Corunna Road Sewer Vent and Cottage, Heritage sewer vent and cottage in Stanmore, Sydney, Australia.

The site at Corunna Road comprises a tall brick and terracotta vent shaft alongside a Queen Anne revival cottage featuring timber verandah posts and period details. Together they represent a rare example of residential space built directly adjacent to urban sewerage infrastructure.

Built in 1900 by the New South Wales Public Works Department, the vent and cottage are among only two sewer vents in New South Wales with accommodation. The cottage was leased to Water Board employees who maintained the vent. Sydney Water renovated the cottage under its Heritage Assets Project, and sold it at auction in 2017 for $1,405,000, while the vent remains in public ownership.

The structure demonstrates the evolution of public health practices in Australia through its integration of worker accommodation with essential sanitation infrastructure.

The vent shaft stands at the corner of Corunna Road and a rear lane, visible from the street; the cottage itself is privately owned since its 2017 auction, so visitors observe both from the pavement. The shaft is stabilised by newer steel straps, and the inscribed stone panel is exfoliating, so details are best seen up close from below.

The cottage is one of only two sewer vents in New South Wales with attached accommodation, originally leased to Water Board employees who maintained the vent. Sydney Water sold the cottage at auction in 2017 for $1,405,000, while the vent shaft stayed in public ownership.
