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 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.
