Montague House and Attached Garden Walls

Montague House, located at 31 Broad Street, is a large town house that now serves as a library and adult education centre. It was built in the mid-18th century, refronted and extended in the early 19th century, and underwent further alterations and extensions in the mid-20th century. The building is constructed of brick and features a low pitched slate roof. It has a rectangular central block with projecting flanking wings, a former service wing at the rear on the left, and a 20th-century library extension on the right.

The house stands three storeys tall and includes brick vaulted cellars. The front is symmetrical with three bays, including the projecting wings which each have one bay. A stone string runs at the first-floor cill level, and the wide eaves are supported by pairs of plain brackets. The windows are sash style with glazing bars, and the central door is half-glazed, set in an arched, panelled reveal with a narrow reeded architrave and a circular-patterned fanlight. The ground floor windows of the wings are arched and set within brick recesses.

The symmetrical three-storey side wings are set back and feature parapets with coping, and a deep stone fascia that aligns with the stone string on the main section. The left wing has a blocked window, while the right wing has a six-panel secondary door with a three-pane rectangular fanlight, both topped with crested keystones. Inside, there is an Imperial staircase leading to the first floor, which has stick balusters and wreathed handrails. The building is set well back from the road and retains its original garden walls that belonged to the former 18th-century terraced garden.
