The building was designed by J. R. C. Bethell, the County Architect for South Glamorgan, and built 1986–87. This was at a time when the surrounding area consisted mainly of post-industrial dereliction. Hence the construction of the new building has been described in Buildings of Wales: Glamorgan as a "remarkable gesture of faith the South Glamorgan County Council". It is seen as representative of a new form of civic building that does not dominate its surroundings by its size, or formal language, to the extent that it could "even a deliberate abregation of the arrogant assertiveness of the late C19, expressed across the water". County Hall was officially opened by the Right HonourableLord Callaghan of Cardiff KG, in October 1988. The building is generally three storeys in height, but rises to four and five storeys in places. The distinctive shallow pitch roofs are of black slate. In plan the building is formed around a central courtyard.
Recent developments
On 1 April 1996, under the Local Government Act 1994, South Glamorgan County Council was broken up and Cardiff Council became the local authority in the area and took over County Hall. In September 2007, former Council chief executiveByron Davies unveiled plans aimed at massive efficiency improvements and bringing in additional funding, which could include selling County Hall, the Cardiff Heliport and up to 40% of Cardiff Bus. In 2013 the sale and demolition of County Hall was again raised, as part of Cardiff Council's plans to reduce their property commitments. It was suggested an indoor arena and convention centre could be built on the site.
