The development was part of the industrialist David Davies's scheme for Barry Docks and was intended to regulate the substantial coal exporting trade which had grown to world prominence in the town.
The architect was Arthur E. Bell who was the son of the resident engineer of the Barry Dock and Railway Company.
The building is in Baroque revival style, based on the work of Sir Christopher Wren.
[2] The Dock Offices were badly damaged by fire in 1984 but were later restored by Associated British Ports and now house the part of Vale of Glamorgan Council dealing with building construction and new civil engineering projects.
The statue of David Davies, the man responsible for the building of the docks, stands in front of the offices.
