A Guide to Retaining and Garden Walls: Design, Materials, and Benefits

Retaining and garden walls serve various purposes in a landscape, from addressing slope and erosion issues to providing structural support and aesthetic appeal to outdoor living spaces. Whether you need to control soil erosion on a hillside or want to create a decorative garden bed, retaining and garden walls are versatile and practical hardscape features that can significantly enhance the look and functionality of your outdoor spaces.

These walls, often constructed from materials like concrete, natural stone, or brick, can be customized to best suit your property's landscape design and your desired aesthetic. In addition to addressing soil retention and erosion control, retaining and garden walls can provide valuable landscaping opportunities such as terraced gardens, raised planters, or cozy seating nooks.

In this blog post, we will explore the essential aspects of designing and constructing retaining and garden walls, including the various design considerations, material options, and the benefits of collaborating with an experienced landscape architect. With so many possibilities at your fingertips, planning carefully and making informed decisions that meet your unique needs and preferences is essential.

Understanding the Purpose

Before diving into the design process, it's essential to understand the primary purpose of your retaining or garden wall. Is it to manage a sloped area or to prevent erosion? Or perhaps you're looking to create a decorative element for your landscape, such as a raised planter or a cozy seating area. Identifying the wall's purpose will help guide the design process and ensure that the final product aligns with your specific needs.

Assessing Site Conditions

Before constructing a retaining or garden wall, it's crucial to assess the site conditions, taking into account factors such as soil type, drainage, and the wall's load-bearing capacity. Depending on these factors, it may be necessary to obtain permits or enlist the assistance of an engineer or landscape architect to ensure a structurally sound design.

Determining Wall Height and Length

When planning the height and length of your wall, consider the primary purpose and any local building codes or regulations that may apply. For example, walls above a certain height might require professional engineering or permit approval.

Selecting Materials for Your Retaining and Garden Walls


Concrete provides a durable and cost-effective material option for retaining and garden walls. With its mix-and-pour versatility, concrete can be formed into various shapes and designs, providing you with limitless creative possibilities.

Natural Stone

Natural stone is an attractive and timeless material choice for retaining and garden walls, offering a unique blend of durability and elegance. Popular natural stone options include limestone, granite, slate, and river rock, each with its distinctive appearance and textures.


A popular choice for its classic look and reliability, brick is a versatile and visually appealing material for retaining and garden walls. Available in various colors and patterns, brick walls can be designed to coordinate with existing architectural elements.

Manufactured Block

Pre-cast blocks made from cellular concrete or other composite materials offer a lightweight alternative to traditional concrete or stone materials. These blocks are designed for easy installation and come in various shapes, colors, and textures to create the desired aesthetic.

Incorporating Additional Elements for Added Functionality and Beauty

Adding Steps and Seating

Incorporating steps or seating options into the design of your retaining or garden wall serves to improve overall functionality and offer additional engagement with your landscape. Consider built-in seating for a cozy fire pit area or steps leading through your terraced garden.

Integrating Planters and Greenery

Enhance the visual appeal of your wall by incorporating planters or landscaped greenery. Consider cascading plants or climbing vines to create the illusion of a natural, living wall that softens the hardscape structure.
