Auckland’s hilly landscape offers stunning views, but it can also bring challenges for homeowners. Uneven sections of land often require retaining walls to create usable space and prevent erosion. Building a retaining wall in Auckland involves not just aesthetics, but also legal considerations and structural integrity. This blog will guide you through everything you need to know about building a retaining wall in the City of Sails, including legalities, and why partnering with a reputable Auckland builder might be your best bet for a successful and safe project.

The Legal Landscape: Building Consents and Exemptions

Understanding Auckland’s building consent requirements is crucial. The good news is that not all retaining walls require a building consent. The Building Act 2004 offers exemptions for specific situations.

Exempt Retaining Walls:

• Height: The wall retains no more than 1.5 meters of ground.
• Load: The wall doesn’t support any additional load like driveways, car parks, or buildings.
• Drainage: The wall incorporates proper drainage to prevent water build-up and potential structural issues.

When a Building Consent is Necessary

If your retaining wall doesn’t meet the exemption criteria, you’ll need to apply for a building consent from Auckland Council. This applies to walls exceeding 1.5 meters in height, those supporting additional loads, or situated near waterways. The Auckland council’s online consent tool can help you determine if a consent is required and guide you through the application process.

Beyond Building Consents: Resource Management Act Considerations

While the Building Act deals with structural integrity, the Resource Management Act (RMA) 1991 focuses on environmental impact. Even exempt retaining walls might require Resource Consent if they significantly alter the natural environment. It’s always best to check with Auckland Council to ensure your project complies with both the Building Act and RMA regulations.

Safety First: Building Code Compliance

Building a retaining wall that looks good is only half the battle. Safety is important. Even exempt retaining walls must comply with the Building Code, particularly regarding falls. If there’s a drop of a meter or more from the wall, a safety barrier might be mandatory (refer to Building Code clause F4 – Safety from Falling). Consulting a qualified professional can ensure your wall meets all safety standards.

The Benefits of Partnering with an Auckland Builder like MasterCraft Construction

Building a retaining wall might seem like a straightforward task, but it can be deceptively complex. Here’s why partnering with a reputable us can make all the difference:

A qualified builder will possess the necessary engineering knowledge to design and build a wall that can withstand the elements and support the intended load.
• Experience with Materials and Techniques: The type of material used for your retaining wall depends on various factors like height, load, and aesthetics. An Auckland builder will have experience working with different materials (timber, concrete blocks, etc.) and advise you on the best option for your specific needs. They’ll also be familiar with the latest construction techniques for optimal results.
• Safety Focus: Safety should never be compromised. A professional builder prioritises workplace safety and ensures your project adheres to all safety regulations outlined in the Building Code.
• Peace of Mind: Building a retaining wall is an investment. An Auckland builder will provide peace of mind knowing your project is in the hands of experienced professionals, minimising the risk of costly mistakes or potential structural failures.
