Cowbridge Halls to Hertford United Reform Church

Cowbridge Halls to Hertford United Reform Church is a church hall and former caretaker's house built between 1891 and 1892, designed by architect James Farley. The building features knapped flint with grey brick and sandstone dressings, yellow stock brick on the sides, and a Welsh slated roof that is gabled towards the street, with hipped ends on the sides and triangular gabled ventilators positioned high up. It is designed in a free late 13th century Gothic revival style to complement the Congregational Church (now United Reform Church) located to the east.

The exterior has a two-storey front, although the interior is single storey. The ground floor includes a central doorway framed by twin brick pointed arches, with an outer stone dripmould and twin leaf battened doors. Stone kneelers support a stone fanlight featuring heavy plate tracery with three cusped trefoiled circular openings. There are single lancet windows on either side, made of stone with cusped trefoil heads beneath pointed arched stone dripmoulds, linked by a band to the dripmould over the central door. Above this stone band is a large central window with twin paired stone lancets, cusped trefoil heads, and a large circular opening at the center with an inner recessed quatrefoil. The flint infilling is located below the outer stone dripmould and brick double header pointed arches. The building has a moulded band and a brick gable parapet, which has been simplified in reconstruction from the original brick dentil courses, along with stone kneelers and stone coping. Octagonal turrets made of flint with brick dressings are located at the corners, although the former pinnacles are now missing.

To the left and right of the center, there are single storey sections with coupled stone lancets featuring chamfered trefoil heads, a flint panel above, and a brick header pointed inner arch beneath the outer stone dripmould. The eaves of the Welsh slated roof have brick dentil and splay courses. The side elevation consists of two bays of flint, with buttresses made of brick and flint with stone offsets, while the remainder of the flank is constructed from yellow-brown stock bricks, with a two-storey section at the rear for the former caretaker's house.

Inside, the large hall boasts a 5-bay open timber roof supported by braced tie beam trusses and a boarded ceiling.
