Pontypridd Register Office was built in 1913 in a style similar to Henry Hare's Municipal Buildings of 1904. There is a two-storey nine-bay main wing in a free Baroque style, of coursed rock-faced stone, rusticated pilasters and freestone dressings. The slate roof is behind a plain parapet and is hipped at both ends, but the middle five bays have a heightened ridge with end stacks and central cupola with pilasters and pyramidal cap. The windows have been replaced in their original openings, which are under lintels in the upper storey and mainly segmental-headed with keystones in the lower storey. The central bay has a segmental-headed doorway with keyed head, and replaced doors and overlight. To the rear are three-storey wings with a lower two-storey link, housing the stair, in the centre, with rendered walls, freestone and white-brick dressings, replaced windows, and hipped roofs with brick stacks.
