We recently completed a corten steel cladding project in Geelong, designing and fabricating a custom enclosure to conceal a septic tank system.

Why Corten Steel Cladding Was the Right Choice

Corten steel cladding is increasingly used in architectural projects for its durability and distinctive appearance.

Unlike standard steel, corten is designed to develop a natural weathered finish. Over time, it forms a stable, protective layer. This eliminates the need for painting or ongoing maintenance.

This makes it ideal for rural environments and exposed areas where long-term performance matters.

The evolving patina also allows the structure to blend naturally into the landscape. This works particularly well in coastal and regional settings around Geelong, the Bellarine Peninsula and the Surf Coast.


Where This Fits Within Architectural Cladding

While this corten steel cladding project was designed as a septic enclosure, the same materials and fabrication methods are used in architectural wall cladding, feature façades and outdoor structures.

Corten steel cladding is regularly specified for residential and rural projects where durability, low maintenance and a strong visual finish are required.


Fabrication Completed In-House

We fabricated all panels for this project in our Lara workshop.

Having full control over fabrication allows us to:

  • Manufacture panels to exact dimensions
  • Maintain consistency across all components
  • Reduce delays often associated with external suppliers
  • Deliver a cleaner, more accurate finished result

We designed each section to suit the layout of the septic system while ensuring access and functionality were maintained.


Installation & Site Outcome

Once we installed it, the enclosure transformed the area completely.

What would typically be an exposed and purely functional part of the property is now a clean, structured feature. It complements the surrounding environment and improves the overall look of the space.

As the corten continues to weather, the appearance will evolve further — deepening in tone and adding character over time. Refer to the gallery below to see how the panels looked not long after installation.


A Practical Solution That Adds Value

This project is a good example of how practical requirements on a property don’t have to compromise the overall look.

With the right material and fabrication approach, even service areas like septic systems can be integrated into the broader design of a home or rural property.
