Construction of the structure, which was undertaken by Laing Group to a design by the Lanarkshire County Architect, David Gordon Bannerman, in the International (Modernist) style, started in 1959;[5][6][7] completed in 1964 with a ceremonial opening by the Queen Mother,[8] the complex features a 17-storey 200 feet (61 m) office block, a separate debating chamber in a rotunda and an external plaza with fountains. Category A listed,[9] the modernist design was influenced by the United Nations building in New York City.[10][11] Glass curtain walls cover the north and south facades, with the narrow east and west sides being blank white walls.[10][12]
Occupying a prominent position where the A72 and A724 roads meet within the Hamilton West district north of the town's historic centre, its upper floors offer views over the M74 motorway, much of Lanarkshire and parts of Greater Glasgow, and in turn it is the area's tallest building (slightly higher than the numerous residential tower blocks in nearby Motherwell, although some of those have more floors)[13] and one of its most recognisable features.[11] Immediately to the east is the neo-classical Hamilton Sheriff Court building, also Category A listed.[14]
