10 Murray Street

10 Murray Street was the address of the former State Offices building in Hobart, Australia, and the name by which the building was frequently known. It was a brutalist office building located behind Parliament House and close to Salamanca Place. The building was fully occupied by the Tasmanian Government, and was linked to Parliament House via a skyway. 10 Murray Street was demolished in 2018 as part of the Parliament Square redevelopment.

Construction of the State Offices building commenced in July 1966 and was completed in 1969. The design was prepared by architect Dirk Bolt, who had been in partnership with David Hartley Wilson in Hobart since 1958. Later that year Bolt left Tasmania to establish a practice in Canberra, and Wilson, responding to instructions from the then Director of Public Works, modified the design and took the project through to completion, with the building ultimately rising twelve storeys above ground level. The completed building provided additional government office accommodation intended to relieve overcrowding within Parliament House and other nearby State offices. The building had three ground floor levels, including a reception level raised on broad steps above Murray Street, ten floors of offices, and a penthouse level containing the plant room and a caretaker's office. It was constructed in reinforced concrete with an externally expressed structural frame, partly to avoid the expense of imported steel, and its windows were recessed to prevent a glass curtain wall effect. During construction, the former Hydro-Electric Department headquarters to the north (known as Building 4 in the Parliament Square complex) was temporarily supported on steel needling while its original footings were removed and replaced beneath a new sub‑basement at a deeper level. Following completion of 10 Murray Street in 1969, the Public Works Department and the Taxation Department relocated there from the 1937–39 State Government Offices (Building 5). In 1971 major renovations were carried out to Building 5 to prepare it for the needs of the Department of Health, and in 1973 a substantial overhaul of Building 4 was commissioned prior to the State’s Social
