Pierhead Building, Cardiff

The Pierhead Building stands as one of the city of Cardiff's most familiar landmarks and was built in 1897 as the headquarters for the Bute Dock Company. The clock on the building is unofficially known as the "Baby Big Ben" or the "Big Ben of Wales", and also serves as a Welsh history museum. The Pierhead Building is part of the estate of the National Assembly for Wales, which also includes the Senedd and Ty Hywel. It was a replacement for the headquarters of the Bute Dock Company which burnt down in 1892. Frame's mentor was William Burges, with whom Frame worked on the rebuilding of Cardiff Castle and Castell Coch until Burges's death in 1881.

The Bute Dock Company was renamed the Cardiff Railway Company in 1897. The Pierhead became the administrative office for the Port of Cardiff in 1947. The 1897 clock mechanism, by William Potts & Sons of Leeds, was removed, being replaced with an electronic motor, and sold to an American collector in 1973. It was returned to Cardiff in 2005 and, in 2011, installed as a piece of contemporary art in Cardiff city centre.
