Noise wall design goes above and beyond for Emerald Hills Estate
26 June 2020
ModularWalls prides itself on their unique ability to manufacture custom, modern solutions to age-old challenges. When Macarthur Developments required a highly customised noise wall design for their Emerald Hills Estate, it soon became clear that the specified stone aesthetics were not possible with their current products…so ModularWalls created one.
Macarthur Developments are renowned for their stunning communities across Western Sydney. For their Emerald Hills Estate, they required several kilometres of noise wall to mitigate road noise from Camden Valley Way, a 4-lane arterial road along their frontage.
The noise wall was to be finished in their signature blue colour, which was straightforward enough to include in the wall design. However, council imposed an additional condition that the noise wall must incorporate a sandstone look, to break up the aesthetic and harmonise with the natural sandstone within the wider Emerald Hills Estate design values.
Instead of accepting that this particular aesthetic was not yet an option within their product range, they created one from scratch. ModularWalls developed a sandstone cladding solution to wrap over the face of its VogueWall posts. This cladding was developed and manufactured in-house, serving as testament to their commitment to innovative, custom solutions and the sheer power of manufacturing.
“The ModularWalls team were responsive, they listen, they’re open-minded and they’re also flexible to work to our particular needs. And I guess the evidence of that is in the product; it looks good! And we get positive comments from council, residents and motorists that use the roads, as well.”

There were multiple rounds of assessment, quality testing and refinement, as well as continued consultation with Macarthur Developments to perfect the texture, look and feel of the cladding. Multiple patterns of the silicone moulds were made to prevent any visible repeating of the pattern, with a very precise process to maintain the strength, consistency and organically ‘random’ colour, but within a prescribed spectrum.
Utilising their proprietary AcoustiMax panels, the noise wall comfortably achieved the acoustic attenuation required to mitigate the road noise and protect the serenity of Emerald Hills Estate. Measuring up to 2.1m heights, the final design was truly a work of art, with the full project being deployed over multiple stages of development.
“We’re manufacturers, and we’re inventors, so we use this ability to help our clients; ‘importers’ of products simply can’t do this.”
