The Laurie Ferguson Water Playground in Merrylands, NSW, transforms Granville Park into a flagship splash-park destination, replacing ageing facilities with two custom prefabricated toilet and change room buildings from Modus. The brief was a familiar but demanding one: deliver amenities tough enough for the relentless daily use of a high-traffic open space, meet the park's water treatment requirements, and do it all without compromising the vibrant design vision of the landscape architect, Context Landscape Architecture.

Context engaged Modus early through a design consultation, and the engineers worked directly alongside their team to translate the architectural vision into council-grade modular buildings that integrate seamlessly with the wider playground. The result is two purpose-built structures. The first is a public toilet building with three cubicles, including a universal access suite with baby change facilities. The second combines standard toilets, two family change rooms and two outdoor beach showers, with an integrated pump and maintenance room and chemical drum storage scoped to service the splash park's water treatment needs.

Durability sits at the core of the design. Vertical powder-coated aluminium fascia planking, aluminium ventilation louvres, hot-dip galvanised structural steel, anti-vandal hardware and external CCTV give the buildings the resilience and security a busy public space demands. Just as importantly, the finish was chosen to knit the amenities into the broader landscape plan. Rather than defaulting to a plain, off-the-shelf look, the buildings were finished in Colorbond Dover White with Dulux Sunshine Gloss yellow accents across doors, perforated privacy screens and bench seating, deliberately picking up the playground's bright, playful palette and tying in with the surrounding infrastructure, from the shelters and drink fountains to the play equipment and site furniture. The buildings read as a considered part of the destination rather than a separate service block dropped in beside it.

Prefabrication kept the site works simple. Head contractor CA-I took delivery of the completed modules and finished the installation with minimal disruption on site.

For landscape architects and councils planning their own high-use public spaces, the Laurie Ferguson project shows what early collaboration and modular construction can deliver: durability, design integrity and a build that sits comfortably within the wider vision.
