Creating Multi-Level Yards With Retaining Walls

Sloped or uneven properties present unique challenges for homeowners, but they also offer exciting opportunities. With the right design and construction, you can turn an awkward incline into a stunning, functional multi-level landscape. One of the most effective ways to achieve this is by building retaining walls.

At Square Leaf Landscaping & Design, we specialize in designing and constructing retaining walls that not only serve a structural purpose but also elevate the beauty and usability of your outdoor space. In this post, we’ll explain how retaining walls can help you create a multi-level yard and why it’s a smart investment for homeowners in Hamilton and surrounding areas.

What are multi-level yards?

A multi-level yard is a landscape design approach that transforms sloped or uneven terrain into a series of tiered, level spaces. These levels—or terraces—are typically separated and supported by retaining walls, which hold back the soil and allow for safe, usable flat ground at each elevation.

Instead of fighting the slope or leaving large portions of your property unused, multi-level yard design works with the natural grade to create visually dynamic and highly functional outdoor environments.

Each level can be customized for a specific use:

• • An upper terrace might feature a paver patio with a built-in seating wall for entertaining.
  • A middle level could include raised garden beds, ornamental shrubs, or even a water feature.
  • A lower level may be designed as a play area, open lawn, or private retreat.

By breaking up your yard into distinct sections, you gain the ability to organize your outdoor space based on how you actually use it—whether that’s hosting gatherings, relaxing in the shade, gardening, or simply enjoying the view.

Perfect for challenging lots

Multi-level yards are especially ideal for homes built on hillsides or uneven ground—common in neighborhoods like Ancaster, Dundas, and Waterdown. In these areas, it can be difficult to use the full yard without professional grading and support.

Rather than attempting to flatten the entire space, our team at Square Leaf Landscaping & Design uses retaining walls to create safe, stable platforms that:

• • Prevent erosion and water runoff issues
  • Make mowing and yard maintenance easier
  • Improve sightlines and property aesthetics
  • Increase usable square footage for outdoor living

This design approach not only improves function—it often becomes one of the most striking and memorable features of the landscape.

The benefits of using retaining walls for multi-level yards

Retaining walls do much more than hold back soil. When thoughtfully designed and professionally installed, they become an essential tool for transforming sloped or uneven properties into highly functional and visually striking outdoor spaces.

Here are the top benefits of using retaining walls to create multi-level yards:

1. Create structure and maximize usable space

Retaining walls allow you to carve out level surfaces on sloped terrain, giving you more space to work with and improving the overall layout of your yard.

With retaining walls, you can:

• • • Add level areas for patios, lawns, or garden beds
    • Separate your yard into distinct “zones” for entertaining, relaxing, or playing
    • Create platforms for outdoor kitchens, firepits, or lounge areas
    • Make better use of steep or awkwardly graded lots

This added structure helps you get the most out of your backyard—especially on properties with limited flat space.

2. Improve drainage and prevent erosion

In areas with elevation changes, rainwater runoff can cause major issues. Retaining walls help manage water and protect your landscape from erosion and pooling.

Properly installed retaining walls can:

• • • Stabilize sloped soil and reduce washouts during storms
    • Redirect surface water away from your home and hardscape features
    • Integrate built-in drainage systems behind the walls
    • Protect your foundation and preserve your landscaping investments

If you’re in a location like Dundas, Waterdown, or Grimsby, where drainage is often a concern, this benefit alone can make retaining walls well worth the investment.

3. Boost curb appeal and property value

Retaining walls aren’t just practical—they’re also a powerful visual element that can enhance the appearance and value of your home.

They help improve your landscape by:

• • • Adding depth and visual interest through terraced design
    • Providing clean lines and architectural structure
    • Creating contrast and definition with other landscape features
    • Offering a high-end, finished look when built with stone or decorative block

This improved appearance often translates to increased property value, especially when the yard is designed with intentional flow and usability.

4. Unlock new design and planting possibilities

One of the most exciting parts of building a multi-level yard is the creative freedom it allows. Each tier becomes a blank canvas for landscaping and outdoor design.

Retaining walls enable creative features like:

• • • Raised garden beds or planting tiers for flowers, herbs, or shrubs
    • Decorative rock gardens, water features, or boulder accents
    • Low-voltage lighting built into wall faces or steps
    • Contrasting textures with natural stone, mulch, and ornamental grasses

Whether your style leans traditional, natural, or modern, retaining walls offer unmatched flexibility to bring your outdoor vision to life.

What to consider before starting your project

Building a multi-level yard with retaining walls isn’t a simple weekend DIY—it requires careful planning, precise execution, and knowledge of structural engineering. A well-built retaining wall system must do more than look good; it must hold back tons of pressure, manage water, and withstand years of seasonal changes.

Before beginning your project, here are a few important factors to consider:

Site grading and design layout

Every property is different, and retaining wall construction starts with understanding the landscape you're working with.

Key elements we evaluate include:

• • Slope and grade of the land – Determines how much excavation is needed and how many tiers can be safely added
  • Soil type and stability – Clay, sand, and loam soils all behave differently under pressure and water exposure
  • Water flow and drainage patterns – Critical for preventing water build-up behind the wall or runoff toward your foundation

At Square Leaf Landscaping, we prepare detailed grading and drainage plans that ensure long-term performance. This not only protects your investment—it also enhances the safety, function, and beauty of your entire yard.

Choosing the right retaining wall materials

The material you choose will affect the look, durability, and cost of your retaining wall. We help clients select options that fit both their vision and their property’s needs.

Common material options include:

• • Concrete blocks – Affordable, durable, and available in a range of shapes and colours
  • Natural stone – Offers a timeless, organic appearance perfect for garden walls or rustic landscapes
  • Boulders – Great for creating naturalized, large-scale terraces with impact
  • Armour stone – A popular choice across Hamilton and Ancaster for its bold, clean lines and structural strength

We’ll guide you through the pros and cons of each material, taking into account aesthetics, longevity, and how the material integrates with other features like paver patios, walkways, or fencing.

Understanding local building codes and permit requirements

Depending on the height and design of your retaining walls, you may need municipal approval before construction begins.

In most local jurisdictions, such as:

• • Hamilton
  • Burlington
  • Oakville
  • Stoney Creek
  • Ancaster

…walls over a certain height—typically 3 to 4 feet—may require:

• • Structural engineering plans
  • Permits from the city or region
  • Property line setback approvals
  • Utility locates to avoid disrupting buried lines or services

At Square Leaf Landscaping, we manage the permitting and inspection process on your behalf. We work with local officials to ensure that all construction meets code, follows best practices, and is completed without delays or surprises.

A recent project: From slope to showpiece in Dundas

One of our clients in Dundas had a backyard with a steep drop that made much of the yard unusable. We designed a two-tiered landscape using stone retaining walls, allowing them to enjoy a level patio for entertaining on the upper tier and a lawn and garden space below.

The results not only gave them more usable space but completely transformed the look of the property. It’s now one of their favorite features of the home—and completely maintenance-friendly.
