The former ASN Co. Building is a highly visible and prominent landmark, especially the towers, from the Harbour and City and forms part of an important historic vista from Circular Quay through to Campbell's Cove and beyond. It can be seen from Port Jackson, from the North Shore, Circular Quay and Harbour Bridge.
When completed the ASN Co. Building was one of the most prominent buildings in Sydney, and remains an extremely prominent landmark. Not only is the building significant as an excellent example of Wardells style, but also the way in which he allowed the site shape to partially dominate the design. Each bay is a different length, stepping down the site. Although there were other buildings of similar style that existed in Sydney, none of them incorporate such picturesque façades with this type of layout nor do they mix office and warehouse design together.
The building is a rare intact example of the late 19th century Anglo-Dutch architectural style.
