!

If you’re going through the trouble and effort of leveling out your yard, why not take the opportunity to create space for extra seating too!? The semi-circular sheltered seating area adds a touch of elegance to a grassy sloped yard, and it would make the perfect spot to sit out with friends on an evening around a fire pit.

This simple design would be great for anyone on a tight budget, as long as you’re not afraid of a bit of hard work! If you don’t have any bricks handy, the retaining wall could get made from reclaimed wood instead.

7. Mediterranean Style Terraces For Sloped Backyards by Solé Structural Landscapes

We’ve been researching the niftiest retaining wall ideas – and this unmistakable beauty on the Solé Structural Landscapes website is worth a look.

8. Gabion Rock Retaining Wall by The Mostly Mike sHOW

How I Built My Own Border Wall Cheap
Here’s a unique retaining wall idea for sloped yards. It’s a Gabion rock wall – from The Mostly Mike Show. The tutorial covers all the must-know details, including the history of Gabion walls, cutting the goat panels, installing the Gabion wall baskets, acquiring rock rubble, and more.

If you have a seriously hilly backyard, you will need a heavy-duty solution that is robust enough to hold hundreds of tons of dirt in place. Your foundation is especially vital if you live in an area prone to heavy rainfall or flooding, as saturated soil can soon destroy an inadequate retaining wall structure.

One option is to get a team of structural engineers in, or you could create a wall using gabion baskets. These are large metal baskets filled with rocks, able to withstand the weight of soil even on the steepest of hillside backyards. It’s a labor-intensive but surprisingly cheap way to add structural integrity to your sloped backyard design.

9. Rustic Stone Retaining Wall With Fire Pit

We found another elegant multi-layer retaining rock wall idea using large natural stones and small boulders. We also love the cozy firepit to help finalize the design. It looks like a cozy yard to enjoy roasted garden veggies (or marshmallows). And everyone can relax and let their hair down while safely enclosed behind the privacy wall.

Incorporating a fire pit in a sheltered area next to a concrete block wall is a clever way to stop smoke from blowing everywhere at your next BBQ! I love the built-in stone seating area part of the retaining wall, making it multifunctional rather than just a structural part of the garden.

If you are on a tight budget, secondhand stock tanks are often easy to pick up for very little money!

11. Railway Sleeper Garden Wall Design by Frank Key

Does your backyard have a steep slope worthy of a significant retaining wall? Then consider this heavy-hitting railway sleeper retaining wall by Frank Key. Railroad sleepers are lengthy wooden rails you may recognize from railroad systems. But they’re also a long-lasting way to build retaining walls, raised garden beds, and other outdoor features. Frank Key shows how.

Railway sleepers have long been a common material for building raised vegetable beds, but they are also a popular choice when transforming a sloping backyard. When installed correctly, these wooden beams are strong enough to support a terraced backyard patio area, providing a beautiful natural setting for you and your family to enjoy.

If you can, try and get hold of old oak railroad ties – these have a potential lifespan of 50 years or more! Their long-lasting appeal makes railway sleepers an attractive and durable option when looking for ways to make your sloped backyard usable and family-friendly.

12. Glass Bottle Retaining Wall by Alt. Build Blog

Alt. Build Blog has the most creative retaining wall design. They’re using a bunch of recycled bottles! They don’t only use the glass bottles as a retaining wall. They also use them as a mosaic artwork garden feature. And also a garden bed barrier. We love the idea!

When used as part of a wall construction project, glass bottles are surprisingly robust and can get used when creating complex wall structures that form the centerpiece of your garden design.

13. Earthbag Retaining Walls to Help Protect Vulnerable Trees

Sandbags and earthbags can make excellent retaining walls. And here’s an extreme example. It’s a collection of sandbags trying to save a few coniferous trees from the invading water. We’re unsure if the earthbags will succeed in the long run. However, it can give the trees some added time. (We’ve also seen trees surviving with half their roots nearly submerged in water. But eventually, erosion can pull the entire tree into the river – despite our best efforts.)

Earth and sandbags can work in other applications, too. In recent years natural building materials have become hugely popular, and one of the most versatile options is the earthbag. These are what the name suggests – a bag filled with organic, earthy soil! The joy of this method is that the financial outlay is minimal – all you need to do is buy the bags and fill them with soil excavated from your building site. The resulting wall can get covered with other natural building materials, such as cob or clay. Either can help create a more aesthetically-pleasing finish.

14. Old-Fashioned Rock Boulder Retaining Wall With Colorful Flower Garden

lovely stone wall retaining a beautiful and colorful flower garden
Here’s a classic retaining wall like our ancestors would make using spare stones, rocks, and small boulders. An old-fashioned garden rock wall makes any radiant flowerbed come to life. Like most retaining walls – these require lots of effort, elbow grease, and hard work. That said, an old-fashioned rock wall can last generations.

Don’t be fooled by the simplicity of this project. You would probably need to hire contractors to ensure the construction was built safely for a wall this size. But if you plan on constructing a low-level retaining wall, it should be simple to do yourself using these larger rocks. You’ll need to take your time and work slowly. Otherwise, you risk hurting yourself when lifting, sorting, stacking, and securing these heavy stones! (Don’t go in alone. Ask a contractor. Or, ask friendly homesteading colleagues for help!)

15. Natural Stone and Rock Landscape With Old-School Stone Steps

We’re finishing our list of retaining wall ideas with one of our favorites. It’s another old-fashioned natural stone retaining wall. Nothing ever looks as good as natural rocks and stones. If you’re lucky, you might even have a few lying around your property ready to use. And if you’re unsure how to start, check out this excellent guide teaching how to build a landscape retaining wall from scratch. It’s perfect for managing erosion, hilly yards, or if you want to help manage water runoff.

My final pick of the day made it onto the list because the design is so beautiful! This steep slope has transformed into elegant stone curves with a sweeping concrete staircase running from top to bottom. The staircase has created a series of raised beds with a flourishing garden filled with bright flowers to help attract plenty of pollinators!
