This three-storey brick and stone building at the intersection of Osborne Street and River Avenue in Winnipeg was designed by local architect Charles Saunders Bridgman and built by contractor Arthur Chadwick Waller in 1909 for realtor Hartley McKinley Millman. It provided a mixture of retail and office space along with residential apartments.
In its original configuration, the structure was semi-enclosed around an open-air inner courtyard and consisted of two separate blocks: the 12-suite Osborne Apartments / Osborne River Apartments (450 River Avenue) and the 7-suite Osborne River Building (454 River Avenue). The building was briefly known as the Millman Block, although the name was short-lived and discontinued by 1910. A branch of the Canadian Bank of Commerce occupied the corner commercial space from 1910 to 1935.
In the 1970s, the exterior courtyard was enclosed and became an interior space.
In September 2019, it became a municipally-designed historic building.
