…a modular what? Whether you’ve heard the word before or had no idea they even existed until now, the modular wall has been transforming the Australian fencing market for two decades.

But not many people really understand what they are or how they work. Read on to find out everything there is to know about them, and why they are the premium choice in fencing solutions.

So, what exactly is a modular wall?

Essentially, a modular wall (in the outdoor world) is a free-standing wall system comprising different parts, or modules, that slot together to form one solid structure.

In fact, we invented the modular wall in 2002 when our founder, Nick Holden, was advised by the local Council that he wasn’t allowed to build a brick wall in his front yard. Nick has always been a tinkerer and was determined to find a suitable solution.

So, using the power of modular technology, Nick created a product that followed the simple post-and-rail system of a fence but emulated the look of a rendered brick wall. And voila, the world’s very first modular wall was born!

ModularWalls proudly design and manufacture Australia’s original and best modular wall and are trusted by some of Australia’s largest corporate clients, Government departments and thousands of homeowners.

There are endless options to customise your modular wall.

How do modular walls compare to other fence types?

Modular walls bridged the gap between traditional fencing (metal and timber) and brick walls. Before their invention, homeowners could choose between a sturdy brick wall; or a more affordable fence that didn’t offer much in the way of looks or performance.

However, when you throw in modular walls to the mix, you suddenly have access to a premium fencing type for a lesser cost, hassle and installation time of rendered brick.

ModularWalls combines the quick and easy installation of typical fence systems with the aesthetics, strength and durability most commonly found in masonry. 

‘ModularWalls was the only option we came across that provided the look of a rendered wall, was durable, easy to install and economical. They also had so many case studies of people making it look great, so we felt confident in the product,’ shares Gabrielle, a ModularWalls client. Check out her incredible project here

How much do ModularWalls cost?

Compared to other fence types, they’re typically more expensive than metal fencing but in some cases up to half the price of rendered brick.

What are the different modules I can choose from?

As mentioned above, the walls are made of different modules to construct the fence. 

Firstly, the two main modules are posts and panels. By choosing different combinations of these two modules, you can curate the aesthetic and customise your wall or fence. Choices for ModularWalls posts and panels include:


  • SlimWall® uses the slimmest posts for a sleek fence aesthetic, offering both Galvanised Steel or Aluminium options (for coastal or poolside applications)
  • TrendWall® uses a slightly more robust fence aluminium post, allowing you to achieve taller heights and hold thicker panels for additional sturdiness. 
  • VogueWall® offers a masonry-like aesthetic, with posts that mirror a brick pier and offer heights of up to 3m.
  • EstateWall® boasts our grandest posts yet – making it the perfect choice for bold front entrances, statement feature walls and boundary walls.

  • AcoustiMax® panels are our core panel choice for most ModularWalls fence and wall styles, and offers both acoustic and impact-resistant properties.
  • TerraFirm® retaining panels are used for earth retaining capabilities and can be used in a standalone retaining wall or seamlessly integrated into your fencing for a minimalist look. 
Tiling is just one of the many customisation options available with ModularWalls

Secondly, there are also smaller modules you can use to customise your wall further, including:

  • Post tops and wall capping: Flush creates a sleek, modern finish. Alternatively, the External option offers a traditional boxed finish, perfect for more ornate or Hamptons styles.
  • Joining profile: Choose an ‘Expressed Joint’ option to create a distinct design feature from the panel join lines. 
  • Pedestrian gate: Add a matching pedestrian gate for easy access. 
  • Letterbox: Integrate a ModularWalls letterbox for an integrated front wall design.

Are modular walls a popular choice?

Since its inception in 2003, they’ve experienced rapid growth in popularity. In fact, they’re making quite a splash in the design world. ModularWalls has been used by the likes of Three Birds Renovations for their House 10House 11, House 13 and House 14 projects, Shaynna Blaze’s Country Home Rescue and The Designory’s Byron Bay villa, to name a few.

What can you use modular walls for?

Modular walls can be used for a wide variety of applications. These include fencing, boundary walls, acoustic fencing, retaining walls and retaining panels, feature walls, privacy screens, commercial noise barriers and acoustic enclosures. 

Please note that ModularWalls are not designed to be used within the building envelope; they are for outdoor use only.

Who can install a modular wall?

Absolutely anyone! You can choose between DIY Installation or Professional Installation:

DIY Installation

If you are good with DIY projects and have someone to help lift the panels, then you can install a modular wall!

The process is incredibly simple to follow; you just:

  1. Dig the post holes.
  2. Concrete the posts into the ground.
  3. Slide the panels in.
  4. Finish as desired.

In fact, it just takes two people to install, so you can have a new fence in a single weekend (dependent on the length, of course)! If this is of interest, find more detailed info on how to install a DIY modular wall here.
