Designing a Stunning Two Tiered Retaining Wall
A two tiered retaining wall is a visually striking landscape feature that can add depth and interest to any outdoor space. By using two levels of masonry or stone, you can create a dramatic effect that separates different areas of the yard or creates a beautiful focal point. In this article, we'll explore the benefits and design considerations of two tiered retaining walls, as well as provide tips on how to build one.
Benefits of a Two Tiered Retaining Wall
Two tiered retaining walls offer several advantages over single-level walls:
- Increased visual interest: The second level of the wall creates a more dynamic and visually appealing design.
- Separation of spaces: The two levels can be used to separate different areas of the yard, such as a patio from a garden.
- Amplified dramatic effect: The stepped design creates a sense of depth and drama, making the wall a focal point in the yard.
Design Considerations
When designing a two tiered retaining wall, there are several factors to consider:
- Grade and drainage: Ensure that the wall is built to handle the grade and drainage of the yard, and that water doesn't accumulate behind the wall.
- Materials: Choose materials that are durable and suitable for outdoor use, such as natural stone or concrete blocks.
- Stability: Ensure that the wall is stable and secure, with a strong foundation and adequate drainage.
- Height and level: Determine the ideal height and level of the wall based on the yard's grade and desired design.
Building a Two Tiered Retaining Wall
Building a two tiered retaining wall requires careful planning and execution. Here are the general steps involved:
Step 1: Prepare the Site
Determine the location of the wall and mark out the area where it will be built. Clear the site of any debris and vegetation, and check for any underground utilities.
Step 2: Excavate and Level
Dig the trenches for the wall, taking care to level the site accurately. Use a level and a string line to ensure that the wall will be built on a level surface.
Step 3: Build the Base
Build the base of the wall using concrete or a concrete block, making sure it's level and secure. Use a string line to ensure that the base is straight and plumb.
Step 4: Build the Wall
Begin building the wall, using the same materials and techniques as the base. Make sure each course of blocks is level and plumb, and that the wall is stable and secure.
Step 5: Finish and Add Drainage
Finish the wall with a decorative coping or cap, and add drainage to the back of the wall to prevent water accumulation. Use a drainage material such as gravel or a French drain to ensure proper drainage.
Materials and Cost
The materials and cost of a two tiered retaining wall will depend on the design and size of the wall, as well as the materials used. Here are some estimated costs:
| Material | Cost per unit |
|---|---|
| Natural stone | $50-$100 per unit |
| Concrete blocks | $20-$50 per unit |
| Gravel | $10-$20 per ton |
| Drainage material | $20-$50 per unit |
As you can see, the cost of a two tiered retaining wall can vary widely depending on the materials used and the size of the wall. However, with careful planning and execution, a two tiered retaining wall can be a beautiful and functional addition to any outdoor space.

A two tiered retaining wall is a stunning and functional landscape feature that can add depth and interest to any outdoor space. By considering the benefits and design considerations outlined in this article, you can create a beautiful and functional wall that will enhance your yard and add value to your property.
