The Allan Border Oval Pavilion is a landmark clubhouse in Mosman, which features a monolithic concrete base and a lightweight steel-framed roof. The exposed concrete slab on the first floor required meticulous reinforcement design to prevent cracking. The most notable feature is the seven-metre cantilever canopy roof, supported by a truss-like frame. A significant engineering challenge was anchoring the cantilever to the slanted concrete beam. Partridge addressed this by designing welded steel truss frames to be cast into the concrete, providing both lateral bracing and sufficient hold-down strength. The roof steelwork is expressed at the ceiling level, requiring complex beam connections. Through close collaboration with the architect and steel fabricator, Partridge developed elegant, fully bolted details that minimised on-site damage and promoted sustainability.
