Does My Garden Wall Need a Railing or Balustrade?

When designing or maintaining a garden wall, many people wonder if they should add a railing at the top. The answer depends on several factors, including safety, aesthetics, and the purpose of the wall itself. In this blog, we’ll explore when and why you might need to install a railing.

The NHBC states that Guarding should be provided to ‘structures and retaining land more than 600mm high to which people have access’.  This means that if you have a retaining wall higher than 600mm and there is access to the top, a railing or balustrade should officially be installed.

1. Safety Considerations

One of the primary reasons for adding a railing to your garden wall is safety. If your wall is over a certain height—generally 600mm or more—it poses a risk of falls, especially for children, pets, or visitors. A railing creates a clear barrier, reducing the risk of accidents. This is particularly important if the wall is near a patio, seating area, or pathways.

2. Aesthetic Appeal

A well-chosen railing can enhance the look of your garden wall, adding elegance and style. Railings come in a wide range of designs and materials, from modern, sleek metal to more traditional wooden or wrought iron options. They can complement the overall theme of your garden and add visual interest. If your wall feels too plain or stark, a railing can soften its appearance and make it a more integral part of your garden’s design.

For example, a low retaining wall made from Corten steel could be paired with a matching steel railing, offering a cohesive and polished look while boosting safety.

3. Purpose of the Garden Wall

The need for a railing also depends on the role your wall plays in the garden. If it’s purely decorative and low to the ground, a railing may not be necessary. However, if the wall is retaining soil or creating a levelled terrace, it could have a drop on one side that makes a railing essential.

Walls that border paths, steps, or elevated areas of the garden should also be considered for railings. This not only improves safety but helps define the space, giving clear boundaries in the landscape.

4. Choosing the Right Material

If you decide a railing is necessary, selecting the right material is crucial. For a durable and long-lasting solution, consider materials like steel or stainless steel, which are weather-resistant and low maintenance. Corten steel railings are another popular choice for those looking to achieve a rustic, natural patina over time. For those who prefer a modern look, powder-coated steel railings come in a variety of colours to match your garden’s design.

Ways to avoid installing a railing or balustrade at all:

1. Make the Wall Inaccessible:

If the wall is difficult for kids or pets to access from the top, you will not need a railing.

2. Place obstacles so you can't get too close:

One effective method is to place features at the top of the wall. For example, a series of smaller plant pots or planter troughs can reduce the risk. A wide-flower bed or a grass strip can also be enough to keep people away from the edge.

3. Terrace the garden into a series of smaller steps:

This design strategy not only reduces the risk of a significant fall by breaking up the height into manageable sections but also enhances the visual appeal of your garden. Terracing creates distinct levels that can be used for planting, seating, or decorative features. This adds both functionality and aesthetic value to your outdoor space. By incorporating these steps, you minimize the need for railings while creating a more engaging and visually interesting garden layout.

Conclusion

Whether or not your garden wall needs a railing depends largely on its height, location, and purpose. If children, pets or visitors will be using the area then safety may be a concern, or if the wall is in a high-traffic area, a railing is a smart addition. A well-chosen railing can also enhance the aesthetic of your garden while providing peace of mind.
