The Ottomin House – A Heritage Landmark
The Ottomin Group is headquartered in Ottomin House on Dalgety Road, Millers Point—one of Sydney’s earliest areas of European settlement and a historic hub for maritime activity.
Ottomin House comprises two heritage-listed terrace houses of State significance. Built in 1847 and 1848 in the Victorian Georgian style, these four-storey terraces were originally known as the Victoria Terraces in honour of the newly crowned Queen Victoria. They are rare surviving examples of Sydney’s early housing stock and among the few remnants of the first phase of residential development in Millers Point.
Constructed from dressed ashlar sandstone blocks—believed to have been quarried on-site—the terraces share a carriageway that once led to stables and coach houses, now demolished. Evidence of convict labour remains visible through the distinctive markers etched into the sandstone blocks.
Over the decades, the terraces have undergone multiple phases of occupation: from private ownership to compulsory government acquisition following the bubonic plague outbreak in the early 1900s, and later as public housing until 2016. When the opportunity arose to restore these dilapidated properties in 2016, the Ottomin Group—long-time resident of The Rocks precinct and passionate advocate for early colonial architecture—embraced the opportunity to contribute to the preservation of these 170-year-old landmarks.
Today, Ottomin House stands proudly within the Millers Point Conservation Area. This historic enclave remains a living example of 19th-century urban adaptation, offering a rare glimpse into Sydney’s colonial lifestyle and urban fabric. For the Ottomin Group, it is not just a place of business—it is a commitment to heritage, and a bridge between past and present.
