Cardiff Road Congregational Chapel was built in 1899-1901 in the Vernacular style. It has since been renovated into a children's nursery. The exterior of the building is rendered and painted, topped by a mansard roof of Welsh slate, with terracotta crested ridge tiles. The chapel was entered via porches with hipped roofs at either end of the long wall, in which double doors are topped by paned windows. Between the porches are six paned windows and a further two doors which were added at the time of renovation.
The interior of the former chapel has been completely replaced.
