Berkhamsted Baptist Church Sunday School Attached to Berkhamsted Baptist Church

Berkhamsted Baptist Church and the attached Sunday School is a Non-Conformist church built in 1864, with minor alterations made in the 20th century. The building is constructed from yellow-grey stock brick with red brick banding, and features ashlar limestone for the spire and dressings. The roof is made of Welsh slate and has coped gables. Designed in the Gothic Revival style, the church has an asymmetrical 'T' plan, with the main entrance facing High Street at the south end.

The church includes a tower with a spire at the south-west corner. The lower part of the tower and the base of the broach spire are made of brick, while the narrow octagonal spire is made of ashlar and has a steeply-pointed lucame on each facet. The south gable features a triple pointed arched entry, above which is a 5-light window with Flamboyant tracery. There is an apsidal porch at the south-east corner with an east-facing doorway.

Inside, the church has a broad nave with side aisles beneath a continuous roof offshuts. The nave is adorned with 2-light pointed-arched windows and multifoiled windows within arched surrounds, all set within panels marked by raised vertical and horizontal bands. The Sunday School forms the head of the 'T' shape, featuring a squat tower at the north-west corner topped with a step pyramidal roof. The wide gables have triple lancet windows on the upper floors and a lower floor at the west end.

The interior is fully galleried, with side galleries supported by 2-stage columns that extend above the panelled gallery fronts to support an upper arcade. This arcade features arch-braced tie beams, longitudinal arcade braces, and aisle beams with struts. The principal trusses carry arch-braced collars. The church contains contemporary furnishings and fittings, including gallery seating and an organ set within an arched recess at the north end. This building is a well-composed and little altered example of mid-19th century Non-Conformist architecture in the Gothic Revival style, prominently located on the street and reflecting the expansion of Berkhamsted's principal street in the 1860s.
