Koombana Bay

Modus were involved in a developing a prefabricated public toilet building for a high-exposure coastal location in Koombana Bay, WA, for the City of Bunbury. The council was carrying out a landscape redevelopment to reinvigorate the underused Koombana Bay waterfront. As part of this, they needed a durable public toilet facility that would be able to endure the harsh salt corrosion risks that come with any coastal foreshore location. This included chosen materials such as: hot-dip galvanised steel framing, colorbond ultra roofing and aluminium cladding. Manufactured off-site and installed with minimal disruption to the busy public space, the building is engineered for 30+ years of coastal performance. Along with that was the aesthetic integration with the existing and planned infrastructure. The stand out design feature would be the red powder-coated verandah columns.

Koombana Bay sits within Bunbury's multi-stage waterfront transformation, a major state government initiative reshaping the city's coastline. The ablution building was custom designed in-house to match the architectural language of the surrounding precinct. Off-site prefabrication ensured factory-level quality control on every weld, seal and coating, and once the pad had cured, installation was completed in days.

"Working with Modus Australia on the Koombana Bay amenities building was a really positive experience. Their in-house design approach ensured the building integrated seamlessly with the broader foreshore landscape project while being engineered for coastal resilience - critical for this high-exposure location. The off-site manufacturing delivered quality assurance and significantly reduced construction time and disruption in a heavily used public area. The Modus team were collaborative throughout, and we now have a facility that serves our community well and is built to last in demanding coastal conditions."
